I guess it depends on what you're after. Glutamine, BA and Citrulline certainly aren't cheap fillers, and each have their own unique effect. If you're just after plain BCAAs, get just that and it will be the cheapest option. If you want an intra workout with effects you'll feel, get a product with the above ingredients.
Sorry but they are cheap fillers, BCAA's are the only expensive thing in there.
You buy BCAA's
L Glutamine retails (ie selles to customers) for $29 per kilo
Beta alanine retails for $49 per kilo
Citruline Malate sells for $69 per kilo
All well below $99 per kilo, so they are in this case cheap fillers.
