Verification
How we verify
01
Fill
Lyophilized cake in a 3 mL vial. Retain pulled from the same lot.
02
Third-party panel
HPLC purity, MS identity, net peptide, TFA, endotoxin, sterility.
03
Publish
The lot gets a permalink. A researcher holding the vial can look it up.
04
Ship
Inventory publishes behind the certificate — not the other way around.
Diluent
Bacteriostatic water
The usual laboratory diluent for reconstituting a lyophilized cake. Sold separately. Compounds do not include syringes or imply a route of administration.
