ok, i read somewhere (i forget) that sus can mess up your blood concentration levels b/c of the 4 different testosterone esters. also, i keep reading other people's posts and they speak of how bad the shot feels afterwards. so here's my problem. i have 8 amps of sus250. should i sell those (not to anyone on here) and pick up some test. enthanate and use that to stack with winny or what? just curious as to what others who have used these think.
