Do BCAAs really build muscle or is that just a bro myth?
BCAAs are always hyped up in the gym, but do they actually work? Let's break it down. A review from 2017 analyzed multiple studies on BCAAs and muscle growth, showing they might help with recovery but have minimal effect on muscle hypertrophy compared to whole protein sources. Another study in 2021 echoed that, finding no significant gains in muscle mass for those supplementing with BCAAs versus those getting adequate protein from food. Essentially, if you're smashing your protein intake from sources like chicken or whey, BCAAs are just extra cash down the drain. Better save that cash for a new pre-workout or some heavy weights!
