Hi. Any of you guys used soy protein supplements, or a mix of soy+whey+milk protein, such as Full Force Mixed Protein Matrix? Good or bad, they're considerably cheaper than whey alone, so I'm thinking of buying one.
A soy isolate is inexpensive, has the highest score on the PCDAAS, is very soluble if instantized, is extremely bland (a good thing), IMPROVES kidney function (unlike any other protein), is anticarcinogenic, is anti-estrogenic, lowers LDL (bad) and raises HDL (good) cholesterol, IMPROVES THYROID FUNCTION, etc, etc--the list goes on and on. But best of all, unlike whey isolate, pure soy isolates exist.
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.
Yeah and who needs erections anyway.
Does soy contain finasteride?Honestly, I just don't think it's worth the risk. A buddy of mine had thinning hair and took finasteride, which definitely worked to grow his hair back. Sex drive disappeared completely after a month or so on it. After he came off, sex drive never returned to normal and eventually the hair that he had grown on the finasteride fell out.
That's what The Industry would love to make you believe, so you buy more expensive whey protein, which is a byproduct of making cheese. It's always hard not to fall into that trap.Don't mess around with your hormones, not worth it.
Also, your imaginary big bad guy 'industry' makes soy protein products as well ...
