I am 31, and have been lifting weights for over 15 years, due to playing sports through college. I decided to get a little more serious and started my first test cycle recently. I am in week 5 of an 8 week cycle (nothing too crazy either, just a beginner cycle from all I have read on here). After a real heavy shoulder / chest day, I woke up the next morning with EXTREME shoulder pain and chest tightness to where I could not take a deep breath. Has this happened to anyone else, or has anyone ever heard of this side effect?
