Reconstitution Guide

Follow these steps to properly reconstitute your lyophilized peptide.

Gather Supplies

Peptide vial, bacteriostatic water, alcohol swabs, insulin syringe.

Clean Both Stoppers

Swab the rubber stoppers on both the peptide vial and BAC water vial with alcohol.

Draw BAC Water

Using a clean syringe, draw the desired amount of bacteriostatic water from the vial.

Inject Along the Wall

Insert the needle into the peptide vial and slowly release the water along the inside wall. Do NOT spray directly onto the powder.

Swirl Gently

Roll the vial gently between your fingers. Never shake — this can damage the peptide structure and reduce potency.

Wait for Full Dissolution

Allow the peptide to fully dissolve. This may take 1-5 minutes. The solution should be clear and colorless.

Store Properly

Refrigerate at 2-8°C immediately after reconstitution. Use within 21-30 days depending on the peptide.

Draw Your Dose

Use the Dose Calculator tab above to determine exactly how many insulin units to draw for your desired dose.

Important Notes

• Reconstituted peptides are stable for 4-8 weeks when refrigerated
• Always use bacteriostatic water (not sterile water) for multi-use vials
• Avoid repeated freeze-thaw cycles
• Use a new syringe for each withdrawal to maintain sterility
• Never mix different peptides in the same vial unless specifically directed
