HCG · Approved fertility medicine, misused for weight loss
A hormone with specific approvals — and an FDA warning about diet clinics.
Medically reviewed by Bernard Garcia, MD
What it is
Human chorionic gonadotropin (hCG) is FDA-approved for ovulation induction, certain cases of male hypogonadotropic hypogonadism and cryptorchidism. It is also used off-label alongside testosterone therapy to preserve fertility.
The FDA has stated plainly that hCG is not approved for weight loss and that "hCG diet" products are unproven; since 2020 hCG is regulated as a biologic, which restricted compounding.
How it works
hCG mimics luteinising hormone, stimulating the ovaries or testes. The approved uses are well characterised. Weight-loss use has been tested in controlled trials and found no better than placebo.
Research status
| Research area | Status |
|---|---|
| Ovulation induction / male hypogonadotropic hypogonadism | FDA-approved |
| Fertility preservation with testosterone therapy | Off-label · commonly discussed |
| Weight loss | Not approved · FDA warning · trials negative |
| Compounded hCG | Restricted since biologic transition (2020) |
Status reflects published research context only and is not a statement of safety, efficacy, or suitability for any person.
Is it legal?
hCG is FDA-approved for specific indications and is regulated as a biologic, which limits compounding. Weight-loss use is not approved and has been the subject of FDA warnings. This is a general note, not legal advice.
Frequently asked questions
Is the hCG diet real?
Controlled trials showed no benefit over placebo, and the FDA has warned against it.
Why do men on testosterone ask about it?
Because testosterone suppresses natural production and fertility; hCG is discussed off-label to counter that. A provider decides.
Is it a peptide?
It is a glycoprotein hormone — larger than a peptide, but often discussed in the same conversations.
