When you need real calories to grow, you need more than just protein. Rule 1 Mass Gainer delivers 1260 calories, 40g of complete protein, 254g of performance carbohydrates, and added creatine to support strength and size. This is fuel for lifters who train heavy and recover hard.

Formulated with fast and slow-digesting carbs, high-quality whey proteins, and micronutrient support, this gainer helps rebuild muscle tissue and replenish glycogen so you’re ready to attack your next session. The macros are designed for athletes who burn high and need to feed that output. Smooth texture, rich flavor, and reliable digestibility make it easy to get more calories in without feeling bogged down. If your growth has stalled, this is how you push the needle forward.
