the biggest problem i see in guys trying to come off after many years on is the ridiculously small dosages of hcg they are told to use by absolute fucking idiots on forums. 250-500iu x twice weekly isnt going to do SHIT for most guys.
GV Gill back in 1998 had a case study that demonstrated the power of high dosages of HCG to fix ASIH (anabolic steroid induced hypogonadism, aka what we all have when we come off). He took a young bodybuilding lad who had been through the ringer trying to come off, and some other moron doctor had him on sustanon shots. Gill got him to get off the sustanon and gave him 10k (yes, TEN THOUSAND) ius per week for the first month, 5k/week for the 2nd, 2.5k/week for the 3rd and final month. Within a couple of weeks of starting symptoms were gone, morning and nocturnal erections returned etc etc.
At the 30 month followup, he was completely fine and eugonadal. I reference this study constantly because its one of the only studies with a very long term followup. Most of the shit bbers read about "pct drugs" in literature is short term stuff. Clomid for example, raises testosterone levels .... while you are using it it does nothing to help restore function of any part of the HPTA/HPGA. Same thing with AIs and shit.
