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.

Semaglutide Reference

Semaglutide Dosing Protocols

Goal	Dose	Frequency
Weight Loss Initiation	0.25mg	Weekly x 4 weeks, then increase
Weight Loss Maintenance	2.4mg	Weekly (after 16-week titration)
Diabetes Management	0.5-1mg	Weekly
Cardiovascular Protection	0.5-1mg	Weekly
Tolerability-Based	0.25-2.4mg	Weekly (individualized)

Reconstitution Steps

01 If using pre-filled pen, attach new needle and prime per instructions
02 If using vial, draw prescribed dose with appropriate syringe
03 Clean injection site with alcohol swab and let dry
04 Inject subcutaneously at 90-degree angle (45-degree if lean)
05 Hold for 6 seconds after injection to ensure full dose delivery
06 Dispose of needle safely and rotate injection sites weekly
