How to reconstitute a peptide
- 01Bring the lyophilized (freeze-dried) peptide vial and bacteriostatic water to room temperature.
- 02Draw your chosen volume of bacteriostatic water and inject it slowly down the inside wall of the vial — never directly onto the powder.
- 03Swirl gently to dissolve; do not shake. Let it settle until clear.
- 04Store reconstituted peptide refrigerated and use within the window your provider specifies.
