scotch~ I dont think theres one right answer. Everyone is different. If you read the testimonials in Tom's book, theres a guy who was a 4th degree black belt martial artist who was running 5k cross country races who cleansed for 28 days and gained 8lbs of muscle!! Now thats not anything close to me, but like I said everyones different!Ya never know whats possible. Get in~tune with yor body and you should know what your able to do!!
