Natural Height Growth Podcast, Episode 9 – Guest Thomas Samaras From Reventropy Associates And Discusses His Research On Human Stature

Logo1In this episode of the Natural Height Growth Podcast we have a very interesting guest Thomas T. Samaras of the research group Reventropy Associates and the website who comes along the podcast to take the opposite side of the arguement and plays devil’s advocate to the basic premise of this website.

Episode #9: Guest Thomas Samaras From Reventropy Associates And Discusses His Research On Human Stature

We go into the subjects of….

  • What his decades of research has shown about how human size and height is correlated with our longevity.
  • How diet seems to be correlated with our longevity.
  • How large bodies are linked to higher instances of cardiovascular based chronic problems.
  • Why it may be better to decrease the amount of food we are consuming
  • The sustainability of our current consumption rates.

I will also link with this podcast the PDF Tyler from would also accidently find and forward to me about the interesting thesis made by Samaras on human stature towards our overall health and the sustainability of the human species on Earth. The title is “Commentary. Human growth, height, size, Reasons to be small” which is also published at  Volume 2, Number 3, March 2011Journal of the World Public Health Nutrition Association, Published monthly at

Product Review On Growth Sinerama WMX from Grow Taller Lab Or

I think it was the now currently dead Zar De La Estatura blog/website which briefly talked about this other Grow Taller product being sold on the internet called Growth-Sinerama WMX. It is sold from a website 

The benefits they claim are…

  • Stimulates natural growth.
  • Increases bone’s strength
  • Increases energy levels and exercise endurance.
  • Increases height – You will grow taller faster.

It is a 100% herbal height increase formula. The formula is sold in pots, and 1 pot costs $170, while 3 pots cost $480 and it seems to come with free carob molasses (what the hell is that?)


I am always curious at how these internet marketers try to justify why their product will work. This is what the seller say…

“Sleep is the major stimulator of growth hormone, the intake of Growth-Sinerama just before sleep promotes sound sleep and thus helps in promotion of Growth hormone during first hour of natural sound sleep.”

“Consuming “Growth-Sinerama” helps body to produce natural amino acids to the maximum and thus indirectly promotes pituitary gland to produce Growth hormones”

When we see what is actually inside the pot being sold, the active ingredients are..

Growth-Sinerama Advanced ingredients: Carob-flour, Wheat flour, Rye flour, Milk powder, Oat flour Cinnamon.

I have never seen any Grow Taller and Height Increase Supplement or pill that shows that it has ordinary household kitchen food compounds listed as advanced ingredients. Wheat flour, rye flour, and oat flour, are all carbohydrate which would do nothing for the human body except give it glucose and convert it into glycogen for a quick energy source. Carob flour I cam not sure what it comes from but it is still a grain which probably ends up as a sugar energy source when broken down to the components. Milk powder and cinnamon would do nothing either.


There is absolutely no way in hell it is going to help even kids who are still grow taller. The fact that a person is supposed to take grains, milk powder, and cinnamon to make them taller has no scientific basis. the only way it could even help a growing child become taller is if the child has no form of nutrition intake and is malnourished and suffering from stunted growth. Other than that, this product called Growth Sinerama WMX is just a pot of flour and a scam.

Product Review On The Grow Taller Satogrowth Formula At

This is from another grow taller formula or supplement which I had found from looking at the tracking statistics of the website and noticed that someone somehow found the website by typing in the term “Satogrowth Formula”. Naturally I got curious to see what other internet marketing scam was selling another bogus grow taller miracle pill.

satogrowth grow taller formulaAnd I was not disappointed with what I found. Sometimes I do wonder just how many of these crazy schemes and herbal formulas are there on the internet space which offer the same result but not one of them can give any type of real results.

So what will this product be offer or say that can be anything different from the dozens of other height increase creams, pills, sprays, or programs out there?

I will put away my bullshit detector for just a few minutes to see there is anything that is valid about the offering.

