Purity you can verify. Service you can rely on.
PEPTHOS exists to give researchers a source of peptides they can actually trust. Every compound we ship is third-party tested by independent laboratories for both identity and purity, and arrives with a Certificate of Analysis so you can verify exactly what's in the vial.
We focus on three things: verified quality, transparent documentation, and fast, careful fulfillment. Orders placed before 2pm ship the same business day as lyophilized powder in tamper-evident vials, each carrying a lot number that matches its Certificate of Analysis.
HPLC purity & identity on every batch.
COA & batch records with every order.
Same-day shipping on early orders.
