No point growing too quickly when the excess wait is gonna be blubber unless you want that to keep you warm, my friend.

I honestly think you have a very well thought out approach, and you're gonna be good to go. I've never worked with you and I don't know your body's response to estrogen and progesterones well, but I can say that with 800mg of Test in your stack, for most people there isn't gonna be any fear of libido issues. I'd still keep some arimidex on hand though, rather than rely entirely on Masteron for its anti-estrogenic activities. It's more of a side-effect than an actual main property of Masteron. But while you have estrogen covered, keep a look out for your progesterone/prolactin levels from Tren. Those might cause you dick problems if they go out of hand but nothing some caber can't fix. Half a tablet or 0.25mg 2x to 3x a week IF NEEDED as a start should do the trick. But with caber people tend to experience things like nausea and headaches and other uncomfortable sides so keep the usage as sparingly as possible.