Analysis & Interpretation:

I am willing to say that the website is at least slightly better designed in terms of being better looking than some other products I have reviewed before. There is at least a picture of someone who looks like a doctor. His name is Dr. Mirkin Alyco. Do I believe that this doctor at least exists? I don’t know and I don’t want to put the effort to spend even one minute to find out whether Dr. Mirkin Alyco really does exist.

What is the product supposed to do?
What Are the Key Benefits of Satogrowth Formula?
. Helps to improve bone strength and regeneration.
. Helps to improve overall posture and self-image.
. Helps to improve your current height and health.
. Helps to prevent bone resorption (bone loss).
. Helps to maintain good health.
. Helps normal development and maintenance of bones.
. Rehabilitation of spinal discs and thickening of cartilages.

. Improves growth in joints, cartilages and discs.

So what are the active ingredients inside?

Satogrowth Advenced ingredients: carob pulveris, gingiberi , turmeric , galanga , ginseng , ginkgo biloba, gelee Regalem , pollen , specialis mixtio de satogrowth

How does one take this compound?

Satogrowth Directions: Mix one teaspoon (approximately 3gr.) satogrowth with a full glass of low-fat milk and take once every two days in the morning on an empty stomach,take it one hour before meal or two hours after food.

It seems that this grow taller product or at least the website has been around since 2006 since it is copyrighted from 2006-2013. The website has only 6 main webpages. the information is lacking.

The thing that would really determine whether this product would ever have a chance of doing what it is claimed of it would be from looking at the active ingredients. The carob pulveris seems to refer to dust made from pounding locusts or insects. The gingiberi is just ginger. The turmeric is a anti-inflammatory anti-bacterial food supplement. The galanga is another type of ginger. the ginseng is a well known herb, ginkgo biloba is supposed to help improve memory. gelee Regalem is a compound which I have never heard before.

Conclusion: Whoever is selling the satogrowth is telling the prospective buyer that the product will make them taller. After reviewing the active ingredients inside, most of which are plants an dherbs used in traditional eastern food and medicine, there is not one compound in the satogrowth product which has any type of osteogenic or chondrogenic potential. If the compound would ever help a person, it might help the still growing child be able to stave off illness and infections, which can lead to slight stunted longitudinal lengthening. If this product is sold to adults or people with bone maturity hoping to grow, it will not work.


Product Review On JMEXY Growing Taller Formula

Someone who managed to find the website the other day was apparently researching another grow taller program or supplement called JMEXY so I decided to do another grow taller product.


jmexy grow taller formulaFrom a look at the design of the website, I sort of realize right away that the compound would never work. The website is only 5 webpages of content. Two of the pages is to 1. order the product and to 2. contact the product’s suppliers. It seems that the contact information is from the city of Santa Cruz or Lima in Peru. In terms of price, a 3months supply would cost the person $150 while a 12 months supply would cost $450.

The formula is supposed to be from western derived special herbs and it is a special formulation.

The other thing is that the product website is supposed to be copyright since 2012 but it feels like the design of the website is from something 10-12 years ago.

I don’t even want to go much further in this review. This thing just doesn’t work, at least for adults with bone maturity. Give up and move on to something else. I hope no one ever will pay $150 for a 3 month supply of whatever is really inside this “special” herbal formulation.

The Concept Of Youngs Modulus, Stress, And Strain Explained For The Application Of Bone Tensile Loading Or Bone Stretching (Important)

I felt that after the last big scientific post “Would A Tibia Subjected To High Intensity Dynamic Mechanical Tensile Loading Fracture Or Elongate Through Stretching First?” I had to write a final, conclusive post on explaining whether the idea of bone stretching is even possible. 

At this point, if one is looking for a yes or no, question, I would lead to the side that says that bone stretching is probably not feasible. This means that all of the previous efforts by other height increase seekers were probably never supposed to work. I wanted to give a personal interpretation on some engineering principles I learned years ago to show why the idea of pulling on the bone most likely will not result in longer bones, just broken bones.

Let’s look at the mechanical engineering or materials science explanation of what is known as the Youngs Modulus concept. In addition, we look at the engineering concepts of stress, strain, plastic deformation, brittleness, stiffness, elasticity, and a whole lot of other Materials Science & Engineering basic concepts.

