Yes I did. Well with 0 tolerance 2mg of bupe sublingualy made me high as fuck, too high in fact. And while without tolerance other opiates (H, methadone, tramadol, opium, morphine etc) hit the sweet spot for me at pretty low doses, probably lower than what most people need, with bupe something's really not to my liking (in various way). And when I tried snorting it, recreational potential was a bit more there as it was easy to titrate dose but by than I tried quite a few opiates that I liked a lot more and as one my friend said (opiate lover who never got addicted and did try it snorting with absolutely 0 tolerance) - "first time I got too high (puked etc) and second time I found bupe more of a reminder what I could feel than real good feeling".
Of opiates I mentioned only one that I don't find superior to bupe in just about any way is tramadol. And even that's more or less only cuz I don't push tramadol high while with 0 tolerance I prefer it. Since I started I'll name other opiates I tried too. I also tried oxy (only 20mg or so, with morphine tolerance but still liked it for being uppy), butyr-fent (kind of feels how I thought fent'll feel), MT-45 (bitter and strange), AH-7740 (not too strong but cozy) and fent patch (a lot shittier than what one would expect from Americas #1 opiate). Out of those I guess I like bupe more than I did MT-45 and I find fent about as shitty as bupe, just in different ways.
This is only my preference and different strokes for different folks apply. Iirc bupe was third opiate I tried and what I do recall for sure is that I loved it and fed myself with similar ideas about it. Also when I say it's shitty, that's relative.
All in all, if you love bupe, might be best to stick to it on rare occasions as while there are those few who for some reason love it even more than H, those are far in between. Reason i wont say, definitely stick just to it, is that bupe and bupe alone is capable of destroying lives. And if you gona fuck up your life cuz of opiate high, at least make it worth it.
O yeah, if you are in USA, than yeah, definitely stick to it, rather than doing street dope (which judging by my pharma fent experience is anything but worth the risk even if it was free).
