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.

SNAP-8 Dosing Protocols

Goal	Dose	Frequency
Initial Phase (Weeks 1-4)	0.33mg (330mcg)	1x daily
Mid-Phase (Weeks 5-8)	0.5mg (500mcg)	1x daily
Target Phase (Weeks 9-12)	1.0mg (1000mcg)	1x daily

Reconstitution Steps

01 Allow vial to reach room temperature
02 Clean vial top with alcohol swab; allow to dry
03 Draw 3.0 mL bacteriostatic water into syringe
04 Inject water slowly down inside wall to minimize foaming
05 Gently swirl vial—do NOT shake vigorously
06 Allow complete dissolution (clear solution)
07 Final concentration: ~3.33 mg/mL
08 Store reconstituted solution at 2-8°C; use within 30 days
