I just injected Deca and had a little Kynoselen in it. Pretty scary because the damn water base will not mix well with the oil base. Looks like tons of air bubbles in it. But it's just the stuff not mixing.
I would say that because of voulume it may not get into the system as fast. But really, it will get in one way or another. I would assume that it would seperate as well in the pocket where injected too. I would also think that the water based solution would be absorbed a little faster.
I'm not doing it again. I am just going to punch a few more holes in my ass. But really, it's in and will be used one way or another.