Note: One of the focuses in my undergraduate degree was in Material Science so I might wish to talk a little more about the engineering aspects and the calculations than the average height increase researcher or height increase seeker might wish for.

Along the way I will be combining all of the terms above to dissect the diagram of the stress – strain curve, the Modulus of Elasticity, tensile strength, as well as the Yield Point aka Yield Strength aka Elastic Limit

First of all, I am proposing that the reason we are even talking about mechanical engineering & material science concepts is that we are hoping to eventually figure out how much of a load (aka force over area) we would have to apply in a tensile way to pull the average adult male human’s femur bone to a point where it will stretch out, where the bone will not just spring back to the original length, and that the bone will not fracture or break in a critical way, hopefully.

From the older posts…

I will be referencing and using as a guide to write up this post.

The scientific studies and articles I will be citing are…

So the million dollar question is, what is the load in units of Newtons/meters^2 or Lbs do we need to really pull the bone apart to a point where we do get plastic bone lengthening which is not just elastic and will snap back to the original length when we decrease the load?

In a very recent post “The Values For The Magnitudes For The Forces And Loads Needed To Increase Epiphyseal Cartilages Thickness And Human Femur Bone Without Fracture (Important) I had using two major assumptions and guesses calculated the value of the needed load to be 20,000-30,000 lbs of force needed to create the needed force over area to pull the adult human femur bone apart, resulting in either fracture or plastic deformation.

For the reader, this would seem extremely high. The fact that most normal average sized 4 door sedans weight around 2500-3500 lbs shows just how large of a weight would be required to stretch out a single adult male human femur bone. It would require around 10 of these cars put together on a scale before the bone is supposed to snap beyond the elastic range.

So what exactly are we talking about when we keep on talking about these terms called stress, strain, loading, forces, tension, tensile strength, etc? Let’s go over some basic engineering principles.

Engineering Principles Of Stress & Strain & the Stress-Strain Curve

The concept of stress has the units of Newtons/meters^2 so it is the same idea as pressure. In the field of engineering mechanics, the concept of stress refers to “…the internal forces that neighboring particles of a continuous material exert on each other” (Wiki)

From the website

“….The stress field is the distribution of internal “tractions” that balance a given set of external tractions and body forces.”

For our application, we are only looking at what happens to an object when being pulled in opposite directions along the axis which can be simplified aka idealized into a long cylinder (I think a human femur sort of look like a cylinder) for easy calculation reasons. So from the Wikipedia article on the different types of stress…

“Stress is defined as the average force per unit area that some particle of a body exerts on an adjacent particle, across an imaginary surface that separates them.

concentric annular cylinderBeing derived from a fundamental physical quantity (force) and a purely geometrical quantity (area), stress is also a fundamental quantity, like velocity, torque or energy, that can be quantified and analyzed without explicit consideration of the nature of the material or of its physical causes.”

The way to view stress is basically a force of a certain magnitude being applied across the area of the bone. We are looking at the pulling effect. We can even use the term “load”, “stress” or even “force” interchangeably since the way we set up the system for engineering analysis is very simple. The bone turns into a annular hollow cylinder which is where a smaller diameter of cylinder made of a softer composition is enclosed in a larger diameter cylinder made of a harder material.

From the diagram on the right, the force/stress/load will be pulling at opposite directions.

tensile forceNote: Technically the terms force and stress are completely different concepts in normal physics and engineering situation but our system analysis is very simple so I will be using the two concepts interchangeably.

So the stress is on the axial axis so we can say that the force is tensile. Refer to the picture to the right.

The concept of Strain is a little more subtle. The units of Strain are dimensionless but a look at how the concept of strain is defined reveals what strain is refering to…

Strain = (L2-L1)/L1 where L1 = length of the object having stress exerted on it originally and L2 is the new length of the object from the application of the stress. Another term that is very similar in concept to strain is deformation (for mechanics) and deformation (for engineering).

From the Wikipedia article on deformation using the field of material sciences and engineering, the definition is….

