Peptide Reconstitution Guide
A quick reference for reconstituting lyophilized research peptides with bacteriostatic water.
What you need
The peptide vial, bacteriostatic water (BAC Water), an insulin syringe, and alcohol swabs. BAC Water contains 0.9% benzyl alcohol which inhibits microbial growth — do not substitute with sterile water for multi-use vials.
How to reconstitute peptides — step by step
- Wipe the rubber stopper on both the peptide vial and BAC Water vial with an alcohol swab.
- Draw the desired volume of BAC Water into the syringe (use the calculator above).
- Insert the needle into the peptide vial at an angle and let the BAC Water run down the side of the glass — do not inject directly onto the lyophilized powder.
- Gently swirl (do not shake) until the powder is fully dissolved. The solution should be clear.
- Store reconstituted peptides refrigerated at 2–8°C. Most compounds are stable for 4–6 weeks once reconstituted.
How the math works
If you add 2mL of BAC Water to a 10mg vial, you get a concentration of 5mg/mL (5,000mcg/mL). A 250mcg dose would then require 0.05mL (5 units on a 100-unit insulin syringe). The calculator above does this automatically for every compound we carry.
