What you need
- The lyophilised vial, at room temperature
- Bacteriostatic water (0.9% benzyl alcohol). Sterile water works too, but the solution then keeps for days rather than weeks
- A sterile syringe and needle
- Alcohol prep wipes
Method
- 01Wipe both stoppersSwab the peptide vial and the water vial. Let the alcohol dry; it needs contact time to work.
- 02Draw the waterPull the volume you have chosen into the syringe. 1–3ml is typical for a 10mg vial.
- 03Add it slowlyAngle the needle so the water runs down the inside of the glass rather than jetting onto the powder.
- 04Swirl, never shakeRoll the vial gently between your fingers until the powder disappears. Shaking foams the solution and denatures the peptide.
- 05Label itWrite the concentration and the date. Store at 2–8°C and use within 28 days.
Pre-mixed vials skip all of thishello lean and our single-compound vials arrive in solution. There is nothing to add; store them cold and they are ready.
Working out the concentration
Concentration is simply the mass in the vial divided by the water you add. The calculator below does the arithmetic for the volumes you are likely to use.

Concentration after reconstitution
Arithmetic only: mass divided by volume. It does not account for the small volume of the powder itself, which is negligible at these quantities.