“…deformation is a change in the shape or size of an object due to an applied force….can be a result of tensile (pulling) forces, compressive (pushing) forces, shear, bending or torsion (twisting).” 

“As deformation occurs, internal inter-molecular forces arise that oppose the applied force. If the applied force is not too large these forces may be sufficient to completely resist the applied force, allowing the object to assume a new equilibrium state and to return to its original state when the load is removed. A larger applied force may lead to a permanent deformation of the object or even to its structural failure.” 

So in a way, the term Deformation and Strain can also be used somewhat inter-changeably in our discussion. Now let’s see what is written up about the term Deformation…

stress strain curveThe thing to note is that there is two difference types of deformation, 1. elastic and 2. plastic.

Elastic Deformation

This type of deformation is reversible. Once the forces are no longer applied, the object returns to its original shape.

Normal metals, ceramics and most crystals show linear elasticity and a smaller elastic range.

Me: When we look at the graph above, the elastic region is the first part where the stress applied is not that high. The graph shows that as the stress applied rises, the strain also rises, but not at the same degree of change. The change is linear, but since the object or material we are looking at is so hard and strong, the strain, which is the change in length from a tensile force, will be very small while the stress will be very high.

The thing to remember about this graph is that it is not showing something that is happening as a process, throughout time, but something that is happening from repeating testing of different loads aka stresses. There seems to be a upper limit to the amount of stress but there is no limit to the strain. This means that the material at some maximum point will break or stretch out.

Looking at the charge again, we see that using elementary Geometry principles that the term Young’s Modulus refers to the slope of the stress-strain curve. The stress is the variable we chart or graph on the vertical axis while the strain is the variable we chart and measure on the horizontal axis. The slope, which is rise/run is the Young’s Modulus. Intuitively when we try to visualize what the Young’s Modulus would mean from a physical representation point of view, we can say that it is the amount of foce we have been putting on the area of the object over the amount of small length changes that the bone actually goes through. So the larger the Young’s Modulus, the less that the material will deform in the direction that we want.

From Wikipedia….

Young’s modulus, also known as the tensile modulus or elastic modulus, is a measure of the stiffness of an elastic material and is a quantity used to characterize materials. It is defined as the ratio of thestress along an axis over the strain along that axis in the range of stress in which Hooke’s law holds. In solid mechanics, the slope of the stress-strain curve at any point is called the tangent modulus. The tangent modulus of the initial, linear portion of a stress-strain curve is called Young’s modulus. It can be experimentally determined from the slope of a stress-strain curve created during tensile tests conducted on a sample of the material.

Update: 5/11/2013: it would seem that I have new information showing just how incredibly high the Young’s Modulus value is in human cortical bone.

Reference: Rho, JY (1993). “Young’s modulus of trabecular and cortical bone material: ultrasonic and microtensile measurements”.Journal of Biomechanics 26 (2): 111–119.

Values: 14 GigaPascals or 2,030,000 psi

Comparison: If we look at this high young’s modulus versus other compounds on the Chart for Young’s Modulus article on Wikipedia, we find other values like for polypropylene, nylon, rubber, tooth enamel, and different types of steel. In comparison, it would seem that the elastic nature of cortical bone may not be as high as previous expected, if it is true that human cortical bone may just be around 7X the resistance against deformation as polypropylene and only around 20% of the strength of human tooth enamel.

There is two main things to note that is important as well. That is that there is a major different between the Yield Strength and the Ultimate Strength. Sometimes the terms Yield Strength and Ultimate Strength is used interchangeably but I wanted to make a point that for our application, we have to differentiate between the two terms.

  • Yield Strength – When the object moves past the range where it would exhibit elastic behavior, where the change in stress levels would correlate in proportion to the effect of changes in the strain.
  • Ultimate Strength – This is the lowest limit of what the stress can be and the resultance changes in deformation (aka distraction or lengthening) will happen to any magnitude without the need to increase the stress. For bones, being rather materials, it would most likely be the point where the bone material starts to fracture. 

