Human Chorionic Gonadotropin (HCG) is a hormone naturally produced during pregnancy. In research settings, synthetic HCG is studied for its ability to mimic luteinizing hormone (LH), which stimulates the testes to produce testosterone and support fertility. HCG has a long history of medical use, but in most contexts outside of FDA-approved indications it is considered experimental. The 5000 IU vial size refers to the potency of the lyophilized powder prior to reconstitution.
How It Is Used in Research Settings
- Investigated for stimulating testosterone production in models of hypogonadism.
- Studied in fertility research for triggering ovulation in women and supporting spermatogenesis in men.
- Explored for maintaining testicular function during exogenous testosterone administration.
- Examined for metabolic effects in body composition and weight-related studies, though results remain controversial.
Proposed Uses (Research Areas)
- Male reproductive health and testosterone production research.
- Female fertility and ovulation induction studies.
- Testicular preservation during androgen therapy models.
- Body composition and weight regulation research (experimental).
How It Is Dosed in Research Settings
- Typical concentration: Supplied as a lyophilized powder in 5000 IU vials; reconstituted with bacteriostatic water before use.
- Injectable dosing: Research protocols commonly use 250–2000 IU subcutaneously or intramuscularly, administered 2–3 times per week.
- Cycle length: Varies based on study design, from several weeks to multiple months, depending on endpoints (testosterone, fertility, preservation of function).
- Handling: Once reconstituted, stored refrigerated and used within the stability period defined by the diluent and research SOPs.
Important Considerations
- Regulatory status: HCG is FDA-approved for specific medical indications (e.g., fertility treatment, hypogonadism). All other uses remain experimental.
- Evidence base: Supported by decades of clinical research in reproductive medicine; body composition and other applications remain unproven and experimental.
- Safety: Reported side effects include water retention, gynecomastia, mood changes, and injection site irritation. Long-term safety in off-label use is not established.
