Consistent COA results
Independent HPLC matched the certificate to within 0.2%. Packaging is exactly as described — sealed pouch, twin-vial case, labelled water.

Best presentation in UK supply
I order from several UK suppliers for lab work. Proteus is the only one that ships as a true kit. The QR-to-COA flow saves time.

Genuinely research-grade
Lyophilised cake is intact, vials are well-sealed, and the lot tracking system is transparent. Will reorder.

Pricing without compromise
Cleaner supply chain shows. Half the markup of other UK suppliers, identical purity report. Dispatch was 24h tracked as promised.

Lot traceability is the differentiator
Scanning the QR resolves to the actual lab record, not a marketing PDF. That's the level of accountability I expect for research material.

Reproducible across batches
Three orders, three lots, three matching purity windows. Consistency at this level is rare in the research peptide market.

Clean labelling
Code, dose, lot, purity, and the research-only notice are all on the vial. No ambiguity. Exactly how research material should be presented.

Tamper-evident and intact
Sealed pouch arrived undamaged with the seal still intact. Twin clamshell case held everything firm — no movement in transit.

Direct sourcing shows
You can tell the difference when a supplier has actually been to the lab. Quality control is night and day vs. anonymous online sellers.
