Triple receptor profile
Retatrutide is studied for its combined GLP-1, GIP and glucagon receptor engagement — a profile distinct from earlier dual or mono-agonist peptides.
Lab handling
Lyophilised storage at 2–8°C, reconstitution with bacteriostatic water and refrigerated in-use stability are standard. Always defer to your internal SOPs and the printed COA.
Why batch transparency matters
Triple agonists are sequence-sensitive — small impurities can shift assay readouts. Regena publishes HPLC purity for every batch on the lab reports page.
Frequently asked questions
Why are there so many strengths?+
Different research protocols need different total mg per kit. Right-sizing avoids waste and limits exposure to reconstituted material past its stability window.
Is retatrutide in stock?+
Stock rotates by batch — check the Peptide Library page for live availability.
