HCG, or Human chorionic gonadotropin , which is derived from the urine of pregnant women, is an injectable drug available commercially in the United States as well as many other countries. Pregnyl , made by Organon, and Profasi, made by Serono, are FDA approved for the treatment of undescended testicles in very young boys, hypogonadism (underproduction of testosterone) and as a fertility drug used to aid in inducing ovulation in women. Among athletes, HCG is used to stimulate natural testosterone production during or after a steroid cycle which has caused natural levels to be reduced. Stopping a steroid cycle abruptly, especially when endogenous androgens are absent, can cause a rapid loss in the athlete's newly acquired muscle. When HCG is used to stimulate natural production, a notably pronounced crash may be avoided. HCG is always packaged in 2 different vials,one with a powder and the other with a sterile solvent. These vials need to be mixed before injecting, and refrigerated should any be left for later use.
Package:
1 vial of 500 or 2500 or 5000 IU and 1 vial of water solution
Usage:
Average dose is 1 ampule per week at the end of the cycle.
