I'm a more or less AAS newb, so take this for what it's worth. A close friend of mine (former professional fighter, and current trainer) runs his tren cycles like this. First I'll say, he runs tren for everything, bulk, or cut, the amounts of tren is changed depending on the goal. For a bulk double the tren to test (or more). The test is only ran to keep sex drive functions working. So he runs it at a slightly higher then trt amount at 150-200 mg a week. He'll then run tren 400-600, which he said he's ran it as high as 900 hundred and found very little benefit compared to 600. The sides were much greater, and the benefits just didn't balance it out. During a cut He runs 400 tren/150 test and will throw in Mast once the bf is below a certain level. During a bulk he'll do 3 days of cardio (low intensity jogging swimming). On a cut its HIIT 5 days a week (skipping/sprints/sparing). He felt that the test at as low as it was wouldn't be a problem with aromatising, and the tren would somewhat take care of it. So taking care of prolactin and the consequential sides would be the issue. I believe he runs both caber and prami, I'm not sure the mg's but I seem to remember him talking about tapering both of them. The guy is ripped, and hits like a ****ing truck, so I mean, in some regards I can't argue with his results. The former boxer/mma in me sort of wants to emulate that, but I've fell in love with picking up heavy things and putting them down to much to go back to voluntarily getting punched in the face. Just another option, and maybe some food for thought.
