Research is only as good as the material behind it.
Fort Peptides was founded by analytical chemists who were tired of ordering compounds that arrived with generic certificates and inconsistent purity. Every lot we release is synthesized by solid-phase synthesis, assayed independently and published with a certificate tied to the exact number printed on your vial.
Four testing layers, every lot
- 01
Synthesis & cleavage
Solid-phase peptide synthesis with in-process purity checks before cleavage from resin.
- 02
RP-HPLC purity
Reverse-phase chromatography quantifies purity against a certified reference standard; we release at ≥99%.
- 03
Mass spectrometry
Electrospray ionization confirms the molecular weight matches the intended sequence.
- 04
Endotoxin & sterility
LAL endotoxin assay and sterility verification are run on the filled, capped vial — not on bulk powder.
