Exactly Fish, what makes 800 IN your blood magic? If I made the OP some chocolate chip cookies, and he loved them thinking I made them exactly according to recipe, but then found out that I used only half as much sugar, would that make the cookies taste worse than they did before? Point is OP, you will make some awesome gains off of 800mg/test cyp, hell, you'd make awesome gains on 500mg/test cyp as long as your diet/training are on point. This is your first cycle isn't it? No offense shamrock, but you are way too zealous about the gear at this point. You've already decided you are going to use, so now be wise and start off low with only one compound. If I could change anything about how I started, it would be starting out with test only at 400mg/week. Second cycle would have been exactly the same. I would only up the dose if I didn't make any gains on the 400mg. I would only add in one extra compound at a time and only if my gains at 1g test (after many many many cycles) stalled.
Slow your roll bro. I like that you are really seriously considering how to do this best, but you are missing some key things in your excitement.
EDIT : Ok, just read that this is not your first cycle, but it IS your first one in 5 years. Understanding that, my advice does not change.
