just curious how men who know about soy and estrogens choose to deal with it.
heeeeeeeeeeelllllll no! Save that for soccer moms.
The LORD is my rock, my fortress, and my savior; my God is my rock, in whom I find protection. He is my shield, the power that saves me, and my place of safety.-Psalm 18:2
today at the airport I chose to have an unhealthy egg and cheese sandwich to get some breakfast protein vs having a fruit smoothie with added soy protein. damn them for not having whey to add

Although I don't recall the context of his statements, renown TRT Dr. Shippen comments in his book (The Testosterone Syndrome) that soy can lead to an increase is test under certain conditions.
My lifting partner is vegan and has soy protein. I personally don't like it, I stick with isolates and Golden FinisH complex.

Soy is a complicated topic IMO. Some groups claim the phytoestrogen activity is enough to shut down a male and others claim the SERM-like abilities are actually good for either sex.
I don't really like the taste of it so I have the luxury of waiting for more data. lol
I think I'm moderately allergic to it haha. Good natural defense mechanism for my testosterone levels I suppose. Realistically though, I think soy would only become a problem if you were to supplement with it day after day. But having a soy protein smoothie as a snack at the airport isn't going to affect your serum test levels. It's good for the heart too, but I just wouldn't make it a habit of ingesting soy isolate on a frequent basis if you're a male.
You can also get injection-grade soy-protein isolates.Originally Posted by RenegadeRows;
I don't mega dose soy if I do take it, so I don't think I'll lactate or grow boobs like the guys in the studies. It has never been shown at a significant level to decrease test (or raise estrogen) in moderate amounts. Most studies show a slight increase of test, like Beau mentioned. I don't mind throwing 20g of soy isolate in a shake every now & then. Especially when I get it for free.
yeah, i was lying above, I really just wanted the egg and cheese sandwich. I accept soy in protein bars

there are times where I consume 40-60g of soy protein per day, but it's only when money is tight and I ended up buying the cheaper protein bars that tend to use soy over whey. So, it's never for longer than say, a month.
I avoid it because I don't like the taste and I heard it can turn you into a liberal vegetarian commie who hates the US of A !
hmm, whats the bottom of this? I eat tofu like 5 times a week if not everyday... its a cheap protein meal for me 2.99 for 3 meals w/ 25grams of protein and 14 of healthy fats not to mention the fullness factor.. Is there any link to studies that would be on the topic?
I don't touch it.
i have a study comparing one of the isoflavones (genestein) to raloxofen in its ability to act like a serm....
it has its place, and its place is in PCT
if i am not mistaken there are some soy proteins with the isoflavones filtered out. there are also many conflicting studies on it from reducing to increasing test levels.
if its in a blend whatever i'll drink it, other than that i will not spend money on it...if you're not using whey you're fukin' up!
soy protein consumption can cause breast tissue in men as well as decrease in testosterone, basically gyno believe it or not.
yes and no........
at high doses genistein can act as an anti estrogen,
yes it can decrease testosterone slightly butttt heres a study...

Résumé / Abstract
The phytochemical flavonoid genistein has been shown to act as a potent competitive inhibitor of human adrenocortical 3β-hydroxysteroid dehydrogenase and cytochrome P450 21-hydroxylase activities in vitro [J. Steroid Biochem. Molec. Biol. 2002; 80: 355-363]. In the present study, we evaluated the effects of large amounts of genistein continuously administered to weanling rats, particularly on steroidogenesis at the pubertal stage in vivo. Serum concentrations of free and total genistein were significantly higher in the 40 mg/kg genistein administration group when compared with the control group. In genistein administered rats, adrenal weight was significantly higher. Furthermore, a clear expansion of cells was observed in hematoxylin and eosin stained tissue at the zona fasciculata and zona reticularis of the adrenal cortex. However in the testis, no differences in weights or histologic changes were observed. Serum corticosterone concentration significantly decreased to 50% of control levels by 40 mg/kg genistein administration and testosterone also tended to decrease with this dose of genistein. On the other hand, although serum follicle stimulating hormone was unchanged, adrenocorticotropic hormone and luteinizing hormone levels increased with genistein administration. These results suggest a significant effect of genistein on steroidogenesis in the adrenal gland and testis of rats, and this effect appeared to be more evident on steroid production in adrenals than in testis in vivo.
i dont know how it can do both, but it does....
i have a billion studies,,,, but this is why it should be used with something like 3-OHAT
