I've read here many warning about the potency of fentanyl.
I would share first-hand experience about the topic, HR-wise
My tolerance is close to zero
1) Transbuccal fentanyl
I cut a piece from a patch and put it on a gum.
I use 200-500mcg. I think that 1000mcg would give me nausea. From this doses I get an apparent but not strong myosis
With patch usually 1cm2=400mcg. A 25mcg/h patch usually has 4mg of fent in it and it's 10cm2 wide
I've done this with two different brands of patch and with blotters, the result is the same so my figures should not be linked to a specific brand.
2) Intranasal
I put the blotter in a syringe with 0.5cc of water, then I spray the water in the nose.
This I do with 200mcg, you need about half then with the tranbuccal route
