    I’ve tried a few different BCAA products and JYM is definitely one of the best. The 2:1:1 ratio works really well for me – I recover faster and can train harder. A little pricey but you get what you pay for with the quality ingredients and transparency. Mixes easily too. Overall, very happy with JYM BCAAs as part of my supplement stack.
