HCG

HCG is a glycoprotein gonadotropin composed of alpha and beta subunits, structurally related to luteinizing hormone (LH). It is catalogued here as a laboratory reference material for controlled endocrine-pathway and receptor-signalling research. It is supplied strictly for laboratory research use — not for human or veterinary use.

Published laboratory research examines HCG as an LH/CG receptor agonist: receptor binding and activation dynamics, downstream cAMP signalling, steroidogenesis-related endpoints in cell and tissue models, and hypothalamic-pituitary-gonadal axis pathway interrogation. These are experimental measurements in research models only; no medical, therapeutic, or human-use outcome is described or implied.

HCG acts directly at the LH/CG receptor as an agonist, while gonadorelin is a synthetic GnRH analog studied at the upstream pituitary level of the same axis. They are distinct research materials interrogating different points of the pathway, and each is listed separately in the catalog.

A third-party analytical report from Janoshik Analytical covering HCG 10kIU (June 2026) is on file. You can search batch-level documentation in the public COA lookup, and the transparency page explains the identity, purity, and documentation framework applied to every batch.

Each batch is tested against a ≥99% purity specification by HPLC with identity confirmation by mass spectrometry, consistent with the published testing standards. Batch documentation is released with orders and indexed in the COA lookup.

HCG is supplied as a lyophilized powder in sealed glass vials in 2000 IU, 5000 IU, and 10000 IU formats, each carrying a batch identifier that maps to its analytical documentation.

Store refrigerated, dry, and protected from light, and follow the batch documentation supplied with the vial. Orders ship domestically from the USA with tracked delivery. All material is intended strictly for controlled laboratory research.
