HCG
HCG, or human chorionic gonadotropin, is a large glycoprotein hormone that activates the luteinizing-hormone/chorionic-gonadotropin receptor. It is used in reproductive-endocrine research and is structurally more complex than a short synthetic peptide.

HCG is currently being evaluated through customer voting and is not available to order. Final product specifications and batch documentation will be published only if it joins the catalogue.
This page records catalogue interest only. If HCG is selected for supply, Puffin will publish the confirmed format, batch documentation, and laboratory preparation information on the product listing.
Storage and handling requirements depend on the final supplied format. Confirmed instructions will be provided with the batch details if this candidate is added to the catalogue.
Understanding HCG
Explore the science, research focus, and key information behind this compound.
What is HCG?+
HCG is selected when a study needs a glycoprotein ligand for luteinizing-hormone receptor models.
What Researchers Study+
Researchers examine LH-receptor activity, Reproductive-endocrine signalling, and Gonadal-response models.
How HCG Works+
HCG mimics the receptor activity of luteinizing hormone, producing cyclic-AMP-dependent signalling in responsive gonadal cells. Its longer persistence is influenced by the beta subunit and glycosylation pattern.
Research at a Glance+
LH/CG-receptor biology is clinically validated. Approved HCG products and reproductive physiology provide strong human evidence for the receptor pathway. That evidence remains product-, dose-, and indication-specific. Glycosylation helps determine activity and persistence. Two HCG preparations can share an amino-acid sequence but differ in glycoforms, bioactivity, aggregation, and assay response. Functional testing is therefore central to comparability. HCG resembles LH activity but is not identical to LH. Both engage the LH/CG receptor, while glycosylation and molecular structure alter persistence and assay behaviour. Matched mass alone is not a fair comparison.
