Clenbuterol can also have negative effects on the heart, such as heart palpitations, atrial fibrillation or an irregular and often fast heartbeat, and problems with blood pressure. Increased heart rate and dilation caused by the drug can lead to what is known as cardiac hypertrophy.
Some of the most common side effects include:
Clenbuterol is well-known to cause symptoms such as rapid heart rate (tachycardia), palpitations, tremors, anxiety, lowered blood potassium (hypokalemia), and elevated blood sugar (hyperglycemia). Adverse effects happen more often with the large doses used for performance enhancement and weight loss.
Clenbuterol was well tolerated and led to a significant increase in both lean mass and the lean/fat ratio. Maximal strength increased significantly with both clenbuterol (27%) and placebo (14%); however, endurance and exercise duration decreased after clenbuterol.
The reported symptoms occur around 0.5-3 hours after the ingestion of clenbuterol containing liver and meat residues. The symptoms, which included increased heart rate, nervousness, headache, muscular tremor, dizziness, nausea, vomiting, fever, and chills, typically resolved within 2 to 6 days.
These results suggest that long-term clenbuterol treatment has a positive effect on muscle growth and force generation, but has adverse side effects such as increased muscle fatigability and development of deformities.
Conclusion: it is concluded that Clenbuterol using as weight loose do not affect in a good way on body because it raised the level of liver enzyme which means there was over loading on it. In addition to that, it increased the TG in blood stream which is harmful to human and health in general.
Clenbuterol also reduced diastolic blood pressure (P < . 01) and increased heart rate (P < . 001). The increase in heart rate was not due to direct stimulation of cardiac beta 1-adrenoceptors by clenbuterol but was consistent with a reflex response to beta 2-adrenoceptor-mediated hypotension.
Your body will need some time to adapt with effects of this drug, so it's better to start with a smaller dosage and later increase it gradually throughout the cycle. To enjoy the best results from Clenbuterol, it is advised to take it in the morning or afternoon if you have plans of working out later that day.
All patients complained of side effects, especially tremor, agitation and restlessness. The sleep EEG showed no consistent effects on sleep parameters, including REM latency and percentage of REM sleep. Thus, the impact of clenbuterol on sleep clearly differs from that of most classical antidepressants.
Clenbuterol has been observed to both increase muscle mass and reduce body fat. Additionally, it remains in the body with an active effect for up to about six days after consumption (detectable traces can remain longer).
muscle cramps, increased blood pressure, increased energy [and] slight shaking," it says. It suggests eating bananas to combat cramps and advises not taking Clenbuterol after 3.30pm as it may induce insomnia, and not too close to a workout because it can affect breathing.
No consistent effects of clenbuterol supplementation on plasma thyroid hormones, growth hormone, insulin-like growth factor-I, and corticosterone levels were detected.
Lead author Jonathan Brett from the Department of Health at the Royal Prince Alfred Hospital said general practitioners needed to be aware of the harms of clenbuterol use, which are similar to those of stimulants. "People may report maybe having palpitations, feeling edgy, feeling anxious, and have high blood pressure.
