Help with cycling clenbuterol

[toothache]

Does anyone have a study to show that 4 days on and 2 days off actually works? I've never seen one. Not saying it doesn't work but I would like to see the actual study. Is 2 days enough time to up regulate the receptors? Half life of clen is 36 hours. Is 2 days off enough time?

i've done 4 days on 2 days off.. in my experience and the other 20 bodybuilders i kno that do it around here all agree that it wrks. 2 days was enough for me... but clen like any other drug... ppl body react different to.. it could wrk better for me not for sum.. but if 2 weeks on 2 weeks off isnt wrking for sum1... why not try another way?
everything here are basic guidelines everything should be tweaked in time to how ur body reacts to any drug u take.

2 weeks on 2 weeks on isnt an official way to cycle clen... its a great way to start coz its mild and cheap.
