Right now I've been on for about 1 year and 10 months. Taken a three week peroid off and a two week period off in that time but I don't consider that coming off since it was such a short peroid of time. A lot of this time has been one drug at a moderate dose for cutting or just maintaining. Currently doing a 1800mg test cycle that will last another 8 weeks then I'm coming off...so that'll put me at 2 years. ugh....
