Anyone else use Vitamin C before they train? Vitamin C has been proven to suppresscortisol and I know cortisol is a big issue during training. I have been using 1000mg of vitamin C right before I workout. Usually in the form of some vitamin C chews from GNC (not a bad price actually). Been doing this for the past year....this has been the best year training of my career (Now Im not saying its because vitamin C). The last year I have added liver tabs, vitamin C and extra doses ofto my regimen.
