Can anyone help me out with which supplements work good? I have been lifting for a year. I currently take creatine, whey protein, ABB energy drinks, and Leukic. I have had some great results from some Muscletech products. Gakic definitely works. Cryotest is also good. However I stopped taking these products due to the high caffeine content which gave me "jitters." I am thinking of trying Muscletech Celltech creatine. Has anyone tried it? I know it is expensive. Is it worth the money? Leukic is garbage and hasn't worked for me.
