Mass & Size Product Range


Made up of amino acids, protein is an essential nutrient important for many functions within the body, such as muscle development. For individuals who are training hard to either maintain size or gain mass through muscle growth, protein requirements should increase from 0.8g protein per kilogram body weight per day (g/kgBW/day) to 1.5 - 2g/kgBW/day.

Maximuscle PROGAIN powders contains BioMax True Protein, a unique blend of protein, which is rapidly digested by the body and allows for the fast uptake of protein, stimulating muscle development and growth.

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 powders 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 powders provides 30g of high quality BioMax True Protein to help support the growth and development of muscle.


Vary your protein sources throughout the day.

Split your total protein requirement into 20-40g servings every 3 hours.

Consume protein in close proximity following exercise.

Casein protein, found in dairy products like milk, is a slow release protein which makes it ideal to consume before bed.

Maximuscle products will help supplement your diet, aid convenience and provide the support you require.


If you want to increase muscle size, resistance training is required, as without the exercise stimulus your muscles will struggle to get bigger. This exercise increase will require a suitable energy increase. To make the gains you want ensure that your exercise is appropriately fuelled before, during and after exercise.

Creatine is a non-essential dietary compound that is found naturally in foods like meat and fish. It is also produced in small quantities (˜1g) within the body (in the liver) and stored in muscle cells, where it’s used to power bursts of high intensity muscle contractions. Creatine supplementation has been scientifically proven and remains one of the world’s most popular sports nutrition ingredients.

Creatine supplementation is proven to increase physical performance during successive bursts of short-term, high intensity exercise when a minimum of 3g of creatine is consumed daily.


Following the equation below will help you determine your energy requirements. Follow the step by step guide to calculate your calorie requirements.

First you need to calculate your Basal Metabolic Rate:

MEN BMR = 66 + (13.7 x WEIGHT (kg))+ (5 x HEIGHT (cm)) - (6.8 x AGE)

WOMEN BMR = 655 + (9.6 x WEIGHT (kg))+ (1.8 x HEIGHT (cm)) - (4.7 x AGE)

Multiply your BMR by 1.55, the activity factor for exercising 3-5 times per week.

Ensure a calorie excess to support your training by adding an additional 500 calories to your activity adjusted amount.

Divide the calorific value into the 5-6 meals you have each day.
