whoah, 700mg Tren Ace a week? I can understand 875mg Test ENANthate a week, but that's a lot of tren for an apparent first time tren user... maybe 50mg Tren ED for starters? That way you get 1ml with both mixed.. nice and efficient, yes?
Test Prop at the start would be a good choice combined with the others, as remember that Tren Acetate will build up levels quick, while your Enanthate will be well behind it, allowing the onset of poor sexual function, if you're one of the many that experience this from the heightened progesterone from Tren. Test Prop would shadow the Acetate and you'll keep wood that way.
ED injects is indeed a good way to go with Acetate, and why not with the Enanthate, it alleviates the chance of sides even moreso.
Run the Tren Ace for weeks 1-8, keep the Test E going weeks 1-12 with PCT at week 15.
With prop weeks 11 1/2-15 is what id suggest as well. Start PCT 2 or 3 days after last prop injection. Thats what id do personally.
