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.

Cagrilintide Reference

Cagrilintide Dosing Protocols

Goal	Dose	Frequency
Weight Loss (Monotherapy)	2.4mg	Once weekly
Weight Loss (CagriSema)	2.4mg + semaglutide 2.4mg	Once weekly
Type 2 Diabetes Management	2.4mg weekly	Once weekly
Dose Escalation Protocol	0.25mg → 0.5mg → 1.0mg → 1.7mg → 2.4mg	Weekly increases over 16 weeks

Reconstitution Steps

01 CRITICAL: Requires acidic pH (3.5-4.5) to prevent fibril formation
02 Reconstitute slowly down vial side; swirl gently (do not shake)
03 Verify pH 3.5-4.5 after reconstitution
04 Solution must be clear—discard if cloudy or particulate
05 Store refrigerated (2-8°C); inspect before each injection
06 Allow 15-30 minutes to reach room temperature before injection
07 Rotate injection sites weekly
