How Long Does a 5000IU HCG Vial Last?

Buying Guide — 2026-10-03

"How long does a 5000IU HCG vial last?" is a practical pre-purchase question — it tells you how many vials a research protocol needs and what the real cost will be. The answer depends on the research amount per administration and how long the reconstituted solution stays stable. Here is the math. 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.

Doses Per Vial

A 5000IU vial holds 5000 international units total. Divide by the amount per administration:

Many research protocols administer two or three times per week, so a 5000IU vial at 500 IU per administration covers several weeks. For the concentration and syringe-unit math, see HCG 5000IU reconstitution and dosing.

How Long Once Reconstituted

This is usually the limiting factor, not the dose count. Reconstituted HCG is more fragile than many peptides:

• Refrigerated (2–8°C): generally used within about 30 days of reconstitution
• Bacteriostatic water (not sterile water) is what allows multi-use over that window
• Keep it cold, capped, out of light; avoid repeated freeze-thaw

So even if the dose math says a vial could last longer, the ~30-day reconstituted window often sets the practical limit. Reconstitute only what you will use in that time, or plan amounts accordingly.

Dry Storage Before Reconstitution

• Store the lyophilized powder cold (2–8°C) and sealed until use
• In dry form it is stable far longer than the reconstituted solution
• See the full peptide storage guide

Does the 10000IU Vial Last Longer?

Yes — a 10000IU vial holds twice the units and gives twice the doses, but the same ~30-day reconstituted window still applies once mixed. If you reconstitute the whole thing at once, the window — not the unit count — may govern. Many researchers reconstitute in portions to work around this.

Bottom Line

A 5000IU HCG vial provides roughly 5–20 research doses depending on the amount per administration, but the ~30-day reconstituted shelf life often sets the real limit. Map both your total IU and your timeline before buying. For background, see HCG in research.
