Quick answer: Feed-grade lysine comes mainly as L-lysine HCl (98.5% purity, about 78.8% lysine) or L-lysine sulphate (about 50–55% lysine plus other nutrients). Compare products on price per kilogram of actual lysine, not per bag. Check the certificate of analysis, moisture and particle flow, and store bags sealed and dry.
