take one small hit for first time to see if it's bad for you or gets you asthmatic. two spaced hits is recommended since my first hit had hit me like a truck but the second hit was great and if the initial hit was my reference I would have thrown it before.

you shouldn't do it if you have some kind of heart disease.
they say that moderation is king, I didn't do that and just sniffed it a lot but after about half a year since started my tolerance became lower and maybe due to that is why I get (very hard to breathe) bronchitis of sorts and mucus after 3 hits (about 0.1~0.2ml of a glass pipette on paper in jar is good for 3 hits) but I just think the last one I got was cooked in transit (ordered during hot summer delivered by a biker) and fresh ones may be better (so maybe only order them during winters or when weather is cold).

in general you should avoid isopropyl and shady chinese imitations. real ones tend to have those safety caps with cap liner (usually cardboard with PET or aluminum)
the vision do get fucked after use with amyl (was hitting it a lot in span of weeks directly from bottle!) but it was only very temporary and due to change in pressure (it's a vasodilator after all) make sure to get amyl brand and you'll know it is real when its bottle closure liner falls apart after some use.

also back on the bronchitis thing it is more of a mental thing I think. the first I've been hitting it too much (40+ sniffs / sesh / >2hours) I only got stuffy nose (never burned skin) and proceeded huff with my mouth, later my lung issue developed (possibly to save me) but it was mental as in I could sniff poppers and sleep immediately after a goon sesh - no airway tightening and immediately upon waking up I start to get what seems like asthma so it might be some kind of withdrawal or my body rejecting poppers? the recommended thing to do is to spit out the phlegm. treat every sniff like it's hot water, you can get burned if you do it too much!
