I wouldnt risk it cuz 2map collapse veins first try from the reports ive read. Yeah i hear that is less caustic but how much so? Maybe try plugging some first real dilute and see if it burns that way you can evacuate bowels if need be. And if you cant handle plugging it i would avoid the mainline. It's not worth it when something like Etazene is around that is safe to inject...
AP238 from my experience was even more caustic than 2MAP.
I took some AP238 sublingually and it literally dissolved some of the soft tissue under my tongue. I was spitting out little chunks of flesh. It hurt for a week. Do not inject it, i cringe at the thought of that stuff entering the circulatory system.
