m18, in my opinion u should run it for 20 days, break 1-2 weeks and run it 20 days again....it seems up to around 20 days the fat loss in constant despite dosages(interesting isnt it) meaning that if u take 200 mg for 20 days or 600 mg for 20 days u'll still lose roughly 20 lbs of fat (probably has something to do with ffa's)...anyway ive read a few posts on cycles >40 days and it seems that fat burning effects decline like 40 days, 28 lbs fat lost....this is just evidence based on other people's experience, but it seems it would be more effective if u divded it into 2 20 day cycles. Plus some ppl get really bad sides >20 days.
out of curiosity, have u had this dnp for a while?
