Peptide Mixing & Dosage Instructions
A step-by-step guide to safely reconstituting lyophilized peptides. Always follow sterile technique.
Gather Supplies
You'll need: your peptide vial, bacteriostatic water (BAC water), an insulin syringe (typically 1mL/100 units), and alcohol swabs.
Clean the Vial Tops
Wipe the rubber stoppers of both the peptide vial and the bacteriostatic water vial with an alcohol swab. Allow to air dry.
Draw Bacteriostatic Water
Using your syringe, draw the appropriate amount of BAC water. For most 5mg peptides, 2mL of water is standard. This creates a concentration of 2.5mg/mL.
Inject into Peptide Vial
Slowly inject the BAC water into the peptide vial. Aim the stream against the glass wall, NOT directly onto the powder. Let it gently flow down the side.
Gently Swirl
Gently swirl (do NOT shake) the vial until the powder is fully dissolved. The solution should be clear. If particles remain, let it sit at room temperature for a few minutes.
Store Properly
Once reconstituted, store the vial in the refrigerator at 2-8°C. Most reconstituted peptides are stable for 14-21 days refrigerated. Never freeze reconstituted peptides.
Important Notes
- •Always use bacteriostatic water, not sterile water, for reconstitution — it contains preservatives that prevent bacterial growth.
- •Never shake the vial vigorously — this can damage the peptide structure.
- •Discard any solution that appears cloudy, discolored, or contains particles after reconstitution.
- •For research purposes only. Consult with a qualified professional before beginning any research protocol.
