pertaining to fentanly patches?

[bettertedthandead]

so SWI've got a 75 patch. SW'Im a pretty experienced opiate user i guess. SWI've used oxycontin regularly for a few months, every 3-5 days or so, at least forty sometimes more than eight mgs each time. SWI've tried china white once before too, a pretty significant amount for a first timer so ive heard, three lines in about 2 hours. but still SWI'm a bit pensive about using thus patch thing due to the differing opinions SWI've heard about it. so SWIi would like to know the best way to go about doing this. how much to use at first, the most effective way and the safest way to do it without od'ing. help SWIme out here guys!
