I want to start running but the thought alone of running already makes me tired. I went to the Vitamin Shoppe to pick up some supplements but was overwhelmed by all the different types. I saw a supplement at the vitamin shoppe called N.O Explode it looks pretty popular and says it can help give an extra push when working out. I also read that it makes veins bulge, muscles grow and contains creatine. I do not want to bulk up at all i want the opposite i want to slim down and become more defined would it be a bad idea to use this product to run? Does anyone know any products that don't contain creatine, stunt growth, increase mass or increases testosterone level which can help give me an extra boost for when i start running? If anyone one can help please let me know
