Tried to PM you but couldn't. I've used one called Body Strong BCAA powder (Unflavored 1320 grams). It is instantized. I have gone through 2 of these 1320 grams containers. Not too bad for a bulk flavorless BCAA powder. Only other cheaper BCAA powder is from TrueProtein if you buy 1 kilo or more of either the instantized or the regular BCAA powder. If you want pre packaged 1 kilo size, then I beleive Omega Sport BCAA 1000g powder is the next best option. Good luck!
