Lab tests

Third-party peptide lab tests

Purity claims mean nothing without a report you can open yourself. Every entry here links to a verifiable third-party analysis. Enter the report ID on the lab's own portal and confirm it hasn't been altered. We never invent numbers or verdicts.

How to read this index. A screenshot of a COA proves nothing, because they are trivially forged. What matters is the report ID matching your vial batch, confirmed on the lab's verification page. Entries labeled “aggregated from public discussion” summarize category-level patterns and point you at the portal. They are not verdicts we assert on our own authority.

BPC-157

Janoshik Analytical

Pass

Tested n/a

Community-submitted Janoshik reports for research BPC-157 batches routinely verify in the high-90s HPLC range with confirmed mass-spec identity. Open the source portal and enter the report ID printed on any COA to confirm it was not altered.

TB-500 (TB-4 fragment)

Janoshik Analytical

Pass

Tested n/a

Thymosin beta-4 fragment ("TB-500") reports aggregated from public discussion generally pass mass-spec identity; purity varies more by batch than BPC-157. Always match the report ID to the vial batch — a COA for a different lot proves nothing about yours.

Semaglutide

Janoshik Analytical

Inconclusive

Tested n/a

GLP-1 analog batches show the widest spread in publicly posted third-party tests, including under-filled vials and identity mismatches. Treat any purity claim without a batch-matched, verifiable report ID as unverified.

Retatrutide

Janoshik Analytical

Inconclusive

Tested n/a

Newer triple-agonist sequences have limited public test history. Where reports exist, confirm the report ID on the lab portal rather than trusting a screenshot — screenshots are trivially forged.

Looking up a specific batch?

We index the certificates that reach us by batch number. Enter the number from a vial label or a certificate to see whether it is in the archive, along with HPLC chromatogram, mass-spec identity, endotoxin, and residual-solvent screening where the document reports them.
