HCG: Dosage, Benefits & Research Guide

Key Facts

HCG is a sexual wellness research peptide. Human chorionic gonadotropin (hCG) is a glycoprotein hormone studied for its luteinizing-hormone-like activity on gonadal tissue. For laboratory research use only. It is supplied as a lyophilized powder for laboratory and in-vitro research use only — not for human consumption.

What is HCG?

Human chorionic gonadotropin is a glycoprotein hormone that mimics luteinizing hormone by binding the LH/hCG receptor on Leydig and granulosa cells. In research settings it is used as a tool to study steroidogenesis, gonadal function, and the hypothalamic-pituitary-gonadal axis, including models of testosterone production and ovulation induction pathways. Because of its long half-life and potent receptor activity, it is a common reference agonist in reproductive endocrinology research. Supplied as a lyophilized powder for in-vitro and laboratory research use only; not for human or veterinary use.

HCG Research Applications

In published and preclinical research, HCG has been studied across the following areas:

LH/hCG receptor signaling research
Steroidogenesis and gonadal function studies
Reproductive endocrinology models
HPG-axis research

HCG in Research: Reconstitution & Study Concentrations

HCG is supplied as a lyophilized powder. For laboratory research it is reconstituted with bacteriostatic or sterile water; the solvent volume sets the working concentration. Published studies select concentrations specific to the assay or model system — there is no human dose, as HCG is not approved for human use. Researchers should reference the primary literature for the model in question and document the exact lot COA.

Worked example: a 10,000 IU vial reconstituted with 2 mL of bacteriostatic water yields 5000.00 mg/mL.

HCG — Frequently Asked Questions

What is HCG?

Human chorionic gonadotropin (hCG) is a glycoprotein hormone studied for its luteinizing-hormone-like activity on gonadal tissue. For laboratory research use only. It is supplied in 10,000 IU vials and intended strictly for in-vitro and laboratory research use only.

How should HCG be stored?

HCG should be stored at -20°C for long-term storage or 2-8°C for short-term use. Keep the vial sealed and protected from light, moisture, and repeated freeze-thaw cycles. Once reconstituted, store at 2-8°C and use within 30 days.

What purity is HCG?

HCG is manufactured to a minimum purity of ≥98% as verified by HPLC analysis, with identity confirmed by mass spectrometry. Each batch ships with a Certificate of Analysis (COA).

Is HCG legal to buy for research?

HCG is sold in the United States as a research chemical for laboratory and in-vitro use only. It is not approved by the FDA for human use and is not sold for human consumption. Researchers are responsible for compliance with all applicable federal, state, and institutional regulations.

How is HCG reconstituted for research use?

HCG ships as a lyophilized (freeze-dried) powder and is reconstituted with bacteriostatic or sterile water before use in research. The volume of solvent added determines the working concentration — use the Elyte reconstitution calculator to derive the exact concentration for a given vial size and solvent volume.

Does HCG come with a Certificate of Analysis?

Yes. Every batch of HCG from Elyte Peptides ships with a third-party Certificate of Analysis (COA) documenting identity and HPLC purity (≥98%), so research results can be traced to a verified lot.
