i ran it for a year straight. No MPB in my family but this combo sure did the trick, a few years later I just had a FUE transplant and i'll stay the fuck away from the tren/mast for the rest of eternity.
was i the most shredded i've ever been after a year of this combo? yes, absolutely. i looked insane and everyone in my entire life was accusing me of using AAS for the first time, there was just no way around it.
did i have health complications during this cycle? who knows. i was dumb and didn't do bloods for most of the year. i bounced back just fine but i'll tell ya pinning ED for 365 straight will drive you nuts. i only run 300 test / 300 deca now and 2 shots a week is a god send. having to pin ED fucked up vacations, long weekends, you name it.
the worst part was how emotionally distressed i became after months of running tren. everyone was commenting on how great i looked yeah, but they were also commenting on how big of an ASSHOLE i had become from the combination of drugs and dieting (i can get HANGRY and tren made it worse).
i will also say that after the first 6 months i really stopped making serious gains, i think that every cycle needs some change up after a period of time, or at the very least you need to give your body some kind of break, when you do you'll come back and realize you can make "more with less" in terms of dosages etc.
since then i've done great things with much lower doses of gear. tren is an interesting drug but in the end it was never made for humans and you can get just as good of gains using less "harsh" drug combinations. but to each their own, plenty of guys love and will always swear by tren. i'm done with it, forever.
