A while ago I bought a couple of bottles of BCAAs and have been taking 2 just before I begin my first set, 1 in the middle of my workout and two just after finishing my last set.
I basically lost a bottle this winter and recently found it. It was in my car. Its been in the freezing cold minus 15 to minus 30 degrees Celsius. I’m worried the bottle may be ruined.
Is it?
