Simple Peptide overview based on available store text.

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 sayFlagged

    Mentions independent third-party testing and a searchable COA archive, but no independent laboratory names are specified in the provided text.

  • Analytical methodClear

    Mentions HPLC/MS analysis, purity, sterility, endotoxin, and net peptide testing for lot release.

  • 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.

Certificates we opened
  • COA archive

    Opened publicly, contents not readable. No lot or batch reference.

    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.

Confidence breakdown

The score is a weighted mean over the pillars we could actually read — 88% 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.
