I have much better luck with Tren Ace. I dont have much Tren experiance, I'll state that up front, so I got some of each ester to see what suited me. I have yet to completely run a Hex cycle, cause the side effects were too in tense for me, no matter the dose, mostly the night sweats. Currently I am on Tren Ace, and no night sweats, but a little trouble sleeping at night. I wouldn't call it insomnia, I do get "some" sleep, but it's not normal. Only drug I have ever taken that Ambien doesn't work to get me to sleep either.
Besides the injections for often, ace any day over the other esters, injections dont bother me near as much as the night sweats, acne, and shortness of temper, I get none of the above on Ace, and if I switch to EOD injections, my sleep patterns are much better also, before you ask I am basing this on 75mg injections ED or EOD.