On a personal educated guess, I would think that there is never a truly only elastic effect. There will always be fractures in the bones, just that the fractures are small and microscopic so on the macroscopic level of measurement, we don’t notice the fractures.

Linear elastic deformation is governed by Hooke’s law, which states:

\sigma = E \varepsilon

Where \sigma is the applied stress, E is a material constant called Young’s modulus, and ε is the resulting strain. This relationship only applies in the elastic range and indicates that the slope of the stress vs. strain curve can be used to find Young’s modulus. Engineers often use this calculation in tensile tests. The elastic range ends when the material reaches its yield strength. At this point plastic deformation begins.

Plastic deformation

This type of deformation is irreversible. However, an object in the plastic deformation range will first have undergone elastic deformation, which is reversible, so the object will return part way to its original shape.


stress strain curve ductileFrom the same Wikipedia article, we can see another example of the stress-strain curve, but one for a more ductile material.

I would like to note that sometimes the stress-strain curve is drawn differently due to how brittle, elastic, or ductile a material can be.

Brittle materials don’t have a very large range between the Yield Point and the Ultimate Strength point, if any at all. There is no necking or strain hardening.


This post is to do one main thing, which is to resolve the subject of ever trying to “stretch” or “elongate” the bones using 30 lbs weights strapped to the shins, ankles, or or parts of the limbs. In the posts “Increase Height And Grow Taller Using Ankle Weights , Part I” and “The Thigh Bone Routine Of EasyHeight.Com” I referred to the old height increase researcher Sky trying to pull his bones to elongate them. That didn’t work and he tried for over 5-6 years to find something that worked.

In a recent post I had shown that about 30 lbs is what would be needed to distract the femur bone of a young laboratory rabbit with a lot of growth plate cartilage. That resulted in hyperplasia.

The thing I really wanted to emphasize and to close down the possibility of ever trying a stretching motion using a constant or even linearly increasing load like putting ones leg in a corkscrew device to slowly pull at the adult human leg bone without at least first creating a small fracture or distraction to decrease the amount of tensile load needed dramatically.

I thought I could conclude and state a definitive answer of “NO” for the idea fo stretching bones from writing this article but it seems that more research would need to be done to resolve this issue for good.

A Critical Mistake I Believe I Made On On The Feasibility Of Increasing Periosteum Thickness For Height Increase

Something that I became only very recently aware of about the anatomy of long bones might jeopardize a lot of the research and proposed ideas on how to increase height has come about.

periosteum and articular cartilageIt seems that for long bones, underneath the articular cartilage at the ends on the epiphysis, there DOES NOT seem to be a layer of periosteum!

All that you need to do is look at the diagram/picture to the right which I found from another website to see that the periosteum does not go under the articular cartilage, but moves around the cartilage once it reaches the synovial joints.

Something that I have been claiming for at least a few posts was the idea of stimulating the periosteum which I believed before was under the articular cartilage at the end of the long bones. New pictures and diagrams seem to show that it is not true.

Due to how the process of appositional growth seems to function (at least at my level of understanding months ago), where the thickness of the cortical bone layer of the long bones seems to stay constant, even though the periosteum is supposed to be constantly making new layers on the outside, I had assumed that for the long bones to stay with the same length over time there would be needed a periosteum layer on the ends of long bones as well. The rate of osteoblasts and the rate of osteoclasts are supposed to be equal where the amount of bone matrix removed is about the same as the amount of bone matrix stimulated.

I imagined that the long bones were like long, thing cyclindrical rods and the two flat ends, like the long outer surface, was being regenerated constantly. It seems that this is not the case. The articular cartilage seems to be the tissue that keeps the bone tissue underneath it from being rubbed away due to friction.

I didn’t realize that in the anatomy pictures and diagrams in long bones, the periosteum doesn’t surround the long bones completely. It seems that they don’t cover the ends but that articular cartilage does that. There is no periosteum underneath the articular cartilage of the long bones.

If this is the case, I suspect that I have been wrong in many of my old posts, and for us to succeed in our endeavor, it would be much harder.
