AST’s most recent release was Urso-X an ursolic acid formula. It fitted in with their style of individual ingredient products. However their next one is going to be their most mainstream supplement to date. AR-5 is an amino acid concentrate. A flavored powder with about 30 servings per tub. Based on the size of the bottle it will probably have nothing outside of the amino acid family. AST have not set a date but if Urso-X is one to go by it should be here within the month.
