How It Works
Reconstitution is mixing a lyophilized (freeze-dried) peptide powder with bacteriostatic water to create an injectable solution.
Gather your vial
Note the amount of peptide in the vial (e.g. 5mg). This is printed on the label.
Add bacteriostatic water
Draw your chosen volume of bacteriostatic water into a syringe and inject slowly into the vial. Never shakeโswirl gently.
Calculate your draw
Use this calculator to determine exactly how many units to pull into your syringe for the desired dose.
Store properly
Reconstituted peptides typically require refrigeration (2โ8ยฐC) and are stable for 2โ4 weeks once mixed.
The Formula
Based on a standard 100-unit (1mL) insulin syringe. Each tick mark = 1 unit = 0.01mL.

Mix / Blend Reconstitution
Reconstitute a multi-peptide vial โ e.g. a "Glow" or "Recovery" blend. Add each peptide and the total water volume, then choose a draw amount to see per-peptide dosing.

How Blend Reconstitution Works
Multi-peptide blends are lyophilized (freeze-dried) together in a single vial. When reconstituted, every draw contains all peptides in the same ratio.
Know your vial contents
Check the label for each peptide and its amount in mg. A "Glow" vial might list GHK-Cu 3mg + Epithalon 5mg + Selank 2mg.
Add bacteriostatic water
Inject your chosen water volume into the vial. The total water volume determines concentration of all peptides simultaneously.
Draw your dose
Choose a draw amount (in syringe units). Because all peptides share the same solution, each draw delivers a fixed ratio of every peptide.
Verify the doses
Use this calculator to confirm each peptide's dose at your chosen draw volume, and adjust water volume or draw amount as needed.
