A much, much more physically intense, energetic and forced experienced. Instead of a body "stone" of comfort, it has waves of rushy, tingly pleasure that makes you want to move and act in ways you normally wouldn't
Pretty unique, but if you have any experience with other amphetamines/meth you'll recognize straight away how they're distant cousins. You're very aware you're on drugs. It has this inauthenticity to it, hard to describe and not so spoken about.
And it fkn comes and goes as it pleases and when it leaves for good it's really disappointing (ime).
As you would know oxy feels more like you just happened to be having a perfect day and "Everything in the world is A-Okay and this is how life should always feel!" - very natural type of feeling. (If you're lucky, briefly, fleetingly.) Doesn't feel like you're on drug drugs.
