I go as low as 5mg/day (35mg/wk) for long cruise periods, or even during blasts where I don't want tren taking up a large percentage of my total AAS load. For the high end, I typically don't go above 30mg/day, or 210mg/wk. I have experience with much higher doses in my younger years, but am now of the mindset that a little goes a long way with tren. I was a former acetate fan, but now I'm an enanthate only user. Nothing wrong with ace, and I don't necessarily believe that flat line blood levels are all that great an idea with everything, especially test, but with tren I do prefer longer esters (enanthate or hex) and more stable/flat blood levels.
