What is in this vial
All 2 brands of HCG here come in the same 5000 IU vial, so the choice between them is a choice of manufacturer and price, not of quantity. The powder has no concentration of its own: it is set when you add the water. This vial with 5 ml of bacteriostatic water gives 1000 IU per millilitre, and with twice that volume, half as much.
The conversion of an amount into insulin syringe units is worked through in the guide on syringe units, and the rules that change once the powder is dissolved are in storage.
Bio-Peptide as the manufacturer
Bio-Peptide has the widest catalogue of the three brands we stock: it is the only one supplying glutathione, NAD+, GHK-Cu, MOTS-C, SLU-PP-332 and semaglutide, so an order from this manufacturer can usually be filled from one supplier. Every vial carries a code under the hologram and a batch certificate, and how to check both is described on the verification page.
What the evidence says
It is the active substance of registered prescription medicines, and the 2026 World Anti-Doping Agency list names it explicitly in section S2.2.1 for men. The full account, with the sources and the limits, is on the HCG page, and the background in the guide on the legal status of peptides.
We publish no dosing schedules. Sold as research material, not as a medicine.
HCG is the one product in this catalogue measured in international units rather than milligrams, because that is how the registered medicines containing it are dosed as well. Bio-Peptide and Genheal both fill 5000 IU, so the choice here is the manufacturer.
Concentration in this vial
| Water added | Concentration | Per unit on a U-100 syringe |
|---|---|---|
| 5 ml | 1000 IU/ml | 10 IU |
| 10 ml | 500 IU/ml | 5 IU |
| 20 ml | 250 IU/ml | 2.5 IU |
The table is arithmetic and nothing else: it converts the 5000 IU in this vial into the concentration you get for a chosen volume of bacteriostatic water. It is not a dosing recommendation, and we publish none.
This vial next to the other HCG vials
The same compound is sold here in one other version: Genheal, 5000 IU. The molecule is identical in each; what differs is the manufacturer and the amount in the vial. All 2 hold the same amount, so the choice here is the manufacturer and its batch certificate, not the size.
