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

    1 of 1 document link we tried opened publicly.

  • 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 sayNot visible

    The site lists a COAs page link and mentions third-party lab testing, but specific independent lab names are not detailed in the extracted text.

  • Analytical methodNot visible

    The text mentions HPLC and Mass Spectrometry testing methods, but specific lab reports with methods are not directly visible in the provided text.

  • Named third-party labNot visible

    No outside laboratory is named. In-house numbers are not independent evidence.

  • Document recencyNot visible

    The documents carry no date we could read from the server.

    The link returns text/html; charset=UTF-8 rather than a document file. Nothing in the link or its label ties this report to a specific lot or batch.

Social proof evidence
Weak signal · 12% of the score

Third-party ratings and public threads, read directly at the moment of this check. They are easy to buy and easy to brigade, so they are weighted low and can never overturn a lab-evidence flag. Every source below is also logged in the evidence trail.

Inside the reputation pillar (12% of the model)

Reputation is deliberately the lightest pillar. Even a perfect rating cannot lift a report over a lab-evidence flag.
