I'm wondering that myself, only phen I have at the moment is 2c-e. I'm not sure how well that would lend itself to IV-ing, like, I could see the stimulation and bodyload being very unpleasant. Might make the time frame a bit shorter though, I dunno, I'd consider trying it just to try it. For me, tryptamines can go negative rather easily (when I'm dosing them orally), and this first attempt at the IV route worked out rather wonderfully, and I can see it becoming my go to method of taking them in the future (I'll have to get some DPT this summer maybe) when I want to spend a quite night in, though orally would be much better if you want to go outside and walk around and just have a nice pleasant day, though I'd rather have a PEA for that purpose.
