Which vendors sell hCG with independent COA testing?

9 vendors in the Merit Verified directory have independent COA evidence on file for hCG — 25 COAs total. COA coverage and test dates are listed on the hCG page at https://meritverified.org/peptides/hcg.

How do I verify the quality of hCG from a vendor?

To verify hCG quality, look for an independent certificate of analysis (COA) from a third-party lab — not a lab the vendor owns or pays directly. The COA should state the tested compound, lot number, purity percentage (identity and concentration), and the lab's name. Cross-reference the lot number against the vendor's current stock. Merit Verified indexes COAs for hCG at https://meritverified.org/peptides/hcg so you can compare evidence across vendors before buying.

What is the regulatory status of hCG?

hCG is tracked in the Merit Verified registry. Regulatory status for research peptides in the US has been evolving — the FDA has reclassified a number of peptides out of the 503A compounding ingredient list since 2025. Merit Verified does not provide legal or regulatory advice; check official FDA sources or consult a licensed professional for the current status of hCG in your jurisdiction.

hCG

Also known as: Human Chorionic Gonadotropin, Chorionic Gonadotropin, Pregnyl, Novarel, Ovidrel

FDA approved

Human chorionic gonadotropin is a placental glycoprotein hormone composed of a 92-amino-acid alpha subunit (shared with LH, FSH, and TSH) and a distinct 145-amino-acid beta subunit, joined non-covalently and heavily glycosylated. It acts as an agonist at the luteinizing hormone/choriogonadotropin receptor (LHCGR), mimicking the LH surge. In females it sustains the corpus luteum and progesterone production in early pregnancy and triggers final oocyte maturation and ovulation; in males it stimulates testicular Leydig cells to produce intratesticular testosterone, supporting spermatogenesis. hCG is FDA-approved (e.g., Pregnyl, Novarel, recombinant Ovidrel) for ovulation induction, assisted reproduction, and male hypogonadism/cryptorchidism.

Typical dose range

Fertility (final oocyte maturation): single 5,000-10,000 IU intramuscular or subcutaneous. Male TRT adjunct: commonly 250-500 IU subcutaneous 2-3x weekly (protocols vary, up to ~1,500 IU)

Half-life

~24-36 hours terminal half-life after IM/SC injection (biphasic; longer than LH due to glycosylation)

Common research uses

ovulation induction in assisted reproduction (IVF/IUI)male hypogonadism and restoring/maintaining fertility during testosterone replacement therapyprevention of testicular atrophy on TRTtreatment of cryptorchidism in boys

Safety notes

FDA-approved prescription drug; prescription-only in the US. Risks include ovarian hyperstimulation syndrome (OHSS) in women, thromboembolism, gynecomastia and fluid retention in men, and injection-site reactions. hCG is prohibited in men at all times under the WADA Code (S2 peptide hormones); homeopathic/weight-loss hCG products are not FDA-approved and are considered illegal/fraudulent.

Reconstitution

Lyophilized urinary hCG is reconstituted with the supplied bacteriostatic diluent; refrigerate after reconstitution and use within the labeled window. Recombinant hCG (Ovidrel) is supplied prefilled.
