Fina is short for finaplix - a cattle implant, not oral tren.
All acetate esters have some kind of oral bioavailability however, but there is an oral version of tren called methyltrienolone. It's some pretty nasty stuff apparently.
I want it to be there. i ordered a steroids piss test that u send to a lab just to put my mind at ease about my sustanon and tren e. It's supposed to tell you concentrations and everything. I know it's not blood but if they are both thru the roof I think if relax a bit. It tests for 11 common steroids but I didn't see tren or fina on there
