They are great to order from.
Work your way up and down the entire time on the dosing. I would not alternate, that might spook your thyroid (just a guess, no science on that). Start and end on one pill a day.
There is a really long thread in the forums called "Tri-max" or "trimax" by supersoldier, it is a good read, about 11 pages. I think he gave it to his girlfriend, and it talks about what to do after you finish so you don't gain all the weight back.
good luck!
