How Should TB-500 Be Stored and Reconstituted for Research?

Published 2026-07-11 · REVIVE Peptides Research Desk · 2 min read
Short answer: Lyophilized TB-500 should be kept at −20°C in a sealed, desiccated container prior to use, and reconstituted with bacteriostatic water (roughly 2–3 mL) added slowly to the vial wall rather than directly onto the powder, to protect the peptide's structure during dissolution.

TB-500 is supplied by REVIVE LAB UAE as a white lyophilized powder, the same freeze-dried format used across its research peptide catalog. Freeze-drying removes moisture, which is what allows the peptide to remain chemically stable in frozen storage over an extended period, provided the vial stays sealed and desiccated.

For laboratory handling, bacteriostatic water is the standard diluent, typically in the 2–3 mL range per vial. Adding it gently down the interior wall of the vial, rather than injecting it directly onto the lyophilized cake, reduces mechanical disruption of the peptide during reconstitution. Bacteriostatic water's 0.9% benzyl alcohol content also helps the reconstituted solution resist microbial contamination across repeated laboratory handling.

After reconstitution, the solution should be refrigerated and is considerably less stable than the dry powder form.
