Product Overview
Clenbutaplex 40 mcg by Axiolabs
Clenbutaplex 40 mcg is an oral tablet containing Clenbuterol Hydrochloride, manufactured by Axiolabs and supplied as 40 mcg per tablet in 100-tablet packages.
Clenbuterol Hydrochloride Oral
Clenbutaplex 40 mcg contains clenbuterol hydrochloride, a selective β2-adrenergic receptor agonist with bronchodilator and thermogenic properties. It is approved in some countries for the treatment of bronchial asthma and chronic obstructive bronchitis, but it is not approved by the FDA for any human indication in the United States. The standard clinical oral dose in jurisdictions where it is approved is 40 mcg once daily or divided.
In bodybuilding and performance-enhancement contexts, clenbuterol is widely referenced for its fat-burning and potential anabolic effects. A 2026 randomized controlled trial in healthy adults found that 80 mcg/day of clenbuterol during resistance training significantly increased lean mass and muscle protein synthesis compared to placebo. However, clenbuterol is classified by WADA as an **S1.2 Other Anabolic Agent** and is prohibited at all times in sport. Non-medical use falls outside approved indications and carries significant cardiovascular risk.
Clenbuterol's mechanism involves β2-adrenoceptor activation, which relaxes bronchial smooth muscle and increases metabolic rate and lipolysis. Documented adverse effects include tachycardia, tremor, hypokalemia, and cardiac arrhythmias. The product's laboratory report shows a measured content of 47.89 mcg per tablet, which is 119.72% of the 40 mcg label claim.

Product Profile
Clenbuterol Hydrochloride Profile
Clenbuterol is a long-acting β2-adrenoceptor agonist with bronchodilator and thermogenic properties. Its research profile spans asthma, body composition, and anti-doping science.
β2-Adrenergic Receptor Agonist
Clenbuterol belongs to the class of selective β2-adrenoceptor agonists, which bind to and activate β2 receptors predominantly found in smooth muscle tissue including the lungs, uterus, and blood vessels. Upon binding, clenbuterol activates intracellular signaling that relaxes smooth muscle, producing bronchodilation.
The pharmacokinetic profile of clenbuterol includes rapid gastrointestinal absorption, with onset of action in 15–20 minutes and peak plasma concentrations at 2–3 hours. The bronchodilator effect persists for 6–8 hours, and the elimination half-life is approximately 35 hours. The molecular weight of clenbuterol hydrochloride is 313.65 g/mol.
At higher doses or in non-medical contexts, clenbuterol's β2-agonist activity produces metabolic effects including increased energy expenditure and fat oxidation. A 2026 randomized controlled trial in healthy adults demonstrated that 80 mcg/day of clenbuterol during 8 weeks of resistance training significantly increased lean mass and induced mTOR phosphorylation in skeletal muscle compared to placebo.
Defining Characteristic
Dual Bronchodilator and Thermogenic Activity
Clenbuterol's defining pharmacological characteristic is its dual action: β2-mediated bronchodilation for respiratory indications and dose-dependent thermogenic/anabolic effects at higher exposures.
Clenbutaplex 40 mcg vs Other Axiolabs Preparations
Axiolabs offers several compounds referenced in bodybuilding research. T3 (liothyronine) is a thyroid hormone used for metabolic acceleration. Clomiplex (clomiphene) is a selective estrogen receptor modulator for PCT. Arimiplex (anastrozole) is an aromatase inhibitor. Clenbutaplex provides β2-agonist activity for research into thermogenesis and body composition.

|---|---|---|
| Medical (approved jurisdictions) | 20–40 mcg | Once daily or divided |
| Clinical trial (resistance training) | 80 mcg | Daily |
| Non-medical (not approved) | 20–120 mcg | Titrated per protocol |
Managing Side Effects
Clenbuterol's most common adverse effects include tremor, tachycardia, palpitations, and nervousness. These effects are dose-dependent and may attenuate with continued use. More serious cardiovascular effects including arrhythmias and hypokalemia have been reported. Taurine supplementation and potassium monitoring are commonly referenced in non-medical contexts, though these practices are not supported by clinical guidelines.
Important Safety Considerations
Clenbuterol is contraindicated in patients with tachyarrhythmias, hypertrophic obstructive cardiomyopathy, and acute myocardial infarction. Caution is advised in patients with hypertension, hyperthyroidism, and diabetes. Clenbuterol can potentiate the toxicity of digoxin and may interact with β-blockers, tricyclic antidepressants, and drugs that prolong the QT interval.

Frequently Asked Questions
Clenbutaplex 40 mcg FAQ
Answers to common questions about Clenbutaplex 40 mcg, clenbuterol research, and product details.
What is Clenbutaplex 40 mg used for?
Clenbutaplex 40 mcg contains clenbuterol hydrochloride, a β2-adrenergic agonist. In jurisdictions where it is approved, it is used for bronchial asthma and chronic obstructive bronchitis. In non-medical bodybuilding contexts, it is referenced for thermogenic and potential anabolic effects, though this use is not approved.
How often should Clenbutaplex 40 mcg be taken?
The approved clinical dose is 20–40 mcg once daily or divided, with a maximum of 80 mcg/day for severe bronchospasm. Clinical research has used 80 mcg/day. Non-medical protocols reference escalation up to 120 mcg/day, but these doses are not approved and carry significant risk.
Does Clenbutaplex 40 mcg require PCT?
Clenbuterol is not an anabolic steroid and does not suppress endogenous testosterone production in the same way as AAS. Post-cycle therapy designed for steroid cycles is not applicable. Its mechanism involves β2-adrenoceptor activation, not hormonal suppression of the HPTA.
What does clenbuterol do?
Clenbuterol binds and activates β2-adrenoceptors, relaxing bronchial smooth muscle and producing bronchodilation. At higher doses, it increases energy expenditure, fat oxidation, and may enhance muscle protein synthesis.
How long does clenbuterol take to work?
Clenbuterol is rapidly absorbed after oral administration, with onset of action in 15–20 minutes and peak plasma concentrations at 2–3 hours. The bronchodilator effect persists for 6–8 hours. The elimination half-life is approximately 35 hours.
Is clenbuterol the best fat burner?
Clenbuterol has demonstrated significant effects on energy expenditure and fat oxidation in clinical research. However, it is not FDA-approved for weight loss, and its cardiovascular risks are well documented. No single fat-burning compound is universally superior.
What is the difference between Clenbutaplex and T3?
T3 (liothyronine) is a thyroid hormone that directly increases metabolic rate. Clenbutaplex (clenbuterol) works through β2-adrenoceptor activation to increase thermogenesis and lipolysis. These represent different mechanisms of metabolic acceleration.
What is the difference between Clenbutaplex and Clomiplex?
Clomiplex (clomiphene) is a selective estrogen receptor modulator used for post-cycle therapy to restore testosterone production. Clenbutaplex (clenbuterol) is a β2-agonist for thermogenic research. Their mechanisms and research applications are entirely different.
Is 40 mcg of clenbuterol a lot?
40 mcg is the standard clinical dose in jurisdictions where clenbuterol is approved for respiratory indications. The laboratory report for this Clenbutaplex product measured 47.89 mcg per tablet, which is 119.72% of the 40 mcg label claim.
