GMP-Certified, ≥98% HPLC-Verified
HCG (Human Chorionic Gonadotropin)
Wholesale Glycoprotein Hormone. HCG (Human Chorionic Gonadotropin) is a heterodimeric glycoprotein hormone, composed of a 92-amino-acid alpha subunit (shared structurally with LH, FSH, and TSH) and a distinct beta subunit of approximately 145-149 amino acids. It is widely researched in fertility, endocrine, and reproductive science.

Frequently asked questions
What is HCG?
HCG (Human Chorionic Gonadotropin) is a heterodimeric glycoprotein hormone, composed of a 92-amino-acid alpha subunit shared structurally with LH, FSH, and TSH, and a distinct beta subunit of approximately 145-149 amino acids. It is widely researched in fertility, endocrine, and reproductive science.
What is the difference between HCG and HMG?
HCG is a single glycoprotein hormone with its own distinct alpha and beta subunits. HMG (Human Menopausal Gonadotropin) is a combination preparation of two different hormones, FSH and LH, in a 1:1 ratio. Both are gonadotropins but are structurally and compositionally distinct.
What purity does Peptide Direct's HCG meet?
All HCG supplied by Peptide Direct is verified by HPLC analysis to a minimum purity of ≥98% on a batch-by-batch basis, with a Certificate of Analysis supplied on every order.
What strengths are available?
HCG is available wholesale in 5000 IU, with flexible minimum order quantities for bulk buyers. Contact us if you require other strengths.
Can I get HCG under my own brand?
Yes. Private label packaging, vials, and labelling are available for qualifying wholesale buyers. See our Private Label page for details.
How should HCG be stored?
Store refrigerated at 2–8°C, away from direct light. For long-term storage, freezing conditions are recommended prior to reconstitution.
Is HCG manufactured under GMP conditions?
Yes. All HCG supplied by Peptide Direct is manufactured under GMP and ISO 9001:2015 certified conditions, the same standard applied across our full compound range.
