- Weak0 – 4.9
- 1No certificates of analysis or third-party laboratory test reports are published on the site.

Third-party test reports: are they recent, lot-linked, and do they use methods that can actually prove identity and amount?
- Published test reportsFlagged
We found no certificates anywhere we could read on the site — no files, and no scans on the pages we opened. For a research-use seller this is the single most important thing to publish.
- Reports tied to a lotNot visible
No documents to trace back to a batch.
- What the reports sayFlagged
No third-party testing laboratories are identified, and no certificates of analysis are displayed. Homepage states 'Batch document: Ask our team'.
- Analytical methodNot visible
No analytical testing methods such as HPLC or MS are documented.
- 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.
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.
Trustpilot did not answer, so we treat their reputation there as not visible.

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