I always use patches transdermally or IV, had a 50mcg/h one not long time ago,sometime these days. Not with the gel but with the Polymatrix system, I only wore the patch this time but probably gonna shoot some in the nearby future, shooting less and more frequently is a good tip so to say, but the question is how frequently? Careful, be mindful regarding the half life of fent and get some narcan.
The patch on approach has worked for me too, but I OD'ed twice wearing a patch and shooting it at the same time so I wouldn't recommend it that kindly.
You got it in powder form? How did you weigh it? Some additional info would be much appreciated
