How the score is built

Third-party test reports: are they recent, lot-linked, and do they use methods that can actually prove identity and amount?

  • Published test reportsClear

    We opened and read 3 certificates out of 4 candidates found on the site, including certificates published as scans.

  • Reports tied to a lotFlagged

    The reports we saw are not tied to a lot or batch, so they cannot tell you about the specific vial you would receive.

  • What the reports sayClear

    GHK-Cu tested at 99.747% purity by Janoshik (2026-09-18). Melanotan 2 tested at 99.715% purity by JANOSHIK (2026-09-18). BPC-157 tested at 99.748% purity by JANOSHIK (2026-09-18).

  • Analytical methodNot visible

    The opened lab certificates do not state the analytical test methods used.

    The freshest certificate is about 1 months old, by the test date printed on the report.

Social proof evidence
