I used beta alanine 3 or 4 years ago. Was bloody horrible, could only manage it for about 3 weeks. Still have half a 500g tub if anyone wants it. There's no best before date anywhere.
I love the stuff. Sprinkle it on my cornflakes. I'll take it, I can swap you for some other random bag of white powder with little to no scientific backing of efficacy behind its use. You sure you're not talking about BCAAs - coz they're feckin' disgusting.
