What is Tirzepatide?
Tirzepatide is a research peptide in the GLP-1 Metabolic class. Dual GIP/GLP-1 receptor agonist; superior weight-loss endpoints vs mono-agonism. It is studied at per-dose ranges of 2.5–15 mg / week (2.5–15 mg weekly), administered weekly sc over cycles of titration: 4 weeks per step. Supplied in Thailand by Thailand Peptides, Bangkok-based, research use only.
Single-molecule dual agonist of GIP and GLP-1 receptors. Demonstrates greater A1c and body-weight reductions than GLP-1 alone.
Published and preclinical data are summarised below; dose ranges shown reflect protocols in the research literature and should be interpreted accordingly.
How does Tirzepatide work?
Tirzepatide is a single-molecule dual agonist at the glucose-dependent insulinotropic polypeptide (GIP) receptor and the GLP-1 receptor. Co-activation of both incretin receptors amplifies insulin secretion vs. GLP-1 alone; GIP activity at adipocytes contributes to greater body-weight reductions than GLP-1 monotherapy. Clinical head-to-head data (SURPASS-2) show larger A1c and weight reductions than semaglutide in type 2 diabetes.
Receptor binding affinity and post-receptor signalling for Tirzepatide 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.
Tirzepatide pharmacokinetics
- Half-life
- Approximately 5 days, enabling once-weekly dosing.
- Bioavailability
- SC bioavailability ~80% across the clinical dose range in trials.
- Route of administration
- Subcutaneous injection via prefilled pen or research vial.
- Metabolic clearance
- Proteolytic degradation; no significant renal or hepatic accumulation reported in SURPASS data.
Tirzepatide research timeline
- 2021 Frías et al., SURPASS-2 shows superior glycaemic control vs. semaglutide in T2DM (N Engl J Med).
- 2022 Jastreboff et al., SURMOUNT-1 demonstrates up to ~21% weight loss in adults with obesity (N Engl J Med).

Handling notes reflect methods used in published research protocols, not medical dosing guidance.
Stacking Tirzepatide
Commonly referenced pairing with Tirzepatide: 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 Tirzepatide stack are supplied by Thailand Peptides on the same order via the Bangkok research desk.
Contraindications
MTC / MEN-2, pancreatitis. Additional caution is warranted in individuals with hepatic or renal impairment, endocrine disorders, or concurrent pharmacotherapy affecting the pathways described above.
