What is HCG?
Human chorionic gonadotropin is a glycoprotein hormone built from two non-identical subunits: an alpha chain shared with LH, FSH and TSH, and a beta chain unique to HCG. It is also heavily glycosylated, and those sugar chains are functional rather than decorative — they govern its stability and clearance, which is why it behaves quite differently from the short peptides in this catalogue.
It is supplied lyophilized and measured in international units. See the reconstitution guide and the reconstitution calculator for preparation.
Research context
In research models HCG is studied for its activity at the shared LH/HCG receptor and its role in gonadal-axis signalling, serving as a reference standard in reproductive-endocrinology study designs. Its structural similarity to LH is exactly what makes it useful as a stable, well-characterised stand-in.
Within the catalogue it sits closest to the other endocrine references — HGH as a pituitary-derived protein hormone, and the growth-hormone secretagogues in the growth-hormone research collection that act on a different axis entirely.
Purity and third-party testing
Every batch is independently analysed by Testides and Peptide Test Canada and ships with a certificate of analysis reporting HPLC purity and mass-spectrometry identity. See how to read a certificate of analysis and what a purity figure actually means, or read about our testing on the Research and Quality page.
Handling and storage
As a glycoprotein it is more fragile than a short peptide: keep it cold, reconstitute gently without shaking, and avoid repeated freeze-thaw, which degrades glycoproteins faster than simple sequences. The storage guide covers both states, and bacteriostatic vs. sterile water explains diluent choice — bacteriostatic water is stocked alongside.
