📖 How to Reconstitute Peptides
- Clean everything — Wipe the vial tops with alcohol swabs
- Draw bacteriostatic water — Use a sterile syringe to draw your calculated amount
- Inject slowly — Add water to the peptide vial slowly, aiming at the glass wall (not directly on the powder)
- Gently swirl — Never shake! Gently roll the vial to dissolve the powder
- Refrigerate — Store reconstituted peptides at 36-46°F (2-8°C)
- Use within 4-6 weeks — Reconstituted peptides have limited stability
