Clenbuterol PCT – Side Effects of Clen and What’s a Clen PCT?

Clenbuterol is a PED (performance enhancing drug) that is used by a number of athletes and bodybuilders in order to increase their physical appearance and athletic performance.

This is not a steroid. That means that it is not a derivative of testosterone or DHT and is instead a substance that is used to increase cardiovascular performance. It does this in a number of ways, predominantly it acts as:

  • A beta agonist – A stimulant which increases the activity of the brain and thereby elevates the heartrate, like an intense version of caffeine
  • A bronchodilator – A substance which will increase the amount of oxygen you take in with each breath by increasing the size of the small vessels in the lungs

The result is that you have more oxygen in your blood, resulting in better delivery of energy and nutrients to your muscles during training (and to your brain!). You also have an elevated heartrate, increased muscle tone and more – just as though you were experiencing the ‘fight or flight’ response.

But as Tim Ferriss would say, there is no such thing as a ‘biological free ticket’. There are many side effects associated with Clenbuterol, so let’s look at what those are and how you can mitigate them with the right PCT.

What are the Side Effects of Clenbuterol?

The first side effect of Clenbuterol is that it will make you feel nervous and jittery. You might struggle sleeping and you may feel as though your heart is about to break out of your chest. This is owing to the stimulant properties of Clenbuterol. In fact, it may cause panic attacks! As a beta agonist, Clenbuterol is actually the opposite of the popular anti-depressants/anxiolytics known as beta blockers. So it can make you feel a little strange to say the very least.

This also makes Clenbuterol addictive, just like anything that messes with brain chemistry.

What’s more, is Clenbuterol is a very serious risk to your heart health. When you increase the number of stimulants in your system and the amount of red blood cells, you increase how hard your heart is working. This can lead to a heart attack and in the long run, it can cause your heart to swell to unnatural sizes – which also increases heart attack risk.

Clenbuterol is liver toxic. That means it can be very damaging to the liver when it passes through and this can also be fatal in some cases – especially when you use the oral form. Clenbuterol is painful when injected though and may lead to serious scars.

Then there is ‘Skeletor face’.


A PCT is a ‘post cycle therapy’, which is typically a term associated with anabolic steroids. PCTs are used in this context to reset the body and to prevent long term side effects of those drugs.

Because Clenbuterol is not a steroid, it doesn’t typically involve a PCT. That said though, using the right adaptogenic herbs can help to ease many of the side effects associate with the drug.

Clenbutrol from Crazy Bulk does exactly that, but goes one step further by serving as a healthy and safe alternative to the drug too. Clenbutrol is a massive hit and has been getting incredibly positive user reviews. It is 100% legal and does not even require a prescription.
