HCG (5000 IU)

What is HCG?

Mimics LH — the brain signal that tells the testes to produce testosterone.

Listed vial contents: 5000 IU. These are supplied quantities, not administration doses. Current pricing and availability are shown in the strength selector.

What mechanisms are being studied?

Human Chorionic Gonadotropin is a 237-amino acid glycoprotein that binds LH/CG receptors on testicular Leydig cells, mimicking luteinizing hormone (LH) signaling. It stimulates testosterone production, maintains testicular volume, and supports spermatogenesis. Half-life of 24-36 hours.

What are the research questions?

• Hypogonadism / TRT adjunct: Maintains testicular function and fertility during testosterone replacement therapy. Prevents testicular atrophy.
• Male infertility: Directly stimulates testosterone production and spermatogenesis. FDA-approved for this indication.
• Cryptorchidism (pediatric): FDA-approved for undescended testes in prepubertal males.
• Female fertility (ovulation induction): Used as an ovulation trigger in IVF and fertility protocols.

What does the published work describe?

Coviello AD et al. (JCEM 2008) — Reliable 200-300% testosterone elevation. FDA-approved for multiple indications with decades of clinical data. Extensive use in fertility medicine worldwide.

What are the limits of this evidence?

The research described concerns the cited experimental materials and models, not proof that this supplied vial is a treatment. Cell or animal findings do not establish human benefits. Clinical findings, where cited, apply to the tested formulation and population; they do not validate this research product for human use.
