How bad are you breaking out on shoulders and chest? Some people break out worst during cycle, some only break out in PCT. Some will all the way through the trip. As long as you don't mean like 20 pimples on your chest and back, I'd say it's normal. I've only had one pimple on my back in the last year. Came from a Helladrol cycle, oddly enough. Could have been coincidence. I am 27, but still youngish, I feel, physically.
