Acute poisoning symptoms are
palpitations, face and neck, limbs muscle tremors, even cannot stand, dizziness,
fatigue, people with arrhythmia are more prone to reaction, tachycardia,
ventricular extrasystole, ECG showed S-T segment depression and T wave
Patients with original sympathetic hyperfunction, such as hypertension, coronary heart disease, hyperthyroidism or taking T3,T4, these symptoms are more likely to occur.
If people take glucocorticoids at same time, it can cause hypokalemia, leading to arrhythmia.
Repeated using clenbuterol can get tolerance, reduce the effect of bronchiectasis and shorten the duration.
ALthough the toxic effects of clenbuterol were mild, but FDA study showed that people using Sympathetic stimulant drug or have allergy to clenbuterol ,will have more serious response than that of healthy individuals.
Injectable steroids are injected into muscle tissue, not into the veins. They are slowly released from the muscles into the rest of the body, and may be detectable for months after last use. Injectable steroids can be oil-based or water-based. Injectable anabolic steroids which are oil-based have longer half-life than water-based steroids. Both steroid types have much longer half-lives than oral anabolic steroids. And this is proving to be a drawback for injectables as they have high probability of being detected in drug screening since their clearance times tend to be longer than orals. Athletes resolve this problem by using injectable testosterone early in the cycle then switch to orals when approaching the end of the cycle and drug testing is imminent.
