so here's my direct side-by-side blue raz comparison (both mixed in 7oz of water):
-the new version mixes clear, as opposed to the now notorious (rip verba) yellowish-tint of the og version
-the new version has a more subtle taste. i would say it tastes less "chemically" than its predecessor. that being said, i personally prefer the stronger taste of the original version. however, oddly enough, i did find the new flavor more "refreshing". basically, i'd opt for the og version if i were looking to chug some aminos, but would go for the new version if I were looking to sip on something over an extended period of time (ie intra-workout). so all in all, i think pes did upgrade on the flavor system considering the product's intended use.
thanks again to the good bros at pes for hooking up the insider orders!
