I've used this protein before and been through 4, 2kg tubs. I'm using this as I'm getting back into my weight training after loosing weight, until reaching my goal. As an all round protein it is brilliant, it has all the amino's added as well as creatine with a good amount of protein, plus it mixes well and tastes great. I blend mine with a tray of ice cubes and a bit of water to create a thick milkshake style shake just without the added calories of milk! I only have 1 per day before my workout but this is usually joined with a tin of tuna in the day at some point giving good protein intake. Would and do recommend this to anyone, better than maximucsle and other big brands.
