Strongest CoA practice in this batch: dedicated CoA page links each peptide directly to Janoshik's own verification URLs, no login/request needed. But no UK company registration number disclosed anywhere on site.

No UK trading entity found
We searched UK Companies House thoroughly (exact name, exact phrase, and plausible variants) and found no matching registration, despite this site presenting as UK-based. This caps the CoA tier below green regardless of score. It is not proof of wrongdoing, only that we could not confirm who operates this business: see methodology.

Responsible Practice assessment
Material concerns- · Runs editorial pages quoting real clinical-trial weight-loss percentages for retatrutide, semaglutide and tirzepatide, which affiliate-refer readers to a third-party site to purchase, with a referral discount code. This sits alongside one of the strongest Certificate of Analysis setups in the index for the compounds it does sell directly, which is exactly why the two are assessed separately.
We assess what a brand publishes and makes available to customers, not its intentions. Full framework and what each status means: how we assess brands. Think this is wrong? Email [email protected] with evidence.
