Mesterolone is one of the strongest binder of SHBG commercially available, in fact, only DHT binds to SHBG more strongly1,2.
As discussed earlier, SHBG plays a very important role in testosterone metabolism. Because mesterolone binds so strongly to SHBG it tends to bump other less strongly bound molecules in the “free” state where they can bind the androgen receptor3. Therefore, some athletes have attempted to use mesterolone for this purpose. They add mesterolone to a cycle if the hopes that more steroid will remain free and active. This would also be true for testosterone and estrogen. Mesterolone would be capable of bumping both of these hormones into circulation as well which may result in androgenic or estrogenic effects.
Dude, no need to be a dick about it. Hey, you don't have to use the supps sold here. I still think adding more protein can do more good than adding higher dosages. Try it. Buy it at GNC or wherever. It won't be as good, but it's your call.
And if you think the board would be better without the supps, well...there'd be no board. The big diff here is that we have stuff that is suited for the enhanced athlete. If you choose to ignore that, fine. Buy being ignorant and dismissive of potential isn't something to boast about.
