I can't seem to find a definitive answer on what AAS cause the most acne sides. I know that everyone is effected differently from AAS and also that everyone's skin is different. But is there some gear that's known to cause more acne than others? My 1st cycle was D-bol/Test C with a little acne at end of cycle. My 2nd was Test Prop/Test E with the same. My 3rd was Test Prop/Test E/Tren E and had more acne than before. Was it the Tren? My 4th cycle is going to be D-bol/Sust 400 and I was considering using the rest of my Tren E but I won't if that was the cause. I used .25 AI e3d for each cycle. I liked the results I got from the Tren but I'll pass on using it again if it was the main cause of the acne. How's EQ? Any advice is appreciated. Thanks.
