Why researchers choose Peppi Nerds
Sourced, then tested again
Every lot is sent to an independent lab before it is listed. The result is published as a dated COA you can open from the product page, not a purity number typed into a description.
Packed for the bench, not the mailbox
Vials ship in a plain outer box with protective inserts. Storage guidance is printed on the packing slip and repeated in the storage guide.
Premium documentation, without the premium price tag
The same COA, the same plain protective shipping, the same entity-named catalog you would expect from the biggest vendors, priced for researchers who order often.
Every lot, tested and documented
A certificate of analysis (COA) is the report an independent lab issues for one specific production lot. Ours are published per lot and linked from every product page, so you can match the lot number on your vial to its result.
| Lot number | Matches the number printed on the vial label |
|---|---|
| Entity | Official peptide name and, where public, sequence |
| Test date and lab | Date issued and the independent lab that ran it |
| Method | HPLC purity, mass spectrometry identity confirmation |
| Result | Purity percentage and net peptide content, as reported |
| Document | Downloadable PDF of the original report |
