Not medical advice. HCG is a research compound. This guide does not provide dosing, diagnosis, therapy recommendations, or claims about effects in humans.
HCG is listed in our catalogue under “Hormone / Fertility.” In scientific publications it is discussed in technical language; this page translates the general themes into everyday wording while staying faithful to research-only framing.
One-paragraph overview from our research datasheet — still scientific, but faster to read than the full mechanism list below.
HCG glycoprotein hormone (α/β heterodimer, 37.9 kDa) activates LHCGR receptor via PKA/PKC/Smad2 cascades for gonadal steroidogenesis and fertility support.
Peer-reviewed literature typically discusses HCG in specific experimental settings. The points below reflect how the scientific community frames this compound—not as health claims, but as the research questions being asked.
Research vs. personal use: Literature describes experiments in controlled lab and animal models. This is distinct from any real-world use; our products are for laboratory research only.
Compounds in this family are frequently studied in models of tissue injury, wound closure, and how cells reorganise after damage. Research looks at cell movement, blood-vessel support, and inflammatory balance -not at replacing medical care.
Our datasheet lists mechanistic themes observed in preclinical work. These are research endpoints, not health claims. They help scientists understand and compare pathways.
Storage requirements: Lyophilised powder: store in freezer (−20 °C). Reconstituted: refrigerate 1–6 °C, away from sunlight. Use within the validated stability window for the specific batch and formulation. · Learn best practices in our detailed storage guide.
Research dosing context: Literature typically discusses 250-10,000 IU depending on indication · Variable: single dose (IVF trigger), 2-3 times weekly (hypogonadism), as directed · Terminal t½ ~45 hours (substantially longer than LH). Apparent CL/F ~0.5 L/h; Vz/F ~30 L. SC bioavailability reduced in obese individuals. 1 IU = 1.68 μg pure peptide. Renally cleared; urinary hCG basis of pregnancy tests. Eight carbohydrate chains comprise 30% of molecular weight.
Preparation steps: Follow our detailed reconstitution guide, use the calculator tool for volume confirmation, and always verify purity with the COA reading guide.
Like all gonadotropins, hCG is calibrated against an international biological potency standard rather than by mass. One IU corresponds to approximately 1.68 μg of pure peptide. This convention is preserved in research protocols because it directly tracks bioactivity rather than weight, which can vary with glycosylation pattern.
hCG and LH share the same alpha subunit and act on the same receptor (LHCGR). The unique beta subunit gives hCG additional carbohydrate chains and a much longer circulating half-life (~45 h vs minutes for LH), which is why hCG is preferred as a research tool for sustained receptor activation.
Keep the lyophilised glycoprotein at −20 °C in the freezer. After reconstitution, refrigerate at 2-8 °C and protect from light. Avoid vigorous shaking and repeated freeze-thaw cycles, which can damage the heavily glycosylated structure.
