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.

Melanotan II Dosing Protocols

Goal	Dose	Frequency
Initial loading phase	0.25mg	1x daily
Tanning maintenance	0.5-1mg	2-3x weekly
Sexual enhancement	0.5-1mg	As needed
Minimal side effects	0.1-0.25mg	Every other day
Photoprotection	0.5mg	2x weekly

Reconstitution Steps

01 Clean vial tops with alcohol swab, let dry
02 Draw 2mL bacteriostatic water for 10mg vial (creates 5mg/mL)
03 Inject water slowly down vial side to avoid foaming
04 Gently roll vial - do not shake vigorously
05 Solution should be clear to slightly yellow
06 Wrap vial in foil (MT-II is light sensitive)
07 Store in refrigerator
08 Draw dose with insulin syringe (typical: 0.05-0.2mL)

Quick Reference

Typical Dose Loading: Start 0.25mg daily, increase to 0.5-1mg; Maintenance: 0.5-1mg 2-3x weekly

Frequency Loading phase: Daily for first week, then tanning maintenance 2-3x weekly or as needed for sexual enhancement

Half-life ~2 hours

Storage Refrigerate at 2-8°C wrapped in aluminum foil (light-sensitive); use reconstituted solution within 4 weeks

Cycle 4-8 weeks loading phase for tanning, then ongoing maintenance as needed
