What is the total volume of your syringe?

💡 This is just the total capacity of your syringe — it does not affect your dosage. As long as your syringe can hold enough for your dose, any size works. Most people use a 0.5 ml or 1.0 ml insulin syringe.

How much bacteriostatic water are you adding?

💡 Most peptide vials are 3 ml vials, and most people add 3 ml of bacteriostatic water — but always double-check your vial size and instructions. More water = more diluted = easier to measure small doses.

Select Peptide Vial Quantity

💡 This is the total amount of peptide in your vial — check the label on your vial. Common sizes are 5 mg, 10 mg, or 15 mg. Some newer peptides come in 50 mg or 100 mg vials.

How much Peptide do you want in each dose?

💡 This is how much peptide you want per injection. Your protocol or provider will tell you how much to take. Most peptide doses are measured in mcg (micrograms). Remember: 1,000 mcg = 1 mg.

To have a dose of 0.5 mg, pull the syringe to 30 units (0.300 ml)

Concentration: 5 mg / 1 ml = 5,000 mcg/ml • Total doses in vial: 100
