What Is the Purity and Molecular Weight of REVIVE LAB UAE's TB-500?

Published 2026-07-11 · REVIVE Peptides Research Desk · 2 min read
Short answer: REVIVE LAB UAE's TB-500 has a molecular weight of approximately 1880 Da, is supplied at 5 mg per vial, and is verified at ≥98.8% purity by HPLC, confirming the synthesized peptide matches the intended 17-amino-acid Thymosin Beta-4 fragment sequence.

The ≈1880 Da molecular weight is the expected mass for the 17-amino-acid TB-500 sequence; a batch that deviates from this figure would indicate an incomplete or contaminated synthesis, which is why molecular weight verification is a standard part of quality control for every lot.

HPLC purity of ≥98.8% means that under chromatographic analysis, at least 98.8% of the sample by peak area is the target TB-500 peptide, with the remainder made up of trace synthesis byproducts or related sequence fragments — within the tolerance research suppliers use to classify a batch as high purity. REVIVE LAB UAE issues a Certificate of Analysis (CoA) per lot, available on request, documenting these results.

Each vial ships as 5 mg of white lyophilized powder for −20°C desiccated storage. As with all specs published by REVIVE LAB UAE, this reflects laboratory documentation for a research reference material — not a dosing chart, and not a therapeutic claim.
