Ultimate 100% Whey Protein + Mass Gainer

MuscleTech researchers have engineered a brand-new, 5-in-1, hardcore mass gainer designed for individuals looking to put on an extreme amount of mass.  MASS-TECH® EXTREME 2000 features 80 g of protein, over 400 g carbs and 2,000 mass-producing calories (when mixed with 20 oz. of skim milk), plus 8.2 g of l-leucine, 10 g of creatine, and 20 vitamins and minerals for huge size and strength gains. MASS-TECH® EXTREME 2000 has everything you need to bulk up, pack on muscle and smash through strength plateaus♦‡

1. 100% Whey High-Protein Shake

Mass-Tech Extreme 2000 delivers more protein per serving than most other mass gainers available on the market. With a whopping 80 g of premium protein (when mixed with 20 oz. of skim milk), your body will have all the building blocks it needs to build the size and muscle you're looking for.♦‡

2. Multi-Phase Carbohydrate Complex

Mass-Tech Extreme 2000 supplies over 400 g of carbohydrates (when mixed with 20 oz. of skim milk) through a multi-phase carb complex to spike your insulin levels and promote muscle glycogen replenishment. This will help creatine reach your muscles and put your body in an extreme anabolic state.♦‡

3. High-Density Clean-Caloric Drink 

The new, scientifically superior Mass-Tech Extreme 2000 formula delivers over 2,000 calories (when mixed with 20 oz. of skim milk) and delivers high-quality whey protein and easy-to-digest complex carbohydrates. In a university study, subjects who added 2,000 calories to high-protein diet and a weightlifting program gained 6.8 lbs of mass (vs. 1.3 lbs. in the control group). This formula is so powerful you only need one serving a day!♦‡

4. HPLC-Tested Creatine Monohydrate Drink

Unlike our competitors that contain little to no creatine, Mass-Tech Extreme 2000 contains a clinically validated 10 g doses of creatine to help you increase strength and regenerate ATP stores that are reduced during resistance training. In a human clinical study, subjects gained 6 lbs. in just 6 weeks while using the same creatine doses found in Mass-Tech Extreme 2000!♦

5. High-Potency Branched Chain Amino Acid Shake

Each serving of Mass-Tech Extreme 2000 (when mixed with 20 oz. of skim milk) delivers 17.8 g of BCAAs, including 8.2 g of musclebuilding L-leucine. L-leucine is a powerful nutrient signaler that enhances mTOR activation and causes amplified protein synthesis. In a clinical study, L-leucine was shown to help subjects increase their 5-rep max strength by over 40% in just 12 weeks. What's more, when mixed with 20 oz. of skim milk, you get 14.5 g of L-glutamine and precursor to support muscle recovery. You won't find this amount of aminos in any other mass gainer on the market!♦
