apparently its similar to oxycodone but worse side effects and unknown effects seeing as how its a completely different molecular structure than traditional opiates or even fentanyl i personally wouldnt try it as a substitute unless you fancy being a lab rat just to save a few bucks for something you might not enjoy as much as the real deal and although it may scratch the itch so to speak i would still rather get oxy30s even if it means i get less high at least i'll know what i'm putting in my body and how the wd will feel
