In the widespread realm of bodybuilding supplements, prescription drugs like Cytomel T3 and Clenbuterol have a controversial reputation as they are used as illicit performance enhancers.

Correspondingly, a review of data from two poison control centers revealed that 11 of the 13 individuals who experienced adverse reactions from Clenbeutrol had been misusing it for weight loss and bodybuilding. What is even more concerning is that two of them showed evidence of heart injury. 

Similarly, a  2022 study revealed that Cytomel (LT3) could increase the risk of heart failure by 1.7-fold and the risk of stroke by 1.8-fold. This data is also backed by a case report in which a bodybuilder’s visit to the emergency department due to elevated heart rate was traced back to his unsupervised use of Cytomel (T3).

Given these potentially life-threatening risks, your safest choice is CrazyBulk’s Clenbutrol.

What Is The Difference Between Clenbuterol And Cytomel T3?

Clenbuterol is a Bronchodilator. It is preferably utilized for treating animals with respiratory tract problems. 

In comparison, Cytomel T3 is a synthetic form of thyroid hormone. It is employed to ameliorate thyroid problems in humans (in some countries).

Beyond their main uses, these substances also demonstrate the capacity to decrease weight, promote lean muscle mass accretion, and lower body fat percentage.

For this reason, bodybuilders mostly abuse them to expedite the process of achieving the desired ‘cuts’ after the bulking phase.

But do these compounds really assist bodybuilders or not? I will discuss that shortly. 

Clenbuterol – A Potent Muscle Builder And Fat Reducer 

In 1998, the FDA approved Clenbuterol for treating COPD (chronic obstructive pulmonary disease) or asthma in horses or ‘non-food’ animals.

Over time, doctors in certain European countries received permission to prescribe it for the same reason to humans as well.

However, the FDA has not approved its use in humans in the U.S. because it mimics the effect of steroids.

Moreover, Clenbuterol is characterized as a sympathomimetic agent and a Beta-2 agonist.

The first term, ‘sympathomimetic agent,’ indicates its ability to stimulate the sympathetic nervous system, which induces thermogenic fat burning, causes appetite suppression, increases metabolism, and elevates energy levels.

The second one, ‘Beta-2 agonist’, implies that Clenbuterol can impart repartitioning effects, which means it can increase lean muscle mass while decreasing body fat percentage.

This potential of Clenbuterol to enhance muscle growth is the reason why it is compared with anabolic steroids and is widely known as a ‘non-steroidal steroid.’

Clenbuterol Pros

  • Offers respiratory support
  • Imparts anabolic effects on the muscles
  • Induces fat loss
  • Reduces appetite
  • Energizes the body

Clenbuterol Cons

  • Lacks FDA approval for human use
  • Illicitly used by bodybuilders
  • Serious side effects and fatal outcomes like heart palpitations and even death
  • Included in the list of WADA and IOC banned substances.

Cytomel T3 – Potential Treatment Of Thyroid Disorders

Cytomel T3 is a synthetically produced version of the thyroid hormone ‘triiodothyronine.’

It is prescribed to hypothyroidism patients (low thyroid hormone levels) or for treating other thyroid disorders.

In this regard, a case report suggests that some bodybuilders misinterpret the potential of Cytomel T3 and use it to increase fat breakdown.

However, note that Cytomel may only cause weight reduction in hypothyroidism patients as a side effect.

In fact, WebMD warns that taking high Cytomel doses to induce weight loss may cause fatal outcomes, especially when taken with prescription diet pills.

Not just that, has provided an extensive list of T3 side effects that may require instant medical attention.

These include symptoms of thyroid toxicity that may manifest after several days of administration but include rapid pounding heartbeat, chest pain, sweating, raised body temperature, and nervousness.

Other serious side effects could be seizures, severe headaches, dizziness, vision problems, confusion, weak or shallow breathing, and even death.

Apart from that, studies show that the T3 hormone in the body regulates muscle development.

Even so, users have yet to notice appreciable outcomes with supplemental Cytomel T3 in this regard.

Cytomel Pros

  • Improves thyroid function in those with compromised thyroid health
  • Reduces fat and weight
  • Speeds up the metabolism rate
  • Increases energy levels

Cytomel Cons

  • Available upon prescription
  • Used off-label by bodybuilders
  • Lethal and concerning side effects like thyroid toxicity and even death
  • May flatten muscles
  • Expensive: a 5 mcg Cytomel has an average price of $222.64.

Cytomel is not safe to use for weight loss or body-building purposes. Also, it has no safer and legal alternative like Clenbuterol. And here at Maxhealthliving, we do not support the illicit use of prescription drugs. So, no link here, sorry. 🙁

Clenbuterol Vs. Cytomel – What Is Best For Fat Loss & Bodybuilding?

Legally speaking, neither of these two drugs is advised for bodybuilding or fat loss. 

But if you insist on having one substance declared the better, then Clenbuterol is more popular among bodybuilders for cutting the bulk they gained instead, when compared to Cytomel.

The reason is that Clenbuterol has a more potent and long-lasting fat-burning, energizing, appetite-blunting effect than Cytomel T3.

In comparison, users taking only T3 reported that it made them extremely hungry, ate away their muscle mass, and caused a reduction in strength.

On a side note, you should alternate between the clen and t3 cycle for fat loss and bodybuilding instead of using a single supplement.

The reason is that Clen has anabolic effects while T3 has catabolic effects. Hence, the combo has yielded better results in users.

Nonetheless, I won’t recommend that you use Clenbuterol because it is banned for athletes and poses many health risks. 

Don’t worry; you still have options.

You can alternatively opt for Crazy Bulk’s Clenbutrol, which has similar effectiveness but a way better safety profile.

Clenbuterol: Important Considerations

Due to its performance-enhancing properties, the World Anti-Doping Agency (WADA) and the International Olympic Committee (IOC) have designated Clenbuterol as a banned substance.

In this context, it may help you to know that your drug test results may come out positive even after six days or more from the last time you used Clen.

Therefore, if you are planning to participate in competitive sports, then please do not use Clenbuterol to avoid issues and rejection.

Additionally, keep in mind that users (like Corinna L. Olsen on Quora) have reported developing tolerance to it. Hence, you may not experience the same effectiveness if you repeat Clen cycles frequently, such as twice in a single year.

Caution: Clenbuterol Risks

Beware of Clenbuterol’s deleterious side effects that include heart palpitations, tremors, high blood sugar or heart rate, anxiety, jitters, cardiac arrest, excessive sweating, muscle cramps, sleep problems, and even death.

In this context, WebMD states that more than 80% of Clenbuterol abusers who got serious side effects had to get hospitalized. 

Also, studies suggest that it overloads the liver and may cause kidney failure.
