So I ran my first ever cycle of sustanon 350 at 500mg per week. I ended up stopping after 5 weeks due to personal reasons. I took liquidex during this time. Here is where I will get criticized...I did not run pct. I didn't think I needed it after a short period of time. Now 6 months later I have shoulder acne that started about 2 months ago. I have never had this before and it won't go away. Is it possible this is from the test? I didn't get any side effects during the short cycle at all. I'm 28 so this is not a teenage thing. Any ideas how I can fix this and should I be worried?
