Retatrutide is a synthetic peptide studied as a triple agonist of the GLP-1, GIP and glucagon receptors. It belongs to the class of incretin-based research peptides.
It is investigated in metabolic and endocrine research programmes, where it serves as a reference compound for receptor signalling studies. PEPTIQUE supplies Retatrutide in 3 ml vials at four amounts to cover different experimental designs.

A technical comparison of the three incretin peptides studied in metabolic research — mechanism, target receptors, structure, published data, stability, and reconstitution. A laboratory guide.

Lyophilised powder vs. ready-to-use solution (pen): why form matters. How peptides degrade (hydrolysis, oxidation, deamidation, aggregation), why lyophilisation stabilises them and makes them resistant in transit, what 2–8°C means in practice after receipt, how to store them after reconstitution, and how to check a vial on arrival.
