Alternatives to Precisionresearchuk in the UK: sellers you can actually verify
Precisionresearchuk (precisionresearchuk.co.uk) does not publish a certificate of analysis you can verify in its own name. If that is why you are looking for an alternative, the UK sellers further down do, so you can check the testing yourself before you buy. The Peptide Watch takes no vendor money and links to no seller's shop.
Why Precisionresearchuk is on the watch list
Precisionresearchuk tells buyers 'Batch-specific Certificates of Analysis (COA)'. The certificate is only offered on request, after the sale, and no laboratory is named, so there is nothing to inspect before buying. A certificate you can only see after paying cannot inform the decision to buy.
- Why it is on the watch list: 'COA on request', nothing published
- Trustpilot: 4.6 from 22 reviews, which reflects delivery and service, not what is in the vial
- Pricing: BPC-157 at £2.69/mg, 10% below the market median across the sellers we track. Untested product being cheap is not a bargain, it is the discount for taking the purity risk yourself
