How Should Retatrutide Be Stored and Reconstituted for Research?

Retatrutide ships as a white lyophilized powder. In this freeze-dried state, sealed and kept at −20°C away from light, it remains chemically stable for extended laboratory storage. Light exposure is a specific concern for this compound, which is why desiccated, light-protected storage is called out separately from the general cold-storage requirement shared with most research peptides.

For reconstitution, 3–5 mL of bacteriostatic water is added slowly down the interior wall of the vial rather than directly onto the powder, then the vial is swirled gently — not shaken or vortexed, which can shear and damage the peptide's structure. Bacteriostatic water's 0.9% benzyl alcohol content also helps the reconstituted solution resist microbial growth across repeated laboratory use.

Once reconstituted, the solution should be refrigerated at 2–8°C, protected from light, and is generally used within 28 days for research stability. This describes standard laboratory handling only — REVIVE LAB UAE does not provide dosing, administration, or protocol-timing guidance for any product.
