Human Chorionic Gonadotropin (HCG) is used by bodybuilders to maintain natural testosterone production while on or after a steroid cycle.
It helps prevent testicular atrophy, supports muscle retention, and balances hormones during PCT (Post Cycle Therapy).
Typical doses range from 250-500 IU twice a week on cycle or 1,000-2,000 IU per week during PCT. Always combine with an AI (Aromatase Inhibitor) if needed to manage estrogen levels.
