Very interesting, thanks for sharing! I’ve read that you can get your hands on a solution for Ketamine injections (or, if you have pure Ketamine, just prepare one yourself). Most go for intra-muscular injections instead (~70% bioavailability compared to IV, still great compared to ~10% when snorted). The reason they give is, when administered IV it wears off way too quickly – I guess drip solves this one!
This is, of course, way more risky and pretty much illegal I guess, but it should probably be cheaper?
It'll be significantly cheaper, and assuming you purchase the Ketamine from a reputable source/vendor and use a test kit on it, the risk is comparatively "minimal".
Not necessarily "condoning" the behavior, so much as sharing harm-minimization info here:
For safe/sterile injection, you need three things, all cheaply + easily available on the internet.
Only a little. Not enough to serve as an escape hatch. It depends on the infusion rate, of course, but you’re talking a difference of maybe 15-20 minutes.
How does it work? Is the half-life of it shorter when administered IV?
