Research Reference

The metabolic peptide ladder — Semaglutide → Tirzepatide → Retatrutide

Understanding receptor coverage helps researchers select the right compound for their protocol stage.

①

Semaglutide — GLP-1

Single-receptor agonist. The standard entry point for new metabolic research protocols. Effects one receptor pathway in metabolic studies.

From £95 · View kit →

②

Tirzepatide — GLP-1 + GIP

Dual-receptor agonist. The intermediate step when single-pathway tolerance has been observed. Provides broader mechanistic coverage.

From £106 · View kit →

③

Retatrutide — GLP-1 + GIP + Glucagon

Triple-receptor agonist. The most advanced compound in the class — ideal when dual-agonist protocols have plateaued. Broadest receptor profile.
