I recently started taking this product..... I did it for a mild form of pct after a short pro hormone cycle that was probably toxic as all hell. I feel slightly better when I take this at night.. I'm definitely more aggressive and aggravated when I take it at night but it does seem to help boost my natural test levels back, I think I read that it was a estrogen suicide inhibitor ... Meaning that it binds to the estrogen cell and destroys it before it can cause your estro levels to get out of control... Are their any negative sides to this shit? Let me know fellas-------I just can't believe the shit works ---
