If you have done a couple of test only cycles then i think adding tren e @ 250mg a week would be good.
I think the sides are over hyped especially if running a low dose. You might get a bit sweaty at night and maybe find sleeping a bit rough at times. People also talk of increased aggression but i would describe what i experienced as more of increased irritability. At 250mg a week you might not got any sides at all.
I think some people find that mast can increase aggression just as much as tren.
That mast blend would work but obviously the 100mg or prop isn't going to be stable but i don't see why that would really be an issue
