Yep,as Zyg stated,it has been shown to boost endogenous T production by close to a whopping 60%.Very impressive indeed.I run liquidex(which is a thousand times more cost effective for me)in every post cycle recovery period with my clomid,and not only does it boost my endo T levels up,but it keeps that clomid acne completely at bay for me...Absolutely love this shit,haha!
