If such a thing as a hardcore muscle building protein bar for the gym rat exists, AST’s Musclebar is it. It’s definitely a protein bar – but it’s not just a protein bar, as you’ll soon discover when we look under the wrapper.

AST Musclebar weighs in at 62g and 240 calories. It has 22g of protein (a blend of Hydrolyzed Whey Protein Concentrate, Ion Exchange Whey Protein Isolate, Complete Milk Protein, Calcium Caseinate and 4000 milligrams of Branched Chain Amino Acids (L-leucine, L-Isoleucine, and L-Valine) – not to mention L-Glutamine.

It also contains 7g of fat; 4g coming from saturated fats – no trans fats here.

Probably not a bar for those on low carb diets, the AST Musclebar contains 26g of carbohydrates (no sugar). However, this makes for an ideal pre or post workout bar so the carbs are put to good use in building muscle and not stored as fat.

And that’s not all…

The AST Musclebar is one of the only – and probably the first – protein bars to contain creatine – a substantial 5g of micronized creatine, to be precise.

So, if you are looking for a protein bar that packs more a punch than most, try the AST Musclebar.

It comes in boxes of 12, currently available in Chocolate Brownie Xtreme flavor.
