I started taking 2 scoops of EXTND BCAA right after I lift. Is it worth it taking it on non lifting days? If so, how much and does it matter when? Should I be taking more than 2 scoops on lifting day? The package says to take double that (2 after lifting, and another serving of 2 some other time in the day) but often they say to take a lot more than you need to drive up sales.
