I've just started my first tren cycle, and it's tren e. While combing through the boards collecting info on tren, I REPEATEDLY read from those who have tried both, that ace tends to be MUCH harder in terms of sides. Many report that they get nasty sides on the ace and very few (and less intense) from enanthate. That, and the fact that I want to limit injections, has led me to try tren e first (at a conservative dose of 200mg weekly).
