Primo and anadrol.
i have heard good things about this, although i have never done primo (the only anabolic i have never done).
my response is there is no replacement. i have never felt anything like tren in my blood. i love tren. it doesn't make me crazy like ti makes others. it makes me insanely confident, and it shrinks my waist and adds real muscle everywhere that i couldn't add it before (rear delts, the top of my triceps, etc').
