I'm on a sust/deca cycle. So I went to Miami last week and prior to, I had my chest and back waxed. So, the 3rd day, out of NOWHERE my back broke out. I'm talking like 100 pimples in an hour. I didn't know if it was from the sunblock or what. It is still pretty bad although it dried up a little. I NEVER get acne I usually have really clear skin. This is my first sust cycle. I usually run test-e/deca.
Is this an allergic reaction or what? What causes this? What can I do to stop it and in the future to prevent it?
Thanks!
