Muscle building Gainer
Brilliant weight gainer for muscle building. Has a great protein profile. The quality of the product is very high and well packed. Although it has huge serving portions you can always adjust to what you need to meet your requirements. It dissolves well and tastes really good compared to a lot of others I’ve tried. It has a smooth texture after just a few shakes in a bottle and goes down nicely.

Tastes great no crappy aftertaste
Just bought this Strawberry and Cream First of all it smells amazing . I'm getting old (55) and I'm an extremely busy person ... i don't go to the gym never have never will and bought this as additional calorie intake. 1st impressions .... you will need a massive shaker to fit in a full serving . I ended up doing 1/2 serving with 500ml of water twice. It mixes absolutely fine with no clumping ( I did only add a little at a time to the water ) Tastes absolutely fine with no crappy after taste . No complaints

AQUIRED TASTE
does the job but not the best of tastes.

Disappointed with quality and taste.
The taste was unpleasant, and the texture made it hard to drink. I didn’t notice any benefits after using it for a week. Wouldn’t recommend it to others looking for results.

Just as good as Optimum Nutrition
3 weeks ago I weighed 68.8kg. I now weigh 72.1kg. I have been eating about 3250 calories a day, and I have been using 2 scoops of this powder and a pint of milk ever morning. That equals just over 1100 calories which really helps me get my calorie count off to a good start each day. I mix it in a blender which makes it smooth. Not sure how others get on with it using a shaker. It tastes nice, and I haven't got bored of it yet.

Best Mass Gainer
Regularly get this on my bulk. Has a mix of different protein types. Casein for a slow release. Whey for quick release. All the vitamins and creatine. Genuinely is an all in one. Always tastes great with milk. Mixes easily and fast digesting. Can be able to consume over 1000 calories from this and then have a meal couple hours later. Definitely will carry on using whilst on the bulk. Making it easier.

Hmmmmm
Confused how the 2kg has 18 servings, yet the 5.4kg has the same 18 servings?
