GNC AMP Sustained Protein Blend – Cinnamon Toast (28 Servings) | 7-Hour Protein Release

Overview

GNC AMP Sustained Protein Blend in Cinnamon Toast is a multi-source protein powder designed to support protein availability across hours. Built from four protein sources—native whey isolate, micellar casein, egg whites, and whey hydrolysate—this formula targets a seven-hour window of protein release to align with active routines throughout the day.

What you may experience

The blend combines rapid-release protein for immediate post-workout fueling with seven hours of sustained protein to help keep amino acids available as you go about your day. It also includes essential BCAAs, which are commonly associated with muscle support and recovery in training contexts. While individual results vary, many users find themselves feeling more consistently fueled between meals and workouts.
