LOL.
Let me say right now that any supplement is meant to SUPPLEMENT. That means it helps, it assures health and may result in needing less of a drug. But it is not intended to be a replacement. (Although in some cases it may be all you need).
Yes, POST CYCLE can help with estrogen removal. It's a total PCT for the guy using gear -- liver detox, libido enhancer, estro elliminator.
UNLEASHED increases free testosterone which can be helpful PC but also in between cycles and while "on" to make the most of the extra T.
The other stuff -- primrose oil, pregnonlone etc can be found in any health food store or online supp house.
