I started to write a response, but since I was not familiar with the medication, "Clenbuterol," that you had been taking, I did some quick research and was surprised at the information I found.
What follows is that information:
Clenbuterol side effects: Clenbuterol may reduce, not enhance, performance, and stiffen heart muscles.
Clenbuterol is a popular - but banned - drug used by athletes in body-building, power-related, and even endurance sports.
