Being owned by Glanbia, the quality of BSN's protein and aminos is probably fine, however, the ratios are suspect because virtually all their products are prop blended.
For example, I'm fairly certain syntha 6's protein blend is 90% whey concentrate. The cholesterol content is the dead giveaway. It's almost identical to most WPC products. Additionally, it mixes up thinner than most true blends.
Amino X is a whole different story. The Canadian label shows the actual amount of BCAA's is paltry, with cheap filler like Taurine being the main ingredient.
I'm not a big fan of BSN aside from their flavoring. Go with virtually any other brand listed in this thread if you want a well designed product.
