I have always wondered about blasting cycles.....specifically like running 4 weeks of Prop or TNE with Tren, Winny, Mast or something else fast acting. Running a quick little PCT, and then getting back on.
I usually run about 2 cycles a year, and lately have been preferring longer cycles like the 16 weekers because it is more time that I look huge, and its easier to maintain the gains because your body adjusts over the longer period of time. That said the 2 cycles don't both finish in the same year, one will probably finish in the next year so i couldn't give you a total amount of weeks on. I wouldn't count the esters clearing and everything with regards to how long i stay on in the year, but i obviously see its purpose and understand the amount of time to stay on/off.
