2 months??? That's kinda long buddy, no? Aside from the shutdown aspect, what about you kidney's and liver? No problems/are you getting bloodwork and making sure you're not ruining your health? NOt trying to preach but that seems like an awful long time to run tren 6-7 weeks (I have heard guys going longer) seemed to be the more cautious route.
BTW, 50 mgs is less then what most suggest even for ed, not bashing flaming or giving you any kind of shit. Just wondering have you used it at higher doses in the past or at all?
I'll also agree with what has been said so far. For your purposes I'd day tren, more test and decca would be great. Dbol has a decent chance of putting you over the weight you want to be at for your comp. (at least for me it's been a drug that puts on 5 lbs or so AT least even when I'm eating clean so you'd have to be really strict with your diet). And winny imo is a terrible idea for many reasons but in your particular case I seem to notice a continuing correlation between guys who use winny and hurt themselves while on or after they're off due to how brittle it makes your joints and tendons. It a shitty AAS.
