Rule 1 R1 Clean Gainer is built for those chasing size without sacrificing clean nutrition. With 560 calories per serving, this formula blends 30 grams of fast- and slow-absorbing proteins to maximize muscle protein synthesis throughout the day.

The carbohydrate matrix is built on 97 grams of oats, organic rice bran, and pea starch—providing long-lasting energy and glycogen replenishment, not insulin spikes. There are no added sugars, creamers, or filler junk—just pure performance fuel.
