Not so sure on the salt form with the trihydrate so def double check that but..
plugging is def the way imo, great BA and past silly stigma is a effective and easy way to use the form you’ve got.
I’d stick to 1AMP with no tolerance, maybe 2-3 if higher tolerance but not higher as your risking messing up tolerance then causing dependence from such mega doses.
If you really don’t want to plug, if the ampuloues are 100% pure and the salt form is safe (likely is but have to ensure I don’t give bad advice) you can just chuck in a drink and swallow but with terrible absorption of 30% to memory.
Drying into powder to sniff is worse from memory, even more pitiful absorption but can’t remeber if sulfate or hydrochloride have differences in absorption intranasally.
If hydrochloride does have superior absorption, you could see about drying into powder but no idea how to do it, plus with such a small amount unless doing multiple amps, and if it mess ups your nose… eh..
Wouldn’t recommend IM or IV when plugging has such good results, and the rush is apparently compulsive from injecting, plus the plethora of issues from injecting itself.
I know with proper equipment, drug and technique you can keep yourself safe but it seems plenty of hassle compared to sucking up a lessened rush, for near same absorption and less potential issues.
Cyclzine, DPH and Promethazine can potentiate but aren’t really safe imo due to dirty pharmacological profile, but once in a blue moon at sensible doses is probably fine.
Any other combos with depressants, is unsafe..
sensible dose caffeine, or pharma stims is nice to make it more functional.
Else low THC high cbd weed is a great way to push the buzz. To high THC ruins opioid highs for me.
