hey bodybuild4life, why are proud you have more tolerance to DXM? Im happy taking 450 mg doses, i tried 600+ and its was too much. Ill try it again later(once next month?). i take DXM w/ moderation, i dont want to build tolerance and i certaintly dont want to end up like some losers that take it everyday or every other day because, in my opinion, that will fuck you up physically and mentally.
