T3 is a thyroid hormone that is used in human medical field to treat HYPO-thyroidism (slow metabolism)
The PDR states that a treatment level is found by giving the substance to the patient untill a medium is found , usualy around 25-75mcg/ed taken in the am. but some people use it in doses as high as 125-150mcg for as long as 8 weeks.
I talked to a doctor that uses gear and he told me that if you run it at a dose higher than 100mcg that you should not run it for anylonger than 6 weeks , and to make sure that you pyrimid up and down when you go on and come off. Takeing it at higher doses and for longer that 8 weeks can cause perminent and irreversable thyroid problems , which meen that you'l just have to be prescribed the drug.
It is cheap (100 25mcg tabs is around 40$)
It is oral and redily avalible at your local street pharmasist
It causes you to loose muscle when take at high doses , so it is recomended that it be taken with some sort of AS
It stacks very well with ECA and Clen.
Any more questions , just ask
