Reconstitution — step by step
- 1Let the powder vial and the bacteriostatic water reach room temperature first.
- 2Wipe both rubber stoppers with a fresh alcohol swab.
- 3Draw 2 ml of water and inject it slowly down the glass wall of the vial — don't aim straight at the powder.
- 4Gently swirl the vial until everything is fully dissolved. Don't shake — it foams and can damage the peptide.
- 5Draw your dose up to 50.0 units and store the vial refrigerated (2–8 °C), away from light.
Once reconstituted, most peptides keep for roughly 3–4 weeks refrigerated. Always check the label of the specific product.
