Reflex Instant Mass® Heavyweight

Instant Mass® Heavyweight is built for serious mass and strength goals. Big on protein, big on carbs and big on calories, it’s a convenient way to push daily intake higher when you’re training hard and struggling to meet targets through food alone.

Why choose Heavyweight?

Each serving delivers substantial protein and carbohydrate alongside over 1,000 calories, helping you stay in a surplus and recover from intense sessions. It also includes friendly bacteria and digestive enzymes, and uses whey protein from grass-fed cows for quality you can count on.

Who is it for?

Hard gainers, busy athletes, and anyone who needs a reliable weight-gain shake between meals or after training. If you’ve got a fast metabolism or a demanding schedule, Heavyweight helps you bridge the gap.
