The benefits of Maximuscle Progain

For individuals looking for muscle growth - protein is the key. Maximuscle Progain offers a convenient way to boost the protein content of your diet whilst providing complex carbohydrates in a low sugar shake. Progain is specifically designed to support individuals who want to build muscle size. Each 120 g serving contains 30 g protein, 67.8 g carbohydrate and is 480 kcal. Progain is high in fibre and naturally provides 8 g of BCCAs and 6 g of glutamine.

What makes Maximuscle Progain different?

Maximuscle Progain is newly formulated with 30 g of BioMax True Protein, a blend of whey protein and milk protein (casein) providing both fast and slow acting protein. Progain can be used following exercise or in between meals to provide additional dietary protein and carbohydrate.

Typically, food protein concentrations are theoretically calculated based on the total nitrogen content, but this can cause some variances in the derived protein level. Maximuscle have gone one step further by validating the protein concentration in Progain by comparing the weight of the individual amino acids with the calculated factored amount, qualifying this as BioMax True Protein. We guarantee that every serving of Progain provides 30g of high-quality BioMax True Protein to help support the growth and maintenance of muscle.

For Maximuscle Athletes and Ambassadors, Progain is the preferred choice - they can go into competition with peace of mind, knowing that all of Maximuscle products are screened for banned substances and accredited by the Informed-Sport programme.

Maximuscle only use proven, reliable ingredients with known scientific benefits in our products.

Chris Todd Superb
I use this during my growth phase as I prefer to avoid creatine, the product doesn't cause me any issues mentioned by the other reviewers although due to the amount which is pretty close to 1L when mixed, I do drink it over 15 minutes or so - if it was better concentrated this might help. I've found it helps my performance and growth exactly in the way I want, but only use it once on training days then rely on sustain.

Thanks again for the review.

Kind regards,


Same as Gary McKay - both the old and new formula but no problems with restore or cyclone. Progain works however I reduce the intake to 2 scoops to avoid the digestive issues Gary mentions (presumably due to the complex carbohydrates in it). I find 1.5 scoops of progain with 1 scoop of cyclone or 2scoops progain with half a scoop cyclone also avoids the stomach problems but maintains the protein content.
The MaxiNutrition Team:

Hi Gary,

Thanks for highlighting this.

We are glad to hear you have found a way to consume the products without getting digestive issues.

Have a great day,

Kind regards,


Gary McKay Not for me
For some reason the product did not agree with me. I had gas, the runs and it generally upset my routine. I have no problem with any other maxi products and delivery is always spot on.
The MaxiNutrition Team:

Hello Gary,

Sorry to hear about your experience with our product.

We are concerned about the Progain not agreeing with you and giving you gas and the runs. A member of our Consumer Relations Team will be in touch shortly to help you with this.

Apologies again for any inconvenience caused,

Kind regards,
