How many mgs of DXM are in eight 4 oz bottles of robitussin?

Question

just to confirm.

I've worked out that one 4 oz. bottle holds 60 mgs of DXM (i have no idea if thats accurate)

so 8 bottles should hold 480 mgs. (again no idea if that is right)

can anyone confirm this for me?

Answer 1

Totally wrong. 1 4 oz bottle should have have about 15 mgs per 5 ml. something like that. i dont remember exactly what, but i have worked it out for one bottle to contain about 360 mgs of dxm. 8 bottles could kill you. Make sure that dxm is the only active ingredient in the robitussin.
