im always amazed by ppl who give advice without actual experience.. but that seems to be the new thing.
i have mixed water and oil in the same barrel plenty of times, b12, glut, sod i think even peptides into who knows what variety of aas and other oils. by and large it just becomes harder to inject and maybe it hurts a bit more then usual.
as long as you are injecting good clean things there is no issue. i have even injecting things that are questionabley clean and even then no real issue, just a lump and soreness for a few days.
if you try to run oil/water combo through a slin pin that is slip rather then luer lock it often pops the pin off. which for those who dont know is also a wierd thing as you are left holding the barrel in your hand the pin in your whatever and oil water smelly mix dripping down you.
that happens often with 29s, heavy mix and heavy hand. luer lock fixes that as does using bigger pins. i use 21 for a lot and oil water even a cc of each in the same barrel go fine.
i have used water based gear and water based other stuff plenty of times too, plenty of times doesnt mean a handful of inject but years at length.
the guy with no experience is quoting stuff out of magaines in a time when mex gear was what most used and much of that was not the highest quality. i have used water based antiox that are years old in btls with ripped up stoppers with rubber floaties in them and still no scary infection or horror stories.
so thats whats REAL not what i read somewhere from some guy who maybe did this 20 years ago that was written by some guy who probably didnt even talk to the first guy face to face in the first place. at least i got another post of it!
