yea sure but watch for tolerance. low dose k works well and it is suggested every 10days to 2 weeks. i wouldnt go iv binging unless u have a shitload of k, even though once u ruin ur tolerance u wont feel the k, u may still get the beneficial antidepressant qualities, but i dont really know.
I would limit myself to like a gram of k every 10 days and try to sniff or IM it. of course, i am an iv addict myself, but i fucked up my tolerance to k and mxe.
