Raw peptide materials
Peptide raw powder for buyers who fill, formulate or repack.
If you do your own downstream handling, you can buy the peptide as powder instead of finished vials. Each lot is tested on our line and has its own COA with HPLC purity and MS identity.
Powder or vials
Which format fits your work?
Raw powder suits buyers who weigh, fill or formulate in their own facility. If you want a finished, labeled product, order lyophilized vials instead. Both come from the same line and carry the same lot records.
| Raw powder | Peptide powder by weight, for your own downstream handling |
|---|---|
| Lyophilized vials | Freeze-dried in glass vials, neutral label by default |
| Purity | Release specification NLT 98.0% by HPLC; the actual result is on each lot's COA |
| Identity | MS molecular weight, on the same COA |
