I did a similar one recently with 200 Test C, 280 Tren E, and 400 Mast E with aromasin for AI and 1/8 mg caber EOD. It was good in most ways. No sides to speak of, in terms of usual tren sides like night sweats or fits of rage - but see below for others. Gains were slower than I would have expected, but steady gain of muscle and loss of fat. Was able to hold on for 11 weeks, which I hear for tren is a long time.
Blood testing showed estrogen at 25 on sensitive test and prolactin at 9, so controlling those was spot on. Only downside was I decided to throw in 200 mg/wk deca for joints and toward the end was hit with a bit of ED, so I stopped the 19-nors right away. I've been detoxing now for three months and everything is working fine again. I don't know what my future with 19-nors will be at this point, but I sure won't ever mix tren and deca again.
There was some tendency toward muscle cramps, so I made sure to drink plenty of water, take magnesium, and taurine to keep it manageable. It mainly hit when I extended hard to one direction and held it, like twisting around to stick a needle in your ass or holding a tough stretch. You learn to be careful and relax when doing those things.
What is your body fat? Your doses all look reasonable, only thing I might say is some folks recommend 600 mast. I decided to go 400 to try to keep cramping to a minimum.
As far as other sides, tren drove my liver AST and ALT to the highest I have ever seen them, even with milk thistle and NAC. Also caused my blood pressure to be very high, and couldn't control it with hawthorne berry & fish oil and a few other supps. All in all I can't say that combo is any better than test + boldenone + deca, but sure has worse sides.
