Featured peptide dosage protocols
The most requested protocols — each covers dosing schedules, reconstitution math and syringe draw volumes for every vial size.
Tirzepatide dosages
Dual GLP-1/GIP titration schedules with bacteriostatic water volumes and matching insulin-syringe units.
BPC-157 dosages
Tissue-support protocol with daily dosing schedules, concentration math and draw volumes per vial size.
Semaglutide dosages
Step-by-step weekly titration with reconstitution ratios for each vial strength.
Why our guides?
Most peptide protocols online come from forums, resellers or clinic marketing — no citations, no accountability. Every chart here is built from published research and verified reconstitution math, so you are working from data instead of guesswork.
- Figures drawn from published literature, not forum lore
- No clinic marketing or unsourced blog claims
- Straightforward reconstitution instructions
- Clear, consistent dosage breakdowns per vial size
- Reviewed and expanded as new research emerges
Every protocol includes
- Vial size
- Total peptide in the lyophilised vial, in mg or mcg.
- Bacteriostatic water
- Exact volume to add for the target concentration.
- Concentration
- mg or mcg per mL after reconstitution.
- Dose schedule
- Week-by-week titration where the research supports it.
- Syringe units
- U-100 insulin units to draw for each dose.
