I'm willing to bet creatine and "antioxidants" only have placebo effects too :o)
I'll take that bet sir.
Creatine monohydrate is the most researched sports supplement on earth, and has been proven to increase strength and resistance to fatigue. Go read the hundreds of papers and studies, for yourself buddy. O and by the way it is produced in the human to do that same job. You do however need to drink alot more water than normal if using creatine to get the benefits. IA common mistake is not to increase water intake and therefore dehydrate and you see or get no benefit. Note: It will not work for everyone its about an 80-85% hit rate with people. Normally 5grams is used and loaded for the first week to ten days, it has been shown though that 20grams or more each day is still safe and does give even bigger gains.
Antioxidants, come on buddy you must know at least some chemistry and biology. Exercise destroy's muscle to create energy in that process it creates free radicals which we are bad little buggers and make recovery longer after you have finsihed excerising. Using a strong antioxidant helps remove those free radicals by binding to them and therefore reduce muslce break down post excerise and aid recovery.
Of course with everything there is a level of a placebo effect, but in these cases there is a really measurable effect also.
