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

    6 of 6 certificate links opened publicly, but we could not read their contents.

  • Reports tied to a lotClear

    At least one report is published against a specific lot or batch, which is what makes it mean anything for the vial in your hand.

  • What the reports sayFlagged

    No third-party testing laboratory is named, and no lab certificates were readable in the provided text.

  • Analytical methodNot visible

    The site claims assays use reversed-phase HPLC and mass spectrometry, but raw data and analytical methods are not visible in independent reports.

  • Named third-party labNot visible

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

  • Document recencyClear

    The freshest certificate is about 1 months old, by the date the file last changed.

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.

Confidence breakdown

The score is a weighted mean over the pillars we could actually read — 70% of the model on this run. Anything we could not see is left out of the maths rather than counted against the seller.

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.
