HCG (Human Chorionic Gonadotropin) 5000IU (HCG for PCT UK) by AASScripts is a pharmaceutical-grade peptide hormone widely used to stimulate the body’s natural testosterone production. It mimics the action of luteinizing hormone (LH), which signals the testes to produce testosterone — making it an essential part of both on-cycle support and post-cycle therapy (PCT) for steroid users.

HCG helps prevent testicular shrinkage, low libido, and infertility that can occur after long steroid cycles. It is particularly beneficial during PCT to kickstart the hypothalamic-pituitary-testicular axis (HPTA), ensuring faster hormonal recovery and preserving muscle gains.

Athletes and bodybuilders often use HCG either mid-cycle to maintain testicular function or after a cycle to restart testosterone production before introducing SERMs like Clomid or Nolvadex.
