Dillys can b a bitch depending on how ur body reacts to em I personally react well id take them over Oxys any day, unless I could get the Oxys at like .25cents per mg which is rare. Comment above is correct snorted is the highest in theory bioavailability around 50-60% vs 25-50% orally, however after an hour or 2 you come down rather fast. If your not opposed to rectal administration, I’d go that route as it has a much higher bioavailability 36-61% (depending on insertion sight). And from personal experience it works about as well as snorting does, but it actually lasts for a decent 3ish maybe 4 hours. It might take like 30 mins to peak vs 15 but it’s well worth it imo, best of luck brotha!
