HCG Reconstitution Mistakes to Avoid

Dosing Guide — 2026-11-12

HCG is more sensitive than most research compounds — it's heat-sensitive, easy to mis-measure because of the IU-to-units conversion, and degrades faster once mixed. Most problems trace back to a handful of avoidable reconstitution mistakes. This guide walks through each one and the correct way to mix and store HCG. For the standard procedure, see the HCG reconstitution and dosing guide.

Mistake 1: Wrong water volume

The volume you add sets your per-unit dose. The standard is 2 mL bacteriostatic water for both the 5000iu and 10000iu vials:

Add a different volume and every dose you draw afterward is off. If you want both vials to read the same units, mix the 10000iu with 4 mL instead. See the HCG dosage chart.

Mistake 2: Shaking the vial

HCG is a protein — shaking can damage it. Add the bac water slowly down the inside wall of the vial, then swirl gently until dissolved. Never shake.

Mistake 3: Injecting water straight onto the powder

Aim the stream of bac water at the glass wall, not directly onto the lyophilized powder. A hard stream onto the powder can degrade it. Let it dissolve passively, swirling gently.

Mistake 4: Heat exposure

HCG is heat-sensitive. Common errors:

• Leaving the vial out at room temperature too long
• Storing it in a warm room instead of the fridge
• Letting it sit in a hot car during transport

Refrigerate before and after reconstitution. See HCG storage and shelf life.

Mistake 5: Mixing too much at once

Reconstituted HCG keeps only ~30 days refrigerated. Mixing a long run's worth at once means it degrades before you use it. Reconstitute one vial at a time.

Mistake 6: IU-to-units confusion

The single most common dosing error is confusing international units (IU) — the dose — with syringe units on a U-100 needle. After mixing a 5000iu vial with 2 mL: 10 units = 250 IU, 20 units = 500 IU. Don't dose "10" assuming it means 10 IU. The full conversion is in the HCG dosage chart.

The correct procedure in short

1. Bring vial and bac water to room temp.
2. Swab both stoppers.
3. Draw 2 mL bac water; inject slowly down the glass wall.
4. Swirl gently — never shake.
5. Refrigerate; use within 30 days.
6. Dose by units, using the chart. One bac water vial covers it.
