Pure iBCAA 4:1:1 is leucine heavy for those who want to experiment with higher leucine ratios in their intra-workout. Key Benefits: Leucine Heavy 4:1:1 Ratio 100% Instantised BCAAs for Easy Mixing and Better Absorption What are iBCAA's, and how are they different to my normal BCAAs? iBCAAs are Instantised Branch Chain Amino Acids, which means that our BCAAs have gone though an extremely advanced manufacturing process that makes them better mixing, and fully soluable in water. Our BCAA's don't create a mound of foam at the top of your shaker, or lots of white stuff that doesn't mix. Our iBCAAs are fully soluable in water, making for a better tasting, easier drinking, and more effectively absorbed BCAA formula. iBCAA's from Bodybuilding Warehouse can be taken on their own in water, or mixed into any other drink like fruit squash, a pre-workout, post-workout, or carbohyrate drink. An interesting post-workout shake could be for example: Example Post-Workout Recovery Recipe: 12g BBW Pure PeptoPro (Red Berry Flavour) 5g BBW Pure iBCAA 4:1:1 20g BBW Pure Waxy Maize Starch Mixed in 400ml water This would supply super-fast acting protein and amino acids, backed up with super-fast acting carbohydrates. At Bodybuilding Warehouse we pride ourselves on quality. Our Pure iBCAA 4:1:1 has been produced in-house in our own custom built facility, using ingredients from approved, audited suppliers who meet our strict quality assurance standards, and work within our principles.
