Getting Started With Peptides
How to mix, dose and store your peptides.
How to Mix Peptides
Peptides come as lyophilized (dry) powder in vials. Before use, they need to be reconstituted with bacteriostatic water. Wash your hands thoroughly and sanitize your workspace. Gather supplies: peptide vial, bacteriostatic water, sterile syringe, alcohol swabs.
Draw into Syringe
Draw bacteriostatic water into the syringe. The amount depends on your vial size and desired concentration.
Inject into peptide vial
Inject the water slowly into the peptide vial, letting it run against the side of the vial rather than directly onto the powder.
Swirl or roll vial in your hand
Gently swirl the vial to mix until fully dissolved. Do not shake vigorously, as this can damage the peptide.
Label the vial
Label the vial with the date of reconstitution. Keep a record of how many ml of water you mixed. Peptides stay good in the fridge for 30 days.
1. Select syringe size you have
2. Select the amount of mg of peptide in the vial
3. Select the amount of mL of water you will mix in
4. Select the dosage in mcg. 1000mcg = 1mg
Peptide Dosage Calculator
Interactive tool to convert your vial amount, reconstitution volume, and desired dose (mcg) into insulin syringe units (U-100). 1 mL = 100 units.
What is the total volume of your syringe?
U‑100 insulin syringes have unit scales that match the max volume: 0.3 mL → 30 units, 0.5 mL → 50 units, 1.0 mL → 100 units.
Select Peptide Vial Quantity
How much bacteriostatic water are you adding?
How much of the peptide do you want in each dose?
Notes: This calculator is for educational purposes. U‑100 insulin syringes have 100 units per mL (so each unit is 0.01 mL). Always follow your clinician's or research protocol guidance.
