Clenbuterol – Fat Burning Drug – Doctor's Analysis of Side Effects & Properties

A physician’s analysis of Clenbuterol aka Clen and its side effects and properties. Clen is frequently used for its thermogenic fat-burning effects in a variety of sports and fitness competitions. However it has side effects that range from annoying, like “clen shakes,” to dangerous, like heart palpitations and panic that frequently send users to the ER. In some cases Clen seems to cause permanent heart rhythm problems. I also take a look at the evidence that Clen may be a muscle builder. If you are considering taking Clenbuterol or have taken it, please watch this video!

As the Anabolic Doc, since 2003, I’ve provided men who are using or have used anabolic steroids a confidential, ethical and professional medical venue to discuss their use. I do NOT in any way support the use of any performance enhancing drugs – PEDs, anabolic steroid or other medicine for muscle building or body transformation. The “off-label” use of PEDs, as such agents is considered elicit and may lead to adverse health outcomes. Please consult an expert health professional regarding any medical agent and do NOT use any medicine without the explicit advice and supervision of an appropriate medical expert.
