Why Progain Extreme?

Take your mass and size goals to the next level by using Progain Extreme. Training to further increase mass and size requires the right nutrition, including an increase in protein intake. Progain Extreme provides 40g of protein in every serving using fast acting and slow release proteins. Every serving of Progain Extreme provides 600 calories, 3g calcium HMB and 40g of high-quality protein for gains in muscle size. It also naturally contains 9.9g of BCAAs and 7.9g of glutamine per serving. If you are making an attempt to achieve your peak size, Progain Extreme contains the extra nutrition that will help get you there effectively.

High in protein

Using the latest in cutting edge protein science, Progain Extreme contains our triple release protein formula that provides an impressive 40g of protein per serving for gains in muscle size. Our formula contains fast acting and slow release proteins to elevate amino acid levels in the blood for longer. Protein is scientifically proven to support gains in muscle size.

Naturally rich in BCAAs and Glutamine

Our protein formula naturally contains 9.9g of Branched Chain Amino Acids (BCAAs) in every serving, which includes 4.5g of the key amino acid, leucine. These amino acids are a crucial part of your diet because your body can't make them itself. Every serving also naturally contains 7.9g of glutamine, the most abundant amino acid in muscle.

600 calories

Progain Extreme contains a massive 600 calories, with 160 calories from 40g of muscle-building proteins in every serving. We have also packed every serving with 76g of complex carbohydrates including oats. When you're training hard for mass and size, add Progain Extreme to your diet - the additional calories and 40g of protein will help to maximise gains in muscle mass and size.

3g Calcium HMB

Every serving provides an impressive 3g of calcium HMB, a metabolite of the essential branched chain amino acid leucine. HMB is a well-researched ingredient and recommended by industry-leading experts.

Source of Fibre

Every serving provides a source of fibre, a key component of healthy, balanced diet.

Screened and effective

Every batch of Progain Extreme is screened for banned substances and is registered with the Informed-Sport programme.
