Methyl stim powder. No jitters just amped in the gym non stop. Have to keep track of time or im there for hours. Good feeling all day. No crash till bed time. Good stuff no need for more than one scoop
BTW its by pureline. Also has some "test boosters" in it if you like that kinda thing. An some of the ingredients are the same as the old jacked formula. No face burn or itch though.
