Short cycles are not for everyone, and certainly not for guys who compete. It's more for people who more concern with their health and reproductive system.
The idea behind short cycles is that if steroids are used for not longer then 2 weeks, and by day 15th body is cleared from synthetic testosteron, only hypothalamus is suppressed, but not pituitery(in a matter of fact, it gets more sensitive) so the postcycle recovery is much faster then after 8-12 weeks cycle.
Of course, short cycle result in less gains, but it's much healthier and because of fast recovery practically all the gains stay.
A lot of guys, especially when they get older find that short cycles work very well for them, usually resulting in 4-8lb of keepable lean muscles,and it's not that bad.
The formula is 2 weeks on, 4 weeks off.
Usually user frontload with slightly longer ester(day one) and then keep using fast active compounds,like orals, prop, fina,suspension.
