I find that I tend to get acne from tren more than other gear. As much as it can be a pain to do ED shots, I find that doing so stops my acne. With ED shots, hormones are more stable and often with gear, it's hormone instability that causes acne break outs. Also, be sure to keep your skin clean. On gear, especially androgens, you're more likely to produce oil. When your glands are pushing out more oil, you are more likely to collect bacteria on the surface of your skin and get clogged pours. So cleath clothes, clean sheets and pillow cases, shower at least 2x day. Do everything you can to keep oil and bacteria at bay. I would also suggest using dial anti bacteria soap.
