How do I reconstitute peptides with bacteriostatic water?

Draw bacteriostatic water into a syringe, inject slowly down the vial wall (not directly onto powder), then gently swirl until dissolved. Never shake. Store refrigerated at 2-8C and use within 28 days.

How many units should I draw on an insulin syringe?

1 mL equals 100 units on a standard insulin syringe. Divide your required volume in mL by 0.01 to get units. For example, 0.25 mL = 25 units. Use the smallest syringe that fits your dose for better precision.

What syringe size should I use for peptide injections?

0.3 mL (30 unit) syringes offer the best precision for small doses under 0.3 mL. 0.5 mL (50 unit) syringes work for most peptides. 1 mL (100 unit) syringes are needed for larger dose volumes.
