75mg ED I feel out of breath, sweat like a pig, sex drive comes and goes(yes, even with test), and I wake up 50 times a night.
100mg EoD and I feel damn good 80% of the time. As long as I get to bed on time(which i rarely do), I am just fine at this dose. This is my favorite dose and is perfect for me.
50mg EoD is a very low dose but you can still feel it. Its just enough to get the energy boost tren provides without the shortness of breath and low sex drive of a higher dose. Of course, the results won't be as good but I believe its safe to run it longer.
I love tren. It is the best steroid hands down, and I use it EVERY cycle.
