That was the question that led us to create SUPLEX HEAVYWEIGHT® MASS GAINER FLAPJACKS - to make gaining muscle mass easier and tastier than ever before.
Oven-baked in Yorkshire, each bar contains 30g PLANT-BASED PROTEIN and 500+ CALORIES in one delicious OAT-PACKED flapjack. Messy mass gainers and processed protein bars? It's time to tap out.
