Bigger Stronger Leaner Competitive Bodybuilding

OK people I just want to say that I was firmly against soy but now I’m not so sure…

Soy Protein Isolate benefits for Bodybuilders
Animal research suggests some great advantages of using soy protein isolate as a bodybuilding supplement. Research has shown that the isoflavone daidzein found in soy-protein isolate might have a gender specific normalizing effect on sex-hormone production. Lab perienced testosterone and growth hormone excretion as well as muscle growth in males, while the female perienced a decrease in these hormones and fat loss.

Daidzein is a key isoflavone found in soy that acts as a potent phyto-estrogen. It is structurally a very weak “pseudo-estrogen” (about 1000 times weaker than the body’s primary estrogen estradiol). This is good news to the bodybuilder because weak estrogens like daidzein will compete with stronger estrogens like estradiol for available receptor sites to “bind” to. By binding to the receptor sites daidzein then “blocks” the stronger estrogens from binding to and activating receptor sites. With the daidzein isolflavone attached, estrogen receptor sites remain inactive. This inactivity further minimizes the negative effects of estrogen in the body. Many researchers believe this effect is the reason soy protein is linked to a reduction in the risk for many forms of breast, endometrial, and prostate cancer. This mechanism works similarly to the prescription drug Nolvadex (tamoxifen citrate)–an anti-estrogen staple in the bodybuilding community.

Research also indicates that the soy-protein isolates may reduce nitrogen loss and keep you in a positive nitrogen balance to better facilitate muscle growth. The human body can only repair and build muscles when it has a positive nitrogen balance.

Of particular interest to the bodybuilder is Soy Isolates high concentration of the amino acids glutamine and arginine. These two aminos are extremely important to a body builder for their ability to release growth hormone, aid in immune system functions, and for their ability to speed muscle cell recovery.

What’s the source?

3

this is an april fool’s joke right?

4

if i can recall correctly- if two agonists are present, will the stronger one not usually bind?

5

The risks that are associated with consuming soy will far outweigh any minute benefits one might receive.

6

The estrogen binding part is interesting but your sources failed to mention the effect on balls.

Please next time leave the link to where you got it from so we can read it all as well :slight_smile:

Menopausal women take soy products to help control hot flashes.These do this by replacing some of the missing estrogen in her body. Powerful stuff!!!

On the other hand …excess estrogen in a male body signals the HPTA axis to shutdown production of testosterone - thus opening
a virtural “Pandora’s Box!”

(Soy-iso’s accomplish this!)

The very people who are now pushing soy are the same ones who, in their infinite
wisdom, put grain at the base of our food pyramid 40 yrs ago! (It’s for agricultural $$$ reasons.)

Will Brink (who seems fairly bright and fairly adept at research) seems to agree that there’s a place for soy in the bodybuilder’s arsenal.

As for me, I’m doing quite well without it, thank you, and will probably continue to avoid it.

I don’t know about anybody else, but I don’t want my T and GH excreted, I want to keep them.

By the way, what does “lab perienced” mean? I think there are some mwords missing there, which might completely change the meaning of the article.

sounds interesting, whats the source and whats the scale of difference - is it great enough to counterbalance the downside?
aaaand how happy dyou feel about it being non-humen experimenterating?

Well than use soy! I’ll stick to GROW!
