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.

Mazdutide Dosing Protocols

Goal	Dose	Frequency
Weight loss initiation (3mg target)	1.5mg → 3mg	Once weekly
Weight loss progression (4.5mg target)	1.5mg → 3mg → 4.5mg	Once weekly
Weight loss optimization (6mg target)	2mg → 4mg → 6mg	Once weekly
Maximum weight loss (9mg target)	3mg → 6mg → 9mg	Once weekly
T2D management (mild-moderate)	3-4.5mg weekly	Once weekly

Reconstitution Steps

01 Allow vial to reach room temperature (15-20 minutes)
02 Clean vial top with alcohol swab, air dry completely
03 Calculate reconstitution volume for desired concentration
04 Draw bacteriostatic water into syringe, remove air bubbles
05 Inject BAC water slowly down vial side—drop by drop to prevent foaming
06 Gently swirl vial in circular motion
07 Verify complete clarity and colorless appearance
08 Label vial with reconstitution date and concentration
09 Store at 2-8°C, use within 30 days
