Clenabol 40 (Clenbuterol HCl 40 mcg)

Clenabol 40 (Clenbuterol HCl 40 mcg) is Evolve Biolabs' mid-strength beta-2 agonist, supplied as 100 tablets in sealed blister strips. Each tablet delivers 40 mcg of clenbuterol hydrochloride, a dose that sits between the low and high ends of the common research range.

What Clenabol 40 Is

Clenbuterol is a long-acting beta-2 adrenergic agonist structurally related to salbutamol but with a substantially longer half-life. It relaxes bronchial smooth muscle, the basis of its use in respiratory medicine, and also binds beta-2 receptors in fat and skeletal muscle. That second action is why it is studied as a thermogenic and nutrient-partitioning agent. Clenabol 40 packages the hydrochloride salt at 40 mcg per tablet, with 100 tablets per box.

The History of Clenbuterol

Clenbuterol was developed in the 1960s and 1970s by Boehringer Ingelheim and marketed in Europe as Spiropent for asthma and obstructive airway disease. It was never approved for human use in the United States. In the 1980s, livestock research showed that it increased lean mass and reduced fat deposition, and those findings drove interest in its metabolic effects. It is now banned in sport and controlled in many countries.

How It Works

Clenbuterol binds beta-2 receptors on bronchial smooth muscle, causing bronchodilation, and on adipocytes, where it stimulates lipolysis. In skeletal muscle, beta-2 signalling can favour protein synthesis and limit breakdown. The drug is metabolised in the liver and has a half-life of roughly 30 to 40 hours, so repeated doses accumulate. Sustained exposure also downregulates beta-2 receptors, which is why tachyphylaxis is a recurring theme in the literature.

What the Research Shows

• Clinical studies examined clenbuterol as a bronchodilator in asthma and chronic airway disease.
• Livestock research in the 1980s reported increased lean mass and reduced fat.
• Beta-2 effects on lipolysis and protein turnover are well characterised.
• Cardiovascular stimulation and receptor downregulation are documented in human and animal work.

Research Context

Clenbuterol's long half-life changes how it behaves in research. Repeated administration produces accumulation and receptor desensitisation, so studies often focus on tachyphylaxis rather than stable effects. Residue concerns in livestock led to bans and to sensitive detection methods for urine and hair, which are now used in both food-safety and anti-doping testing. Those analytical and regulatory strands are as important as the pharmacology itself.

Strength, Pack and Authentication

Each tablet contains 40 mcg of clenbuterol hydrochloride, with 100 tablets per pack. The tablets are sealed in moisture-resistant blister strips inside a printed, tamper-evident carton stating the compound, strength and tablet count. A verification code on the packaging links the pack to Evolve Biolabs' records, and the 40 mcg unit gives a precise mid-range dose for research.
