How to Reconstitute Peptides
Step-by-step guide for proper reconstitution
Gather Your Supplies
You will need: peptide vial, bacteriostatic water (BAC water), alcohol swabs, and a sterile syringe.
Clean the Vial Tops
Wipe the rubber stopper of both the peptide vial and the bacteriostatic water vial with an alcohol swab. Allow to dry.
Draw the Bacteriostatic Water
Using a sterile syringe, draw your desired amount of bacteriostatic water (typically 1-2 mL for most peptides).
Add Water Slowly
Insert the needle into the peptide vial and slowly release the water down the inside wall of the vial. Do NOT spray directly onto the powder as this can damage the peptide.
Allow to Dissolve
Let the vial sit for a few minutes. The peptide will dissolve on its own. Never shake the vial - gentle swirling is acceptable if needed.
Ready for Use
Once fully dissolved (solution should be clear), your peptide is ready. Use the calculator above to determine your dosing.
Peptide Storage Guide
Proper storage ensures peptide stability and potency
Unreconstituted (Powder)
- Freezer (-20°C): Stable for 2+ years
- Refrigerator (2-8°C): Stable for 6-12 months
- Room temperature: Stable for several weeks
- Keep away from light and moisture
Reconstituted (Mixed)
- Refrigerator (2-8°C): Use within 4-6 weeks
- Freezer (-20°C): Can extend shelf life
- Never leave at room temperature
- Avoid repeated freeze-thaw cycles
