Laboratory protocol
Reconstitution guide.
A sterile, repeatable protocol for bringing lyophilized research peptides into solution with bacteriostatic water.
This guide is for licensed laboratory researchers performing in-vitro research only. It is not a guide for human self-administration.

- 01
Preparation
Gather your peptide vial, sterile bacteriostatic water, sterile syringes and needles, alcohol prep pads, and a clean workspace. Ensure all equipment is sterile to prevent contamination.
- 02
Draw the water
Draw the volume of bacteriostatic water indicated by your calculation. Double-check the volume and remove any air bubbles, keeping the needle sterile.
- 03
Inject the water
Clean the rubber septum with an alcohol pad and let it dry. Inject the water slowly, aiming down the inside wall of the vial. Do not shake — let it run in gently, then remove the syringe.
- 04
Reconstitution time
Let the vial sit undisturbed for 5–10 minutes. Do not shake. The solution should become clear as the lyophilized powder fully dissolves.
- 05
Withdraw your aliquot
Clean the septum again and let it dry. Using a new sterile syringe, withdraw your calculated aliquot using the syringe markings. Double-check the volume. These are laboratory aliquot volumes for in-vitro research only — not human dosing instructions.
- 06
Storage
Store at 2–8°C in a cool, dark place with the septum intact. Reconstituted peptides are typically stable for ~30 days. Always use a fresh sterile needle, and label the vial with the reconstitution date.
Safety notes
- Always use sterile equipment.
- Use bacteriostatic water only — never tap or regular water.
- Be gentle; excessive shaking can denature peptides.
- Maintain proper temperature throughout.
- Use a fresh needle for every withdrawal.
- Follow your calculations — use the calculator for accurate aliquots.
