Soy Proteins??

  1. Soy Proteins??


    I just bought a jug of mhp Probolic SR, which has alot of soy protein in it. I was wondering how good of a protein powder this is, ive read that soy converts into extra estrogens in the body. Has anyone had experience with soy protein and/or MHP's Probolic SR?


  2. Where on pub med did you read that soy protein converts? I take soy every day look at my pictures and tell me soy makes me have boobs. Endless your reading mags its not true at all.

  3. Soy contains many isoflavones which act like estrogen in the body correct?

    All im really looking for is if this protein i got half off is any good.

  4. This is as far as i know on this topic. They are like estrogens because they bind to estrogen receptors, much like estradiol and estrone do, but they produce a very weak estrogenic effect. So, my theory (no evidence to back this up) is that it works somewhat like Tomaxifen works. It will clog up estrogen receptor sites so that harsher, stronger estrogens like estrone can't attach and produce feminine affects. Technically, total estrogen levels may come up higher on a test, but you will see far less estrogenic side effects. Again, this is what i've come up with. it's my theory from research. I believe probolic is a good protein powder, but i never used it myself. it combines fast and slow acting proteins to give a "time released" affect. Hope that helps bro.

  5. Ive read that its pretty weak also.

  6. One of the best proteins you can get is Hydrolyzed Casein. The di and tri peptides absorb 3x better than free form amino acids or longer chain proteins. I would avoid Soy protein altogether, I have heard of the phyto-estrogens in Soy than inhibit Testosterone Production. Hopefully somebody with more knowledge bout this will chime in.

  7. Ive also read soy can raise estrogen levels. Its garbage both IMO and IME. If youre after slow digesting casein all the way

  8. To the OP, if you want the fastest and fully absorbing protein go with Hydrolyzed Casein

  9. damn, looks like i have to sell this **** to one of my friends, it goes for 69.99 at gnc, but i got it for 17.49 b/c i goes out-of-date in january.....i thought i got a good buy.

    Ergo-log has tons of good info and study references.

  12. Keep this simple, avoid soy like the plague. The list of health problems is growing every year. It contains plant based female hormones called phytoestrogens. There is nothing good that can come from choosing soy over other higher quality proteins.

    Even if you are a vegan then choose pea or rice protein instead and protect your health.

    Nothing good? Is reduction of bad cholesterol and prevention of prostate cancer nothing good? Anyone who uses anabolics should be especially interested in both of those benefits, I would say. If you need more references that soy phytoestrogens don't actually function as estrogens int eh body, consider that gyno isn't rampant in China, and they eat a TON of soy. Here's a couple more references, though, just in case.

    Most of that is going to be genetic. On the other hand, look at the build of Japanese Sumo wrestlers. The Japanese eat the hell out of soy, too. Bottom line, is if soy were to be avoided so as to not be full of gyno symptoms, Asians in general would have a pandemic of gyno. Obviously, this isn't the case.

    I'm not saying it's the ideal protein, but it's also not to be shunned, since it has many health benefits, especially to those who use anabolics. Refer to the earlier post about prostate cancer protection and lowering of bad cholesterol. That ought to be great news to anyone who uses anabolics.

  16. I don't believe all the hype about soy and estrogen but I still go with whey or casein. Thus my experience with soy is limited and I probably wouldn't chose to buy a soy protein in the future. That being said,
    Keep this simple, avoid soy like the plague.
    is a bit over-dramatic IMO.
    Back.... for real this time

  17. Interesting study showing how soy can actually lower estrogen levels.

    Well, I live in Japan and recently a documentary aired on TV, showing how a lot of young men have very low testosterone and way too high estrogen levels. They even showed that a bra for men is sold. What could that be for?
    (Probably due to the fact that the soy industry is one of the country's biggest, bigger than rice,) Their conclusion was it's stress related.

    Just my 2 cents.

  19. I recommend staying away from soy because it is a cheap form of protein. It's funny how
    MHP claims their protein is so great but when you look at their label the first protein
    listed is soy which cost like $4.50 a lb. then it list whey concentrate which is $5.50 a lb.
    and then the last is calcium cassinate which is actually more expensive than the first two
    at $9.50 a lb. all of these are not the best in quality but it makes MHP more profit. If they really wanted to put out a quality protein blend especially at the price they are charging for a container the first protein in their blend should be whey isolate, micellular
    casien, and egg white protein that blend would be worth the money.

  20. i take soy pre workout a whey post casein at bed time works for me. i read soy boost no levels. and lowers estrogen levels.

    The Japanese are very hard chargers and the place is overcrowded. It stands to reason they're probably stressed out. I would say many Americans probably have low test, too.

    In any case, I'd refer to the above study that shows how soy can actually lower estrogen levels. Take your pick...a documentary or a study.

  22. I've seen a few here bashing the positive studies but no one has even put up a reference to support the negativity. Don't just say its a bad study and have absolutely nothing to back it up.

    Since when does price equal effectiveness? The entire Supp industry is over priced IMO.

    Soy has good bio-availability and a balance of all the aminos. If you got it at a killer price then good for you. Use it.

  23. There have been rumours circulating around soy for some time.

    Its not worth the risk IMO.

    Interfering with test production is the main reason cited. How it interplays in the androgens I dunno. A top nutritionist I hired told me never to touch it as a main protein source, but okay in occasional doses. They were hazy on the reasons too.

    Their advise was to use pea protein if you want a veg. source.

    um, wouldnt hydrolyzed WHEY absorb faster than hydrolyzed casein? since whey digests faster than casein...


    also, since casein builds up in the gut..........which is why it absorbs slower...which is why most people take it before bed.......


    in fact, what the heck is the point of hydrolyzed casein? lol. people LIKE the fact that it is slower releasing so why would they make, or you take a faster releasing more expensive form of a slow protein instead of taking a faster releasing and more bio available protein like whey? if in fact you were looking for speed of absorption....

    you just dropped a paradox on me lol.
    For me, the action IS the juice.
