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 — they're 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 —

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 —

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 —

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 —

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.
