HCG – Human Chorionic Gonadotropin – is not a steroid. It’s a natural peptide hormone which develops in the placenta of pregnant women during pregnancy to controls the mother’s hormones.
When it comes to post cycle therapy, HCG is great as a precursor to post cycle therapy, as it reestablishes your testosterone production levels from the testicles.
During long steroid or prohormone cycles, it’s good to use HCG to maintain the size of your testicles or to recover from atrophied testicles. HCG is a natural stimulant to the Leydig cells in the testes, which releases androgen hormones, such as testosterone. HCG serves to that tells the Leydig cells to create more testosterone.
Men who are bodybuilders sometimes also use HCG with a very low-calorie diet to burn off that extra layer of fat over their muscles, giving them an extremely defined look. Women may also use HCG with a very low-calorie diet to burn off unwanted fat.
