Well, I'm not sure why you're overly concerned about this. I mean jesus christ dude, you almost died. Stick to the low dose, get your feet wet and then up the dose again.
I was 245 in November, probably around 14% bodyfat. I haven't touched ANYTHING since then due to some personal reasons, and now I'm right around 250 and 17% (haven't trained/Mcdonalds/low test).
It fucking sucks. It really does. If you stick to the low dose, you'd probably get back to where you were, but it would just take longer. I'm about to hop back on at about the same dose, cruise for a month and then add in some tren/orals.
You'll be back in no time, man, just give it a little bit of time. Good luck!
