Retatrutide
Triple agonist · GLP-1 · GIP · Glucagon
Retatrutide is a synthetic peptide that acts as an agonist at the GLP-1, GIP and glucagon receptors. It is supplied as a lyophilized reagent for in-vitro study of metabolic receptor signaling. It is not a drug, is not for human or animal use, and is not equivalent to any approved medication. Published literature is referenced for research context only.

Handling & storage
General laboratory handling guidance for lyophilized peptide vials. This is reference information for qualified researchers, not medical, dosing, or usage instructions.
Before reconstitution
Lyophilized vials arrive as a fine white powder or cake. Store sealed at 2–8 °C for short-term reference, or at −20 °C for extended stability. Keep away from light and moisture until you are ready to reconstitute.
Reconstituted form
Once reconstituted with bacteriostatic or sterile water, peptides are typically stored at 2–8 °C and used within the working window described in the associated research literature for that molecule. Avoid repeated warm-up / cool-down cycles.
Contents & excipients
Each vial contains the labeled research peptide only, with mannitol or a comparable lyophilization excipient where required for cake formation. No preservatives, no flavorings, no undeclared active ingredients. Full details ship with each lot COA.
Research literacy
What are these compounds?
What is a peptide?
Peptides are short chains of amino acids, the same building blocks that make proteins. They are used in laboratory research to study cell signaling, metabolism, tissue repair, and hormone pathways. They are not foods, supplements, or medicines.
What is retatrutide?
Retatrutide is a research peptide that activates GLP-1, GIP, and glucagon receptors. It has been studied in clinical trials for metabolic effects, but the material sold here is a research reagent only, not a drug, not for human use, and not equivalent to any approved medication.
Safety & compliance
Products sold by Sacred Peptides are supplied strictly for in-vitro laboratory research. They are not intended for human consumption, food, cosmetic, diagnostic or therapeutic use. Product information is for research literacy and must not be used to self-diagnose or self-treat. By purchasing you certify you are a qualified researcher and accept full responsibility for compliant use.
