Rapidly add mass

Based On Research At A Leading American University – Test Subjects Rapidly Added Mass!

An 8-week study examined the addition of 2,000 calories (over 2,000 calories are found in 2 servings of MASS-TECH®® each mixed with 2 cups of skim milk) to a high-protein diet containing approximately 2,300 calories and a weightlifting program. On average, subjects gained 6.8 lbs. of mass, while control subjects gained 1.3 lbs.

Increased CHest & arms size

Test Subjects Increased Chest & Arm Size!

In the same study, test subjects gained massive size directly on their chest and arms. Subjects gained 1.2 inches on their chest and 0.5 inches on their arms vs. the control group, which only added 0.5 inches and 0.2 inches. Imagine how you’d look with extra size on your arms and chest!

80g protein


MASS-TECH® features 80g of protein when mixed with 2 cups of skim milk, which supplies fast-, medium-and slow-digesting proteins. The multi-phase protein system provides critical amino acids to the body at varying speeds for extended delivery of amino acids in the blood.

70g bcaas


The formula’s protein dose when mixed with 2 cups of skim milk supplies a massive 17g of BCAAs and 8g of leucine, which help fuel your skeletal muscles, preserve muscle glycogen stores, and reduce the amount of protein breakdown.

1,010 calories


This powerful formula delivers a massive, 1010 calories derived from high-quality protein and quickly digested carbohydrates. It is the most versatile weight gainer available and can be taken once daily or split into two separate half servings.

156g carbs


MASS-TECH® supplies 156g of carbohydrates when mixed with 2 cups of skim milk through a multi-phase carb complex to spike insulin, quickly shuttling creatine into the muscle, and promoting muscle glycogen replenishment. MASS-TECH® puts your body in an extreme musclebuilding state!

Ultra-Clean Formula With Best-In-Class Taste

MuscleTech® researchers work closely with some of the top protein-flavoring professionals in the world, and each flavor of MASS-TECH®® undergoes multiple rounds of internal taste tests to ensure we deliver the absolute best. The result is a great-tasting formula you’ll look forward to drinking again and again!

Tested for Quality and Purity

When you buy a protein formula, you’re probably assuming what they say is in the bottle is actually in the bottle. Unfortunately, that’s not always the case. MuscleTech is one of few companies who only partners with GMP compliant manufacturers (the platinum standard for manufacturing) and then personally audits them! This includes using an independent lab to test every product lot, to guarantee that what we say is in the bottle is actually in the bottle. We’re never surprised when it is, since we use a rare practice called “overages” to put a bit more protein in each scoop than we promise on the label.
