I just got 300g of BCAA made by Dymatize nutrition in powder form. I assume the best time to take it on training days is pre-work out to inhibit protei breakdown during exercice. A spoon(5.2g) contains 1,262mgs L-Valine and L-Isoleucine respectively, and 2,526mg of L-Leucine. Is one scoop pre-WO sufficient, and should I take any on non-training days? My goal is to gain muscle mass if it helps.
