also i wouldnt suggest "drying" the fent gel with a hair dryer 1)the heat could cause a drop in fent potentcy makeing doseing hard and verry dangerous if you were gunna cut up the patch's the ones w/o the gel would be best as it is easiest to dose thease but still dangerous and if your looking for a high you will most likely be disapointed hydro has a distinctive high when i switched from 7-8 10mg hydro's to 20mg oxy i would have to take 3-4 oxy's to equal what i was getting from the hydro but still i think the hydro had a better "high"
