I would say that most people with back pain, neck pain, hip pain, etc. take from 5 days to 2-3 weeks before they start seeing results. It seems to work on some other things (like seasonal allergies) in 2-4 days, but most people suffering from chronic pain for a long time need a higher dose (~9 mg/day) and it typically takes a week or so to see major improvement. But, I guess it varies greatly from individual to individual.
Good Luck...spread the word (both about Anatabloc and STSI as an investment).
