Some bodybuilders add HGH (Human Growth Hormone) or hCG (Human Chorionic Gonadotropin) to their PCT plans. HGH works to protect on-cycle gains and prevent fat deposits after the conclusion of a steroid cycle, but it takes a long time to work and is not useful during PCT unless you used it during your cycle, as well. hCG, on the other hand, is a fast-acting compound that mimics the LH in the body, thereby priming the body to accept the SERM that you will introduce a little later. You truly only need to consider hCG if your anabolic cycle involved a high dose over a long period of time. Otherwise, the SERM should work well enough on its own.
