HCG Research Overview

Human Chorionic Gonadotropin is a glycoprotein hormone produced during pregnancy by the syncytiotrophoblast cells of the placenta. It is the same active ingredient in pharmaceutical Pregnyl, Novarel and Ovidrel.

Purity and Laboratory Testing

Lot AFL-HCG-5-2026-001 (tested 2026-04-09) of HCG was assayed by an independent laboratory using reversed-phase HPLC for purity and mass spectrometry for identity confirmation, returning 99.3% purity. The Certificate of Analysis shipped in the box matches the lot number printed on the vial.

Technical Product Information

Molecular formula C₁₁₀₅H₁₇₇₀N₃₁₈O₃₃₆S₂₆ (approximate), molecular weight ~36,700 g/mol, sequence Glycoprotein heterodimer (α: 92 aa, β: 145 aa). HCG's beta-subunit closely mimics LH and binds the LH/CG receptor on Leydig cells (in males) or theca/granulosa cells (in females). The result is sustained downstream steroidogenesis — testosterone production in males, ovulation triggering in females. HCG is supplied as lyophilized powder and is classified in our catalog under glycoprotein hormone for glycoprotein hormone work. Recorded research categories for this compound include ovulation induction research, male fertility and testicular function research, post-cycle hpg axis restart studies, leydig cell pharmacology. Handling notes: store at 2-8°c (refrigerator), protect the vial from light, and avoid repeated freeze–thaw cycles once reconstituted. Amino Fuel Labs publishes no dosing protocol for HCG: the compound is distributed for in-vitro and preclinical laboratory research only and is not intended for human or veterinary use.

Frequently Asked Questions

Why is HCG used in post-cycle research?

HCG directly stimulates Leydig cells to restart testosterone production — bypassing the suppressed HPG axis. It's the fastest way to restore testicular function in published restart protocols.

Is HCG the same as 'HCG diet' drops?

No. Pharmaceutical and research HCG is an injectable glycoprotein. Homeopathic 'HCG drops' marketed for weight loss are unrelated and contain no measurable HCG.

How is HCG stored?

Lyophilized vials should be refrigerated (2-8°C). Once reconstituted, refrigerate and use within 30 days.

What is HCG studied for?

HCG appears in laboratory research covering fertility treatment, testosterone stimulation, ovulation induction. All references describe in-vitro and preclinical study models only.

Does HCG include a Certificate of Analysis?

Yes. Each HCG lot ships with a batch-specific third-party Certificate of Analysis reporting 99.3% purity by reversed-phase HPLC alongside mass-spectrometry identity confirmation.

What form does HCG arrive in?

HCG is supplied as lyophilized powder in a sealed vial, packed with the lot documentation for the exact batch shipped.
