Product Overview
Human Chorionic Gonadotropin (HCG) is a glycoprotein hormone investigated in controlled laboratory environments for its interaction with the luteinizing hormone/choriogonadotropin receptor (LHCGR).
HCG is composed of alpha and beta subunits and is structurally related to other glycoprotein hormones. Research involving HCG includes receptor signaling, gonadal steroidogenesis, reproductive endocrinology, Leydig-cell biology, ovarian signaling, and hypothalamic-pituitary-gonadal axis research.
Unlike the synthetic peptides in much of the OPTMZ Peptides catalog, HCG is a glycoprotein hormone rather than a conventional short synthetic peptide.
| Label Specification | Measured Content | Purity |
|---|---|---|
| 1,000 IU | 1,066.56 IU | 99.70% |
| 2,000 IU | 2,127.01 IU | 99.78% |
| 5,000 IU | 5,372.33 IU | 99.70% |
| 10,000 IU | 10,605.14 IU | 99.64% |
These are the values shown directly on the supplied Waiida Test Report.
The submitted HCG product was evaluated by Waiida Testing Technology under Task Number #26044.
The report provides:
All four tested specifications therefore report >99.6% purity.
Important: This report does not show an endotoxin test or endotoxin result. For the website, I would classify endotoxin status for this HCG as Not Tested / Not Reported on Current COA, rather than Pass or Fail.
HCG should be handled by qualified professionals in controlled laboratory environments. Appropriate storage conditions should be maintained to preserve glycoprotein integrity and analytical consistency.
Avoid unnecessary exposure to heat, moisture, light, and repeated temperature fluctuations. Experimental preparation, storage, and handling should follow validated laboratory procedures appropriate to the intended research application.
Human Chorionic Gonadotropin is investigated extensively in reproductive and endocrine research.
Research areas include:
HCG interacts with the same receptor system as luteinizing hormone—the luteinizing hormone/choriogonadotropin receptor (LHCGR). This receptor interaction makes HCG an established experimental tool for investigating gonadal signaling and steroidogenic pathways.
These research contexts describe the scientific literature surrounding HCG and do not establish intended use of this particular research product in humans or animals.
HCG is relevant to experimental investigations involving reproductive endocrinology, LHCGR activation, gonadal steroidogenesis, Leydig-cell function, ovarian signaling, receptor-mediated cAMP signaling, and glycoprotein hormone biology.
Its established receptor pharmacology also makes HCG useful in comparative research involving luteinizing hormone, gonadotropin receptors, receptor activation, and downstream intracellular signaling.

Established Clinical Research HCG has an extensive experimental, biochemical, and clinical literature. This evidence classification describes the scientific evidence surrounding the HCG molecule, not the regulatory status or intended use of the OPTMZ research material.
Human Chorionic Gonadotropin is a heterodimeric glycoprotein hormone composed of noncovalently associated alpha (α) and beta (β) subunits. The alpha subunit is shared structurally with other glycoprotein hormones, while the beta subunit contributes to HCG-specific molecular recognition. HCG contains multiple glycosylation sites that contribute substantially to its molecular mass, structural properties, and biological behavior.
Heterodimeric glycoprotein composed of α- and β-subunits. Alpha subunit: approximately 92 amino acids. HCG-specific beta subunit: approximately 145 amino acids. For this ACF field, I recommend not inserting one long sequence string as though HCG were a conventional linear peptide. The α/β heterodimeric structure and glycosylation are scientifically important characteristics of the molecule.
