Fentanyl Patch (Gel) how to get highest-er?

I looked around the forums and it doesn't seem like there's as many heroin users and fentanyl users as the other forums I have been on.

But if anyone knows or has any experience with Fentanyl, I can get them now and have been because my Heroin dude has been out and no good dope has been around. But anyway, I don't know how to get the most out of the gel. Everyone smokes them off tinfoil, but I have been reading and I keep seeing putting them on your chest after shaving really hard, almost to the point of bleeding, then using a blowdryer on it.

The heat releases the gel quicker into your bloodstream, but I've never done this. I always just smoked them because it was the best way to get high and it was simple, but I know the bio availability of it is really low. Just like smoking OC 80s and stuff, is stupid. The bio availability is like 92% if you put it on your arm, but it's such a slow release into your body.

I know a lot of people have tested the best ways to get high off of the gel, so does anyone know what the most effective way is? EAting the gel, or smoking it, shooting it, or putting it on your body?

Any info would be awesome
