Retatrutide Mixing & Dosage Protocols

(Triple GLP-1 / GIP / Glucagon Receptor Agonist for Metabolic & Weight-Loss Research)

Reconstitution (Mixing)

  • Add 3 ml Bacteriostatic Water to the vial.
  • Roll gently between your palms (do not shake).
  • Store in the refrigerator after mixing.

Concentration Calculation

30 mg ÷ 3 ml = 10 mg per ml

Every 10 units (0.1 ml) = 1 mg Retatrutide 

Dosage Guidelines

For metabolic enhancement, glucose regulation, and fat-reduction research:

  • Start: 1 mg (10 units) once per week to assess tolerance
  • Titration:
    • Weeks 3–4 → 2 mg (20 units) weekly
    • Weeks 5–6 → 4 mg (40 units) weekly
    • Weeks 7+ → 6 mg (60 units) weekly or as tolerated
  • Administration: Subcutaneous injection (abdomen, thigh, or upper arm)
  • Frequency: Once weekly on the same day each week

Biopeptics recommendation:

Always start by assessing tolerance with a micro-dose of 1 mg, and stay on the lowest effective dose for as long as possible. Some individuals may not need to increase their dosage at all - only adjust the dose if truly necessary, and do so in very small increments.

Key Benefits:

  • Potent triple-pathway action on GLP-1 / GIP / Glucagon receptors
  • Enhances energy expenditure, fat oxidation, and metabolic flexibility
  • Improves appetite control and glucose homeostasis
  • Supports cardiovascular health and lean-mass preservation

Maintenance: Continue weekly dosing at the lowest effective level for ongoing metabolic support.

Important Notes

  • Always use sterile needles and alcohol swabs.
  • Do not reuse or share needles.
  • Store reconstituted vial in the refrigerator (2 – 8 °C).
  • For research use only.
  • Possible transient effects: mild nausea, headache, fatigue, or injection-site redness.
