How to reconstitute
1
Prepare
Let the vial reach room temperature. Wipe both the peptide and bacteriostatic water stoppers with an alcohol swab.
2
Add water slowly
Draw your chosen volume of bacteriostatic water and release it down the inside glass wall — never jet it onto the powder.
3
Swirl, then store
Swirl gently until fully clear. Never shake. Label with the date and refrigerate at 2–8°C, protected from light.
Frequently Asked Questions
- Lyophilised (freeze-dried) peptides arrive as a powder. Reconstitution is the step where you add bacteriostatic water to the vial to dissolve the powder into a measurable liquid. The amount of water you add sets the concentration — it does not change how much peptide is in the vial.
