What dose are you on? (self-reported, unverified)
Read this first. These numbers come from anonymous visitors typing in a box. Nobody checks them. People misjudge, mistype, troll, or take untested products of unknown strength. They are not a dose guide and never override the sourced table above. They exist only so the sourced ranges can be compared with what people say they take. If you are deciding what to take, use the sourced table, start low, and read the risks section.
