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.

Survodutide Dosing Protocols

Goal	Dose	Frequency
Obesity - Conservative Start	0.6mg titrated over 24 weeks	Once weekly with 4-week intervals

Reconstitution Steps

01 Remove vial from refrigerator; allow 15-30 minutes to reach room temperature
02 Clean rubber stoppers with alcohol swabs
03 Draw prescribed amount of bacteriostatic water
04 Insert needle at 45-degree angle into vial
05 Inject BAC water down vial side slowly to minimize foaming
06 Gently swirl (do not shake vigorously)
07 Allow 2-3 minutes for complete dissolution
08 Solution should be clear to slightly opalescent without particles
09 Store reconstituted solution in refrigerator immediately
