Bioidentical Testosterone, Carbon 13 Isotopes, and and Soy

[Guest guest]

This article is abit to take in. However, there are two facts

illustrated by this whole Landis mess and they are mentioned in this

article.

First, no exogenous testosterone is identical to that which is made

by the humand body. Second the majority of pharmacutical testosterone

is derived from soy. This is whether Solvay makes it for androgel or

if your compounding pharmacy makes you a batch of " bioidentical

testosterone " or if a elite anti aging clinic sells you a tube of all

natural " bioidentical testosterone "

Here are a couple excerpts:

By chance, soy plants are the source of MOST pharmaceutical

testosterone. They tend to have slightly less carbon-13 than other

plants that are more abundant in the human diet. Humans make

testosterone from the food they eat, so their testosterone typically

has more carbon-13 than the testosterone that drug companies

synthesize from soy......

.....The test determines whether the testosterone in the athlete's

urine has less carbon-13 than another naturally occurring hormone in

the urine, like cholesterol. The test is considered positive when the

carbon isotope ratio — the amount of carbon-13 compared to carbon-12 —

is three or more units higher in the athlete's testosterone than it

is in the comparison hormone. It is evidence that the testosterone in

the urine was not made by the athlete's body. Landis's difference was

3.99, according to his own doctor.

The current belief is that Landis may have had a massage where the

massuese used androgel as a part of the massage oil/ointment.

The next link contains a quote from Solvay, the makers of Androgel in

which he admits that the testosterone that Solvay uses is NOT

identical.

At the risk of being too redundant, the larger point here is that

most all Testosterone preparations are made from Soy and Yams--

natural ingredients.

The extracts from the soy and the yam have to be synthesised to form

the complete functional testosterone or estrogen molecule, and to

that extent the majority of pharmacutical testosterone starts out the

same. So whether you buy androgel or a " bioidentical testosterone "

cream from a Suzzane Sommers sanctioned provider the main difference

and the difference is the gel or the cream that the bioidentical

testosterone is mixed with.

Education and real science are your best defense against medical

incompetency and marketing hype aimed at your pocket book.
