Clearing Up Clenbuterol

A Dopers Delight or Misused Stimulant?

Following the Olympics in 1992, a new breed of stimulant gained global recognition. Hailed as the “dopers delight”, this anti-asthma medication was special. Not only could it be used as a stimulant but many believed it could also enhance muscle growth. Only 4 years earlier, steroid guru Dan Duchaine introduced the bodybuilding world to this same drug - which to this day remains one of our sports most misunderstood and misused compounds: Clenbuterol Hydrochloride.

Targeting specific receptor sites in the body’s sympathetic nervous system (SNS), Clen is a selective beta-2 sympathomimetic… wait, a what?

A car backfires and subconsciously you jump off your couch - this is an automatic physiological response initiated by our SNS in response to a perceived threat. Known as fight-or-flight, this response is the result of the release of a hormone called norepinephrine (NE). To work, NE has to bind and activate a specific receptor in your body called a beta-2 receptor. Think of this like a lock and key. Only one key (NE) can both fit (bind) and unlock (activate) one lock (beta-2 receptor).

This is where Clen comes in. Clen acts as a “fake” key that can unlock only some beta-2 receptors (why it’s called “selective”).  

Although its labeled use is an anti-asthma medication, Clen is able to unlock fat and muscle tissue cells throughout the body. Like other beta-2 agonists, clen is a “thermogenic” = Clen-sweats. This is caused by an increase in body temperature and metabolic rate, as well as its ability to directly target fat cell breakdown of triglycerides to free fatty acids is what makes Clen such as popular “fat loss” drug.

Its anabolic capabilities however are still up for debate. Although since the early 90s bros have been using clen as a part of post-cycle therapy or as an alternative to steroids to get “lean-gains”, there remains no human research (animal studies only) that provide evidence to support an increase in lean muscle mass as a result of clen. Regardless, Clen has become a stable drug for many athletes both inside and out of bodybuilding. While Clen-shreds may sound enticing, they certainly don’t come without controversy and concern. It doesn’t matter how Clen gets into your body – inhaled, pill or liquid form, or injected, remember this: Clen is dangerous.

Keep in mind that clen is different than other beta-2 agonists or stimulants based off: specificity, potency, and duration of effect. This makes for steady, strong blood levels of Clen, which often are easy to achieve with just a single or twice-daily dose (thanks to its 35-hour half-life). After a few weeks (usually 4-6 weeks) the body’s beta-2 receptors slowly stop responding due to a process called “down regulation” … simply put, they stop responding and require rest (aka. stop the drug).

However, like other performance enhancers, Clen is great at turning users into complete idiots by tempting them with magical everlasting results. What follows is the “more is better, longer is better” complex.       

From developing a psychological dependency based off ill-informed perceptions that Clen can be used long term, to the fact that users gauge the effectiveness of the drug based off the presence initial side effects such as shaky hands, insomnia, sweating and nausea – it appears that we have a growing Clenhead epidemic on our hands.  

Yes, initial side effects should dissipate after a few days and this does NOT mean that the drug has stopped working, so please stop boosting the dose to supersonic levels and somehow believe that stacking it with other stimulants will results in “better results” and not a cardiac arrest. Wake up and education yourself on drug dependency and the long term effects of Clen that happen even after beta-2 receptors stop “responding.”

Not only that, due to its strength, long half-life, and perceived effectiveness, there is such thing as Clen toxicity – which is why in Canada it’s not available for human use even with a prescription, and within veterinary practice has dramatically declined over the past few years.

Clen has never been made available for human or animal use in the US, and within sport clen it is completely banned regardless of the fact that some countries around the world (Bulgaria, Russia and China) continuing to prescribe it as a therapeutic drug. (… cough cough, the IOC wonders why there has been an increase of athletes with “asthma”).

Since the mid-90’s, it’s even illegal to use Clen to bulk-up livestock. Not only were the animals questionable, but those who ate Clen’d meat suffered symptoms of Clen overdose, such as fever, vomiting and diarrhea. Just an FYI to athletes who travel - be mindful that not all countries have banned its use in livestock. Anti-doping agencies have reported a number of cases where athletes tested positive for Clen after eating contaminated meat … or at least that’s what the athlete told officials after being caught Clen-handed.

Regardless of the fact that Clen is pretty much illegal for ALL consumption, it continues to be widely available on the black market and used for performance enhancement. From the consumption of cocaine in 18th century, amphetamine use during cold-war and now to today’s Clenheads – even though athletes have been using stimulants for centuries it doesn’t make it safe or smart.
