i dont know if this is true but i have read that extended period use of nolvadex should permanantly reduce slight gyno. i think next time if you use EQ instead of deca you wont have this problem. well, at least this is true for myself.
i used to get similar problems after a heavy cycle with test. i used to also get paranoid. i would think people were after me and sometimes i would flip out on someone cause they looked at me in a certain way. it was only temporary. with the boner thing, usually a few weeks after the last shot...
you know whats going to happen. your going to be in the gym doing your workout as usual but then BAMM. your muscles are gonna get so pumped that your afraid your gonna rip your shirt. thats how it is with me. it creeps on me all of a sudden. i love it!
if i were you i wouldnt wait to have sign till you start using nolv. start using it from day one and be safe. it may hinder your gains a tad bit but nothing worth risking getting fucked up.
