First cycle of clen

HELLO fellow gym freaks im 18, 75kg i was just wondering what i should start my first cycle of clenbuterol dosage at, should i begin with 20mcg per day and then up it by 20mcg each day until i build up to my max tolerance, then stick at my max. and is it alright for me to run my cycle for 1 month on, 1 week on 1 week off?? im not running any other anabolics.
