TweetHCG (Human Chorionic Gonadotropin) : HCG is a replacement for your natural LH (luteinizing hormone). LH is what your body produces to tell your testicles to produce natural testosterone. LH levels drop when using anabolic steroids (HPTA suppression). Using HCG while on cycle prevents testicular shrinkage, speeding post cycle therapy when the time comes. Using Nolva while using HCG helps stop HCG from de-sensitizing your testicles to natural LH.
This is what I was talking about, when I made that post a few weeks ago about using nolva with HCG.. I wish I could find a scientific explanation to it.
Good Find Mick
