📖 How to Reconstitute Peptides

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