I think if anything it would be the opposite, the dilaudid would overpower the oxy. But I’m not not very knowledgeable on how opioids of different strengths interact, or how they compete with each other for space on your opioid receptors. So my recommendation has nothing to do with chemistry or expertise.
My thoughts:
You obviously have some experience and some tolerance, given that you’ve had fun with dilaudid before. That’s not an easy chem to find, it’s been years since I’ve come across that on the streets. So you’re not a novice.
Even still, my advice would be to take them separate.
Not only for safety reasons, which is a big deal here.
But also because they’re both great drugs. Enjoy each of them on their own. Whether it’s an actual “waste” or not is semantics and up for debate, at least in my personal opinion. I mean somebody with the chemistry and/or biology knowledge may be able to give a factual answer as to whether it’s a “waste”. But I’m not that somebody.
I would consider it a non-scientific waste though, if that makes sense.
Take my layman’s advice for what it’s worth. If my answer even makes sense (I’m a little high right now). Be safe and enjoy!
