Product · MyDosage Checker

Check before you buy.

Paste a shop link, a brand name or a certificate. We report what is verifiable, what needs more proof, and what we simply cannot see. No account, no score for sale, and brands cannot pay or apply to be marked as checked.

The four layers we check

Who is behind it

Registration, company footprint, addresses, how long the operation has existed and whether the same people appear elsewhere.

How the shop reads

Claims, disclaimers, dosing language, pricing patterns and whether research-use framing is honest or decorative.

The documents

What a certificate actually reports: identity first, then amount, then who ran the test — and whether it matches the product.

Handling and shipping

Cold chain, packaging, stated destinations and what happens when something arrives wrong.

Where we cannot see, we say so — an unknown is never reported as a pass.

Already checked: the RUO brand list

We keep a public directory of research-use-only suppliers. Brands we have checked carry a checked mark and a rating; the rest are labelled “not yet checked”. Brands cannot request, buy or negotiate that status — we check, or we don't.
