What is Retatrutide?
Retatrutide is a research peptide in the GLP-1 Metabolic class. Triple agonist: GLP-1, GIP, and glucagon receptor. It is studied at per-dose ranges of 0.5–12 mg / week (0.5–12 mg weekly), administered weekly sc over cycles of research phase. Supplied in Thailand by Thailand Peptides, Bangkok-based, research use only.
Triple-agonist peptide showing dose-dependent weight reduction in Phase 2. Glucagon component drives additional energy expenditure.
Published and preclinical data are summarised below; dose ranges shown reflect protocols in the research literature and should be interpreted accordingly.
How does Retatrutide work?
Retatrutide is a single-molecule triple agonist at GLP-1, GIP, and glucagon receptors. Glucagon-receptor activity increases hepatic glucose output and energy expenditure, which, when balanced against the glycaemic and satiety effects of GIP/GLP-1 co-agonism, produces dose-dependent weight loss greater than that observed with dual or mono-agonists in published Phase 2 trials.
Receptor binding affinity and post-receptor signalling for Retatrutide remain areas of active investigation; several proposed effects within the GLP-1 Metabolic class are currently supported only by in-vitro or rodent data, and should be interpreted accordingly.
Retatrutide pharmacokinetics
- Half-life
- Approximately 6 days in Phase 2 data, supporting weekly administration.
- Bioavailability
- SC bioavailability consistent with other fatty-acid-modified peptide agonists in this class.
- Route of administration
- Subcutaneous injection once weekly in reported trials.
- Metabolic clearance
- Proteolytic; long-term safety and clearance pathways still under active investigation.
Retatrutide research timeline
- 2023 Jastreboff et al., Phase 2 obesity trial showing dose-dependent weight reduction up to ~24% (N Engl J Med).

Stacking Retatrutide
Commonly referenced pairing with Retatrutide: Monotherapy. Stacking rationale should be grounded in complementary mechanisms, not additive speculation; interactions at shared receptors or enzymatic pathways should be accounted for. Both compounds in a Retatrutide stack are supplied by Thailand Peptides on the same order via the Bangkok research desk.
Contraindications
Unestablished safety profile. Additional caution is warranted in individuals with hepatic or renal impairment, endocrine disorders, or concurrent pharmacotherapy affecting the pathways described above.
