I am currently pinning Sustanon eod along with Tren A and Masteron ... I have always used Sustanon except in my TRT when I use cypinate...my question is there any advantage to using one ester and pinning less often as far as consistent test levels? I donít feel a lot of up and down but if thereís something to be gained I may consider a change, Sustanon is kind of an old friend Iíve always deferred to
