What 2 to 8 degrees and protect from light each correspond to

Published 24 October 2026 · REVIVE LAB UAE Research Desk · 5 min read
The carton states storage at 2 to 8 degrees Celsius, protected from light. Refrigeration slows every chemical degradation pathway; protection from light prevents photo-oxidation of susceptible residues. Both conditions apply to the lyophilised product as supplied. A reconstituted solution is a different material and the carton statement does not describe it.

Refrigeration

Reaction rates fall with temperature. Refrigeration at 2 to 8 degrees reduces oxidation, deamidation and hydrolysis to rates at which a lyophilised peptide remains within specification for its labelled period. Freezing a lyophilised solid is not generally required and introduces condensation risk on removal.

The specification is the condition under which the material's stability was characterised.

Light

Tryptophan, tyrosine, histidine and methionine absorb ultraviolet and near-ultraviolet light and oxidise under it. The carton and the vial's packaging exclude the relevant wavelengths. Exposure is cumulative and the damage irreversible.

Protection from light is therefore about where the vial is kept, not only how cold.

Solid versus solution

The printed conditions describe the lyophilised product. Once reconstituted, the material contains water, degradation pathways that need water are active, and the stability of the solution is a separate question answered by measurement in that system. The carton does not speak to it, and neither does this page.

Retatrutide is supplied by REVIVE LAB UAE as an investigational research material for laboratory use only, with identity by mass spectrometry and purity by HPLC for the batch. It is not approved for any use anywhere, and no dosing, administration or protocol guidance is provided.
