Calculate precise reconstitution volumes and dosing for your research peptides. Select your vial size, add your bacteriostatic water volume, and get instant results.
Follow the steps below to calculate your precise mixing ratios.
Follow these steps for safe and accurate peptide reconstitution in your research.
Gather your peptide vial, bacteriostatic water, alcohol swabs, and an appropriate syringe. Ensure a clean workspace.
Draw your calculated BAC water volume. Inject slowly against the vial wall — never directly onto the powder. Let it dissolve gently.
Roll the vial between your palms — never shake. The solution should become clear. Store reconstituted peptides at 2-8°C.

Essential guidelines for handling and storing your research peptides.
Store unreconstituted peptides at -20°C for long-term. Once mixed, keep at 2-8°C (refrigerator) and use within 28 days.
Peptides are light-sensitive. Store in dark containers or wrap vials in foil. Minimise time outside of cold storage.
Always swab vial tops with alcohol before piercing. Use fresh needles for each draw to prevent contamination.
Mark each vial with the peptide name, reconstitution date, concentration, and expiry. Good lab practice prevents errors.
All ZENTRA peptides come with third-party COAs and are manufactured at GMP-compliant facilities.
