Test deconate 250mg/ml in a 10ml bottle. Long acting of course, same ester as deca. Id never do this alone, unless you want to wait 4wks for your cycle to kick in.
Way better off with enanthate (Loeffler makes one tetoenan250)
its worth useing but i dont think its really 250mg /ml i once run 500neo with 750test didnt do much better than straight test a little but not much the next time i used it i bumped it up to 1g with 750 test then it worked well so i do belive its under the amount said on the bt
