Why Progain?

Progain is an athlete level shake designed to help you gain weight as part of your diet and training routine. It’s trusted by thousands of professionals to help them safely reach their target weight and size. Progain is a blend of fast-acting whey proteins that support muscle size. We also add complex carbohydrates to increase the calorie load. Progain naturally includes 7g of BCAAs in each serving, which the body cannot make by itself. Progain supports effective muscle gains as part of a balanced routine of nutrition and hard training.

High in protein

Packed with 33g of protein, Progain contains a proprietary blend of high quality whey proteins, easily absorbed by the body to support muscle size.

Muscle building calories

Progain contains 460 calories in each serving, of which 140 calories are from muscle-building proteins. The balance of calories and proteins is formulated to satisfy hard-gainers who want to increase size and mass but struggle with taking on a higher calorific load in their day-to-day diet.

Naturally rich in BCAAs

Our formula includes 7g of BCAAs in every serving, with 3.4g of those coming from leucine. These amino acids are crucial parts of your diet because your body cannot make them itself.

Complex carbohydrates

With 55g of carbohydrates in each serving, Progain delivers the calorific load you need.

Supports skeletal strength

Progain is high in phosphorous, which is needed to help maintain normal bones. It is also a source of calcium which is essential for skeletal health.
