yeah i thought spiro were 2 micrograms each. i would start with one the first day, then up it everyday until u feel good about or u start tweeking out. some guys can take atleast 10 a day, 6 is my max so far before i start shaking real bad.
Most spiropents are 20mcg or 0.02mg. An effective max dose would be anywhere from about 100mcg to 140 mcg per day. Like the other guys said, alot depends on the individual. A common method for clen is to start at about 60mcg/day and increase by 20mcg per day until your max dose is reached.
