What to Check Before Buying TB-500 Online
Before buying TB-500 online, the single most important check is whether the supplier publishes a batch-specific COA with HPLC purity and mass-spec identity data, because a supplier that will not share test data cannot demonstrate what is in the vial. Every other check — price, shipping, site design — is secondary to the certificate.
Our supplier vetting checklist breaks the verification into a repeatable five-step process.
COA and Third-Party Testing
A legitimate COA lists the batch number, the test date, the molecular formula, HPLC purity (ideally ≥98%), and the analytical method used, and the strongest suppliers pair their in-house COA with independent third-party testing. A COA that is generic, undated, or missing the purity number is not verification.
For what separates a real COA from a marketing document, see our purity guide.
Research-Use-Only Compliance
A compliant online supplier labels every peptide as research-use-only and makes no human or therapeutic claims, and this is actually a positive signal rather than a limitation — it means the seller follows the regulatory framework for research chemicals. Suppliers that advertise clinical benefits on the product page are a red flag.
For how this shapes sourcing in Europe specifically, see our European wholesale guide.
What to Do When TB-500 Is Unavailable
If a verified supplier is out of TB-500, the practical move is to source a closely related peptide for the same tissue-repair research, such as BPC-157 or CJC-1295, rather than dropping to an unverified seller. Availability should never override verification.

Frequently Asked Questions
Q1: What is the most important check when buying TB-500 online?
A batch-specific COA with HPLC purity and mass-spec identity data — a supplier that won’t share test data cannot verify its product.
Q2: What should a legitimate COA include?
Batch number, test date, molecular formula, HPLC purity (≥98%), and the analytical method used.
Q3: Is a research-use-only label a red flag?
No — it is a positive signal that the supplier follows research-chemical compliance and avoids prohibited human-use claims.
