Lab-verified quality
25 / 35| Item | Points | What we found |
|---|---|---|
| Published retatrutide lab report | 10 / 10 | Four Janoshik Analytical retatrutide reports are published on the seller's Retatrutide Tests page (tasks 81943, 68250, 68251, 57162). Source: leolabs.co.zajanoshik.com |
| Report can be verified with the lab | 8 / 8 | Each report links to a janoshik.com verify page with a key. Janoshik's Cloudflare challenge blocked us, so figures are not independently confirmed; under our scoring notes this does not reduce the score. |
| Report tied to current stock | 3 / 6 | Retatrutide is listed again (10-60 mg). The product page links the latest test (#81943, batch R829004), but the listing shows no batch number, so the link to current stock is unclear. Source: leolabs.co.zaleolabs.co.za |
| Report is recent | 2 / 4 | Newest retatrutide test: 07 Oct 2025 (task 81943), about 11.5 months before the snapshot, i.e. 6-12 months. Source: janoshik.com |
| Purity and measured content | 2 / 4 | Newest report #81943: purity 99.309% (meets >=99%); measured 11.61 mg vs 10 mg label = +16.1%, outside +/-10% (overfill). Source: janoshik.com |
| Independent buyer-submitted test | 0 / 3 | No Leolab/Leolabs/leolab.io vendor in Finnrick's public index; /vendors/leolab, /vendors/leolab-io, /vendors/leolabs return 404. No independent test found. Source: finnrick.com |
| Signs of fabricated test dataDeduction, up to -3 | 0 | No listed sign documented. #68251 is labelled '20 mg' but shares batch G60319 with the 30 mg test #68250; this is a labelling inconsistency, not one of the defined signs. Source: janoshik.com |
