Approved drug — used here for education. This is an approved/prescription medicine in at least one region; "research"/compounded versions sold as chemicals are a separate, riskier thing. Not medical advice.
What it is
hCG (human chorionic gonadotropin) is a naturally occurring glycoprotein hormone that mimics luteinizing hormone (LH).
Proposed mechanism
It stimulates gonadal function — in males, testicular testosterone production; used in fertility and certain endocrine settings.1 (The "hCG diet" for weight loss is not supported and the FDA has warned against it.)
State of the evidence
Approved for specific fertility/endocrine indications; weight-loss claims are disproven.
Regulatory & status
FDA-approved (prescription) for defined indications; weight-loss use warned against.
Reconstitution (reference only)
