The main reason why Post CT was developed is to be as a replacement for human chorionic gonadotropin (HCG) on cycle and in post-cycle therapy (PCT).The advantage to using Post CT on cycle is that it reduces Hypothalamus-Pituitary-Testes-Axis (HPTA) shutdown by keeping the leydig cells producing testosterone at maximum capacity. This makes the transition into PCT smooth and allows for fast recovery.Post CT is a much safer alternative to HCG because using HCG will actually inhibit your natural testosterone production. HCG inhibits your own testosterone production due to the negative feedback loop it sends to the pituitary gland and hypothalamus. HCG usage will actually shut you down and PREVENT
recovery when used in a PCT. Post CT does the same thing as HCG, but without any of the nasty side effects.
