Buying TB-500 for research mainly means being able to check purity and documentation before ordering a vial. In this guide we explain, research-only, what to look for, how to check a COA, and why traceability makes the difference.
Buying TB-500 for research comes down to three things: documented purity (≥99%), a public and verifiable COA from an independent lab, and a traceable lot number. For research use only, not a medicine.
What to look for in TB-500 for research
The three core points are purity, documentation and traceability — without all three, reproducible research is not possible. New to TB-500? First read the background in what is TB-500.
Purity: ≥99% as the research standard
A purity of ≥99%, confirmed by HPLC and mass spectrometry, is the standard benchmark for research-grade TB-500. Lower or undocumented purity makes results harder to reproduce and to interpret within a research setup.
Reading and checking a COA
A Certificate of Analysis (COA) confirms the purity of one specific batch, linked to the lot number on the label. The full four-step explanation is in how to read a COA. Want to know how TB-500 compares to BPC-157? Read combining BPC-157 and TB-500, or see the equivalent buying guide buy BPC-157.
Reconstitution after purchase
TB-500 is supplied as a lyophilised powder and needs to be reconstituted before lab use. Calculate the right ratio with the reconstitution calculator, or read the step-by-step guide in how to reconstitute peptides.

Frequently asked questions about buying TB-500
What should you look for when buying TB-500 for research?
Look for documented purity of ≥99%, a public, per-batch verifiable COA from an independent lab (HPLC + mass spectrometry), and traceability via a lot number. Avoid suppliers without a verifiable certificate.
What is good purity for TB-500?
≥99% purity, confirmed by HPLC and mass spectrometry from an independent laboratory, is the standard research benchmark. A COA without an independent lab name or without a traceable lot number is not reliable proof.
How do I check a COA for TB-500?
Compare the lot number on the label with the lot number on the certificate, check the date and laboratory, and look at the purity percentage via HPLC. The full explanation is in the guide on how to read a COA.
Is TB-500 from Peptide Lab pure?
Yes, TB-500 is lab-verified at ≥99% purity by HPLC and mass spectrometry from Janoshik Analytical, with a public certificate per batch. For research purposes only.
