try and only do 3-4 short 6 week cycles a year. stay off for the equal amount of time if not longer. most people are uneducated on cycling and do more long term damage than good. Post cycle therapy and time off is the only way to insure that your naturally levels will ever be normal on there own. No one wants to become testosterone dependant for the rest of there lives, i would imagine. Unfortunately most abuse the drugs readily available today and , wether they know it or not, are most likely testosterone dependant. The only way to ensure proper cycling is to get regular blood work and sufficient off cycle time, and dont get back on until you have got your natural levels back up. I only speak on this becasue I myself had fallen into the long cycle trap, and l thankfully was lucky enough to be able to keep my naturally levels up, of course it took long term use of heavy doses of hcg, clomid, and bromocriptine to make this happen. One other thing, if anyone plans on ever having a kid, count the idea out if you stay on for long periods of time. I am going to the fertility doc on thursday, and I can only hope for the best and pray that I have some fish still swimming.
