HCG 10000IU: Reconstitution and Dosing Guide

Dosing Guide — 2026-10-02

The 10000IU HCG vial is the higher-capacity size, holding twice the units of a 5000IU vial — useful for longer research protocols or higher per-administration amounts. Human chorionic gonadotropin (HCG) arrives as a lyophilized powder and is reconstituted with bacteriostatic water before use. This guide covers the step-by-step, the concentration math for a 10000IU vial, and how many doses it provides. For laboratory research use only.

Platinum Biolabs ships every HCG vial with a batch-matched COA, from a US facility. Code PLATINUM25 takes 25% off your order at checkout.

What You Need

• Your HCG 10000IU vial (lyophilized powder)
• Bacteriostatic water for multi-use reconstitution
• A sterile transfer syringe and a U-100 insulin syringe
• Alcohol wipes

Step-by-Step

1. Bring the vial to room temperature; wipe the stopper with alcohol.
2. Draw your chosen volume of bacteriostatic water (see table).
3. Run the water slowly down the inside wall of the vial — do not squirt it onto the powder, as HCG is a delicate glycoprotein.
4. Do not shake. Swirl gently until the solution is clear.
5. Label and refrigerate right away.

Concentration and Dose Math

Because a 10000IU vial is twice as concentrated as a 5000IU vial at the same water volume, each syringe unit carries more IU. On a U-100 insulin syringe (100 units = 1 mL):

For small research amounts, adding 2 mL (50 IU/unit) gives easier-to-measure units than 1 mL (100 IU/unit). Pick the volume that lands your target amount on a readable number of units.

How Many Doses in a 10000IU Vial

That is double the 5000IU vial at every amount. Note, though, that once reconstituted the solution is generally used within about 30 days — so if you mix the whole vial at once, that window may limit you before the dose count does.

Storage After Reconstitution

• Refrigerate at 2–8°C at all times — reconstituted HCG is heat- and light-sensitive
• Use within ~30 days of reconstitution in bacteriostatic water
• No repeated freeze-thaw; many researchers reconstitute in portions to respect the window
• See the peptide storage guide

Bottom Line

Reconstitute a 10000IU HCG vial exactly like a 5000IU vial — water down the wall, swirl, refrigerate — but remember each unit carries twice the IU at the same volume. A 10000IU vial yields roughly 10–20 common research doses, subject to the ~30-day reconstituted window. For background, see HCG in research.
