So a friend brewed up several compounds (mast e, test e, nan dec) with very low heat, standard BA/BB 2%/18%, and no issues at all. Made a thread a while back on tren A becoming a gum like substance, not going into solution, basically sticking to the beaker on both low and no heat, residual being unfilterable. The provider of powder offered that tren a needs to be brewed near it's melting point (roughly 200 F I think) as the manufacturing process is different and it produces some non estrified tren. This seems to go against what a lot of people are doing. I recall seeing Fina conversions done without heat at all...just basic solvents. Any guidance is appreciated.
