HCG is a glycoprotein hormone that mimics luteinizing hormone (LH) through shared receptor binding. Research uses include studies of Leydig cell steroidogenesis, testosterone biosynthesis pathways, gonadotropin receptor signaling, and male reproductive endocrinology in laboratory settings.
HCG binds to LH/hCG receptors on testicular Leydig cells, activating the cAMP/PKA signaling cascade that stimulates StAR protein expression and the steroidogenic enzyme pathway (CYP11A1, CYP17A1, HSD17B3), ultimately converting cholesterol to testosterone in research models.
Yes — every HCG order from AscendLabz includes a Certificate of Analysis confirming identity, purity, and potency for complete research documentation and batch traceability.
HCG is a human chorionic gonadotropin glycoprotein with LH-receptor binding activity studied as part of the glycoprotein hormone research category. It is investigated in pre-clinical and in-vitro research models for its activity on LH/CG receptor signaling and steroidogenic pathways studied in vitro. The compound is supplied as a lyophilized powder of ≥99% HPLC-verified purity and is intended exclusively for laboratory research use under qualified scientific supervision.
AscendLabz HCG is sourced from cGMP-aligned synthesis facilities and validated for identity, purity, and counter-ion content prior to release. Each lot is independently tested by HPLC, and a Certificate of Analysis (COA) detailing peak area, retention time, and batch number is provided with every order. This level of documentation is intended to support reproducible research and clear chain-of-custody record-keeping in academic and independent laboratory environments.
For research workflows, HCG is most commonly characterized in cell-culture and isolated-tissue models where investigators examine LH/CG receptor activation alongside complementary compounds in the gonadotropin research compounds class. Reference standards and dose-response controls should be established by each laboratory prior to experimental use, and all material should be handled by trained personnel using appropriate personal protective equipment.
Storage: Lyophilized HCG is stable at 2-8°C. Reconstituted solutions must be refrigerated and used within 30 days. Do not freeze reconstituted product. Lyophilized peptides should be kept in original sealed packaging until use to prevent moisture uptake.
Reconstitution: Bring the lyophilized vial to room temperature before opening. Reconstitute with bacteriostatic water by injecting solvent down the inner wall of the vial; do not direct the stream onto the lyophilized cake. Gently swirl — do not vortex or shake — until fully dissolved. Allow 5-10 minutes for complete solvation.
Handling: Use sterile technique throughout. Wipe vial septa with isopropyl alcohol before each draw. Document reconstitution date, solvent volume, and resulting concentration on the vial label for traceability.
Every batch of HCG is analyzed by reverse-phase HPLC and confirmed to be ≥99% pure. Mass spectrometry confirms molecular identity, and counter-ion / residual-solvent panels are performed where applicable. The full Certificate of Analysis ships with each order and is also archived by lot number.
No. HCG is supplied strictly for in-vitro laboratory research and is not approved by the FDA, EMA, or any regulatory authority for human or veterinary therapeutic use. It must not be administered to humans or animals. By purchasing, you confirm you are a qualified researcher and the material will be used only in a controlled laboratory setting.
All orders ship from the USA via tracked courier within 24-48 hours of payment confirmation. Domestic delivery typically arrives within 2-5 business days in discreet, temperature-stable packaging. Tracking is provided by email at the time of dispatch.
