How to use: Enter your vial size and the amount of bacteriostatic water you'll add. Then enter your desired dose to see exactly how much to draw.
Tip: 1 mL = 100 units on an insulin syringe. Draw slowly to ensure accuracy.
Reference Guide
Common Vial Sizes
Peptide Typical Size BPC-157 5mg, 10mg TB-500 5mg, 10mg Semaglutide 3mg, 5mg Ipamorelin 5mg, 10mg CJC-1295 2mg, 5mg Tirzepatide 5mg, 10mg, 15mg
Syringe Types
Size Units Best For 0.3mL 30 units Small doses, precision 0.5mL 50 units Most peptides 1mL 100 units Larger doses
Smaller syringes offer better precision for small doses. Use the smallest syringe that fits your dose.
Reconstitution Tips
Use bacteriostatic water (BAC) - contains 0.9% benzyl alcohol for preservation Inject water slowly - aim down the vial wall, not directly onto powder Never shake - gently swirl or roll the vial until dissolved Store properly - refrigerate at 2-8C after reconstitution Use within 28 days - most reconstituted peptides remain stable for about 4 weeks Keep sterile - always clean vial tops with alcohol before drawing
