HCG 5000IU — Human Chorionic Gonadotropin
HCG is human chorionic gonadotropin, a glycoprotein hormone built from two non-covalently associated subunits — an alpha subunit shared with other glycoprotein hormones and a beta subunit specific to HCG. Because it is a glycoprotein rather than a simple synthetic peptide, its quantity is expressed in International Units of biological activity rather than in milligrams.
Compound data
| Compound | Human chorionic gonadotropin (HCG) |
| Class | Glycoprotein hormone, alpha/beta heterodimer |
| Quantity unit | International Units (IU) — activity, not mass |
| Note | IU cannot be converted to mg without a substance-specific factor |
| Appearance | White lyophilized powder |
| Solubility | Water soluble |
| Quantity | 5000 IU per vial |
| Purity | 99%+, verified by HPLC and mass spectrometry |
| Presentation | Lyophilized powder, sealed vial |
Storage and handling
- Dry powder: store at −20 °C, sealed, protected from light and moisture.
- Bring the sealed vial to room temperature before opening — lyophilized powder is hygroscopic and draws moisture onto a cold surface.
- After reconstitution: refrigerate at 2-8 °C, protect from light, and avoid repeated freeze-thaw cycles.
What you need to reconstitute it
Material is supplied dry and has to be brought into solution before use. Bacteriostatic Water 20 mL is the standard solvent and is sold separately — step-by-step procedure in the reconstitution guide, and a comparison of solvents in bacteriostatic water vs sterile water.
Documentation
Every batch is third-party tested: HPLC for chromatographic purity, mass spectrometry for identity. New to batch documents? See how to read a COA, what 99% purity actually means and net peptide content vs gross weight and the full glossary entry on IU vs mg.
