If you pick the right chems your low metabolism won't be noticed I would say stay away from estrogen conversion drugs and pay a lil extra for the clean lean mass builders like anavar , Winny, primo, para, proviron, mesteron, tren ace but I don't recommend that right off the bat ..... best is to do 500 test and add a highly anabolic non estro conversion like Winny and add in mesteron or primo at a high dose......
