Reviews
Cold-chain handling was noticeably more careful than the last two suppliers I tried. COA matched our internal HPLC trace within 0.1%. Only docking a star because I'd prefer a printed COA in the box rather than a link. Will reorder.
Quality is excellent and purity checks out. Would give 5 stars if the outer box was a bit more robust — contents were fine but the box had some denting in transit. Product itself was perfect.
The cold-chain packaging impressed me most — dry ice still present on arrival despite a 3-day transit. Product quality matches the documentation. Pepthera clearly invests in proper logistics.
Cold-pack still cold on arrival. Tamper-evident seal intact. The kind of attention to fulfillment detail that signals the rest of the operation runs the same way.
Documentation discipline matters in this field. Every Pepthera shipment has a COA bound to the specific batch by serial, not a generic spec sheet. That distinction is the difference between supplier and source.
I run a regulated lab. The QC presentation here — sealed vials, serial-tracked COAs, batch metadata — is closer to a regulated supplier than a research outlet. That standard is rare.
