The Pepthea standard
Radical transparency is the whole brand.
Purity on the label, not in the marketing.
Every compound ships with its measured purity and identity. We print the number and back it with the data — no "high quality" hand-waving.
Every lot, lab-verified.
Identity by mass spec and purity by HPLC on every production lot, with the certificate of analysis published under its lot number.
