Why we publish this
RU58841 is not a licensed medicine anywhere, so nobody checks it for you. The only way to know what's in a bottle is an independent lab test you can verify. Ours is above. Anyone can check the key on Janoshik's own website, so you don't have to take our word for it.
If you're buying RU58841 in the UK from anyone, ask them for the same thing: a lab report with a task number and a key you can check on the lab's site. No report, no sale.
