I bought 5lbs Nitrotech muscletech Isolate Whey Protein for ?4500 , 3 months ago.Earlier I was using Ultimate Nutrition Concentrate whey protein which was also pretty good.
If someone wants to bulk up and add some muscle mass to your body then I would peraonally not recommend Nitrotech Whey because it helps in building lean body with less fat.
I bought STRWABERRY flavour and it taste" awful".It has almost 50 scoops which makes it pretty expensive.However, I instantly got results.The packaging is also good.If you are very serious about gym then I would highly recommend this product.But make sure you purchase only CHOCOLATE flavour.
Before buying it make sure you check whether it is GENUINE or NOT.For further details and ratings , visit Bodybuilding.com.
