How Can I Tell If a Reconstituted Peptide Solution Has Degraded?

Most of REVIVE LAB UAE's reconstituted peptides should appear as a clear, colorless solution — GHK-Cu is the notable exception, where the expected appearance is a light blue tint from its copper complex. A solution that develops cloudiness, unexpected color change, or visible floating particles has likely undergone some form of degradation or contamination and should not be used.

Time is the other major factor: even a solution that still looks visually normal can be chemically degraded once it exceeds its typical usable window (commonly around 28 days for most of the catalog, refrigerated and protected from light). Visual inspection and elapsed time should both be checked, since a solution can look fine and still be past its practical stability window.

This describes basic visual quality-control practice for laboratory handling — it is not a certification of safety or efficacy, and REVIVE LAB UAE does not provide administration guidance for any product.
