L-tryptophan (feed grade)
L‑tryptophan (feed grade) is an essential amino acid supplied as a fine powder with the chemical formula C11H12N2O2, used primarily in poultry, swine and aquaculture feed formulations.

Shelf life is generally around 24 months when kept in dry conditions, which aligns with industry expectations. The product complies with ISO and SGS certification requirements as stated by the supplier.
