What this means

Elite efficiency — 40%+ of calories from protein. Lean meat, whey isolate, low-fat dairy. 96% density puts this in the Platinum tier.

Complete dairy protein (milk/casein), high DIAAS, counts in full.

Note: At 2.28g leucine per single scoop, this product sits below the 2.5g threshold needed to maximally trigger muscle protein synthesis in one serving. Common workarounds: use 1.5 scoops, or combine with another protein source in the same meal (e.g., Greek yogurt, eggs). More on the leucine threshold.

Notes

Whey-isolate + micellar casein milk blend (~52% whey iso / ~48% casein) designed for baking and cooking; the unflavored mix is unsweetened. Leucine estimated from the dairy factor (~9.5%) for the casein-heavy blend; clears the ~2.5g MPS trigger at ~1.1 scoops.
