- Great Product
matty, norfolk 17/03/2016
love the chocolate best taste ever, great results def worth buying.
- Does What It Says
Vince, UK 22/05/2017
Use this properly and you will see muscle gains.
The greater your body mass, the more extra calories you will need to make gains. I needed half the recommended amount.
Calculating the correct calorie intake is crucial. As is calculating the correct amount of exercise. A common misconception is the more you work out, the more you gain. False. Over training leads to failure. I only train 20 mins three times a week, and I gained 3/4 of a kilo per week.
No one can gain more than this in a week, unless it's fat.
- Great Tasting Non Bloating
Steve, Bournemouth  09/12/2016
Excellent product to get the calories on board when you can't eat, I take after training. It tastes great especially the chocolate peanut flavour. I would certainly recommend this product.

Directions

Read product label before use.
Add two heaped scoops (334g) of Serious Mass to a blender filled with 710ml (24oz) of water. Blend for 45-60 seconds. Then add a few ice cubes and, if desired, other calorie contributing ingredients and blend for an additional 30-45 seconds.

Serious Mass can be used to feed serious calorie needs in a variety of different ways:
Between Meals: Drink half to one serving of Serious Mass between meals to support a high calorie diet.
Post Workout: Drink half to one serving of Serious Mass 30-45 minutes following exercise.
Before Bed: Drink half to one serving of Serious Mass about 45-60 minutes before bed to provide nutrients to muscles throughout the night.

Tip: New users may find it beneficial to begin with half a serving for the first week and then gradually increase to one or more full servings several times a day.

Warning: Not for use by those with pre existing medical conditions or those taking any medications, those under the age of 18 or women that are pregnant or breast feeding.
Caution: Keep out of reach of children. Do not exceed recommended daily intake.
