Review posted on 23 Nov 2011
If you struggle to gain weight, or can't eat enough calories this product is excellent. I am naturally skinny but put on 1/2 stone in the first two months, and have now put on 3/4 stone over six months. I'm not a big fan of the flavours, they take some getting used to, I would particularly avoid the vanilla. Even with this I would still give this 5 stars because it works better than any other product I have used.
Great Product
Review posted on 14 Nov 2011
I have tried a number of products over the years, including those from ProLab, MuscleTech and Maximuscle to name a few, and I find this product by far the best all round nutritional supplement to support my training. It has a very good balance of calories, carbs and protein to help fuel your training sessions and promote growth.
This is also the first product I actually look forward to taking as it tastes great (chocolate), and it mixes really well with water using a decent shaker. I tend to use 2 scoops per 500ml of ice cold water, as if you go by the manufactures recommendation it’s a bit too thick and you will need a spoon to eat it. I’m what is classed as a ‘hard gainer’, so I needed a single product that was high in calories, carbs and protein and this product has really helped me pack on some quality size. I have not put on any fat at all with this product, only good solid muscle. If you’re looking for a great all rounder to pack on some size then look no further.

Good Stuff
Review posted on 27 Jun 2011
Had this stuff twice now,it is good, but I had to use only 3 scups instead of the normal 4, this is because you cant fit it in the shaker,
But still thinking's up nicely and tastes good, both banana and choc are nice and mix really well, and as long as your are eating a good meal you will put on the weight, I used this as a breakfast meal if I am in a hurry in the morning. the only thing I don't like is the price, and that the product does not last long, with 3 to 4 scups it does go quick.
