How we scored it
Synthetic 12-amino-acid peptide (Ala/Asn/Gly/His/Ile/Lys/Phe/Ser/Trp/Tyr); amino-acid building blocks plus coupling leaves no mass.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.
Where it comes from
Solid-phase synthesised from natural amino acids. No alternative route noted.
