I was in a bad car accident about 5 yrs ago & Iv been perscribed every pain med from percs to roxys to oxys to methadone, & now i wanted to give MS Contin a shot to see if it helps more with the pain. I wanted to know what Brand Name MS Contin has the highest potency. I am on the generic 200mg pills made by Endo this time and they arent too good. I am going to get name brand next time & wanted to know if anyone that has been on the 200mgs know which manufacture makes the highest potency brand name MS Contin. ??
