i know usually its as long off as on. is it the same if i plan on doing a 4 week m1t/4ad cycle, 3 week pct (7 week total), then wait 7 weeks and start a sd/m4ohn cycle? or should i wait longer or can i wait shorter before starting the sd cycle? m1t cycle gives me more size than sd, but sd gives better quality. so this is kinda an experiment to see what the results will be from doing an m1t cycle and not that long after pct doing the sd cycle. i know the negs of m1t and the negs of sd, what i dont know is what a semi-short time period between the 2 may do. i know sd and m4ohn are both methyls, so no need to preach about that. i also know all the 'preventatives' to take with each cycle, so no need to post that. unless there are others that i should take because of the short time frame between the 2... whats your thoughts?? ill definatly post a diary if i decide to do this. max
