I am able to get some 75mcg fent patches for $40 each today, I have never done fent...is this a decent price??....also, they are the non gel ones and I would be chewing them I guess, whats the best method for this? and how much should I chew and for how long????I searched the site, but everything is about smoking the fent.....so whats the deal peoples? should I buy em? or wait for some oxy?
