COA matched the vial exactly
Cross-checked the batch number against the certificate of analysis on their site — purity numbers lined up with my own assay. This is the only vendor I've found that actually publishes per-batch testing.
Fast, discreet, well packaged
Ordered before the 3PM cutoff and it shipped the same day. Vials were cold-packed and the lyophilized powder was intact. Reconstituted cleanly with no cloudiness.
Consistent batch to batch
Third order across six months. Purity has been consistent every time and the support team answered a labeling question within an hour over chat.
Great product, would love more sizes
Quality is excellent and the copper peptide was a deep blue as expected. Only wish they carried a larger vial option for higher-volume work.
The blend saves me time
Co-lyophilized blend means one reconstitution instead of two. Documentation included both component COAs. Exactly what research workflow needs.
Customer support is real people
Had a delivery question and got a US-based rep on the phone immediately. Refreshing compared to other suppliers that ghost you after checkout.
