I ran a Tren Ace/Test Prop blast once before trying Tren E. The sides on Tren E were more intense for sure. Of course when I ran Tren E, I ran lower Test Cyp at about 300mg/week. When I ran Tren A and Test Prop, it was at equal levels (100mgs both 3x week).
I do believe sides are less with Tren A though, because it's a short ester. You don't get the compounding effect of the Enanthate ester.
If I didn't see hair loss., I'd probably suck it up and run it again.
