There seem to be a couple schools of thought regarding this.... Some members wouldnt run for less than 8 wks, while others may feel that 80mg ed for 5 wks would be ok too. My opinion highest dose you can run with the amount you have for 6 wks. Thats just my opinion, you'll need to know how you personally react to var. Other more experienced members should chime in and help you out. lots of good info here, keep asking questions.
