How Long Does Reconstituted Semax Remain Stable for Research Use?

Semax ships as a freeze-dried powder, and that lyophilized state is what allows it to remain chemically stable in frozen storage over an extended period — moisture removal during freeze-drying is what protects the peptide from the degradation pathways that become active once it's dissolved.

After reconstitution, refrigeration slows this degradation but doesn't stop it, which is why reconstituted Semax has a shorter practical usable window than the dry powder form. This is standard across essentially all of REVIVE LAB UAE's lyophilized peptide catalog, not unique to Semax specifically.

A reconstituted solution showing cloudiness, discoloration, or visible particulate should be treated as unusable regardless of elapsed time — basic visual inspection before use is standard laboratory practice.
