Retatrutide Dose Escalation: The Phase 2 Protocol

All information here is drawn from published Phase 2 trial data and is for laboratory research reference only.

Dose Escalation Schedule

PhaseDoseDuration
Initiation2mg/weekWeeks 1-4
Escalation 14mg/weekWeeks 5-8
Escalation 28mg/weekWeeks 9+

The Phase 2 trial used this three-step escalation to minimize GI side effects during adaptation. Slower escalation is associated with significantly better GI tolerability.

Reconstitution Reference

CompoundVial SizeBAC WaterConcentration
Retatrutide10mg3.3mL3mg/mL
Retatrutide15mg5mL3mg/mL
Retatrutide30mg10mL3mg/mL
BPC-15710mg10mL1mg/mL
GHK-CU50mg10mL5mg/mL
SNAP-85mg5mL1mg/mL

Reconstitution procedure:

  • Let peptide vial reach room temperature
  • Clean vial top with alcohol swab
  • Inject BAC water slowly along the vial wall (not directly on powder)
  • Swirl gently — do NOT shake
  • Solution should be clear; if cloudy, do not use
  • Label with date and concentration
  • Store at 2-8°C
