How we compare prices

We compare the core dosage of each compound — the vial strength with the deepest market data — listing RS Bio Labs against a range of UK stockists, sorted cheapest-first, with cost-per-mg (price ÷ mg). Competitor prices are drawn from publicly listed prices and the PeptideSupermarket aggregator, and this snapshot is automatically refreshed every 24 hours.

It's a snapshot of selected stockists, not an exhaustive survey of every UK vendor, and prices can change between updates. All products are supplied strictly as laboratory research materials for in-vitro scientific use only.
