I see a ton of different views on this, but still have yet to find a straightforward answer on this. I've done some googles lol and have read that they can be suppressive. It's a shame you can go down to your supplement store and buy them without proper stuff to find once you quite taking them. I've read that it doesn't convert to estrogen so you don't really need a pct/ai but if your testosterone is dropping below normal levels it would be needed? Maybe I'm just uneducated to it or don't know. I feel like there's many levels to this, not a ton of research has been done and if you're uneducated the common thought is "well if they sell it at a supplement store it can't be too bad for me." which is bullshit. Without getting off topic too much my main question is the pct. If they can sell something that is strong enough to make you need a pct, why is it not the same with something for after the fact. I also see members tear into people I'm not asking for nothing so don't assume I am.
