From the composition point of view, Clenbuterol belongs to β₂-adrenaline receptor agonist. It binds to human receptors with its specific chemical structure, activates intracellular signaling pathways, promotes fat decomposition, dilates bronchi, and affects cardiovascular function. Medically, it was once an asthma treatment drug that can relieve dyspnea, but it has been gradually eliminated because it can cause serious cardiovascular side effects such as palpitations and arrhythmias; researchers have also tried to use it for the treatment of chronic obstructive pulmonary disease, but it is also hindered by side effects.
In the fitness and competitive sports world, Clenbuterol is regarded as a “powerful fat-reducing artifact” that can quickly accelerate fat decomposition, improve basal metabolism, and help fitness enthusiasts shape clear muscle lines in a short period of time; it can also enhance cardiopulmonary function and improve sports endurance, which has also led some athletes to take risks and use it in violation of regulations in pursuit of results.
CLENBUTEROL Product Introduction
Clenbuterol was originally developed as a veterinary drug and poultry feed additive, and was later used in the fields of medicine and fitness due to its special physiological effects. However, due to its significant side effects and risk of abuse, there have been many controversies in its use and management.
I. Basic Information
(I) Composition and Structure
The chemical name of Clenbuterol is N-[(tert-butylamino)methyl]-4-amino-3,5-dichlorobenzyl alcohol, and its chemical formula is C₁₂H₁₈Cl₂N₂O. It is a β₂-adrenaline receptor agonist. This structure enables it to specifically bind to β₂-adrenaline receptors in the body, thereby exerting a series of physiological effects.
(II) Dosage Form and Specifications
Common dosage forms include tablets, capsules and oral solutions, with various specifications. The common specifications of tablets are 20μg/tablet, and capsules and oral solutions will also have different dosage packaging according to different brands and uses. These dosage forms are convenient for users with different needs to choose, but they also increase the risk of improper use.
(III) Mechanism of action
When clenbuterol enters the human body, it binds to β₂-adrenaline receptors, activates adenylate cyclase, and increases the content of cyclic adenosine monophosphate (cAMP) in cells. As a second messenger, cAMP can regulate the activity of multiple enzymes in cells, thereby affecting fat metabolism, respiratory function, and cardiovascular system. In terms of fat metabolism, it can promote fat decomposition while inhibiting fat synthesis; in terms of respiratory function, it can relax bronchial smooth muscles and dilate airways; in the cardiovascular system, it can cause reactions such as increased heart rate and increased myocardial contractility.
II. Main application scenarios
(I) Medical use
Treatment of asthma: In the medical field, clenbuterol was initially used to treat respiratory diseases such as asthma. By dilating the bronchi, it can effectively relieve the dyspnea symptoms of asthma patients and improve ventilation function. However, due to its side effects on the cardiovascular system, such as causing palpitations and arrhythmias, it has gradually been replaced by safer and more effective drugs in the treatment of asthma.
Other potential applications: Some studies have explored its application in diseases such as chronic obstructive pulmonary disease (COPD), but its clinical promotion is also limited due to side effects.
(II) Fitness and competitive sports
Fat reduction: In the fitness and competitive sports world, Clenbuterol has attracted much attention for its powerful fat reduction effect. It can accelerate fat decomposition, increase the basal metabolic rate, and enable the body to consume more calories even at rest. Many fitness enthusiasts claim that after using Clenbuterol, with proper diet and exercise, they can significantly reduce body fat percentage in a short period of time and shape clearer muscle lines.
Improve endurance: It can also enhance cardiopulmonary function, improve exercise endurance, and enable athletes to maintain high-intensity exercise for a longer period of time during competitions. Therefore, it has been illegally used by some athletes to improve their competitive performance.
None of our HGH lines are inherently better than the other. Each batch comes with a corresponding test report. Purity and dimer can be a decent proxy for “quality”, you want purity as high as possible and dimer as low as possible. The main factor to consider in our opinion, is the price per IU. Supreme is usually the best bang for buck option. Historically, Supreme & Deluxe have shown lower dimer content, although this may not always be the case, so of course reference the corresponding test reports.
For HGH, we typically recommend 1ml for every ~10 IU in the vial. If a batch tests at an average of 290 IU per kit, that is an average of 29 IU per vial, and we’d recommend 2.9ml of bacteriostatic water. This will make the syringe math similar to a traditional 100 iu kit with 1ml of solution For peptide reconstituion, you can use our amazing Dosage Calculator.
Not necessarily. If you look through all our lab reports, particularly the ones with multiple test reports in a single batch, you will see that the intra-batch variance can actually be quite high. When you purchase a batch, you can expect some of the vials in your kit to be as much as 5-15% +/- whatever the corresponding lab test reflects. This is simply the reality of product that is not made to the same standards as pharmaceutical grade growth hormone. To state otherwise would be disingenous. There can also be a high variance in the dimer content intra-batch. (For Example: Economy B, Deluxe A, etc) Over time, we’ve increased the volume of samples analyzed for each batch, to provide more transparancy regarding the potential for intra-batch variance. If you use the average IU figure provided on each product, your dosage should average out over time, so don’t overthink your administration protocol too much. We know it can be a bit overwhelming with all the different numbers provided. That said, don’t hesitate to reach out if you need specific guidance on dosage or reconstitution.

GW-501516, also known as Cardarine, is a controversial research compound. It was originally developed to treat metabolic and cardiovascular diseases. Its unique chemical structure (6-[2-[[4-(2-methylpropyl) phenyl] methyl] phenoxy]-2-naphthoic acid, chemical formula C₂₅H₂₄O₃) enables it to bind tightly to PPARδ receptors, activate downstream signaling pathways, and change the body’s metabolic pattern.
In terms of potential efficacy, it can be called a “potential stock” in the field of sports. Animal experiments show that the exercise endurance of mice using it has been greatly improved, and the continuous exercise time on the treadmill has been extended from 160 minutes to 270 minutes. The reason is that it can prompt muscles to consume fat for energy first and delay fatigue. At the same time, it has also begun to show its edge in improving blood lipids and regulating blood sugar. It has the potential to reduce the risk of cardiovascular disease and improve insulin resistance, and even shows hope for the treatment of muscle atrophy. However, most of these are still in the stage of animal experiments and preliminary human studies.

Fluoxymesterone, as a synthetic androgen and anabolic steroid drug, has shown significant efficacy in medical treatment due to its unique molecular structure and mechanism of action. From the perspective of drug properties, its chemical structure is modified on the basis of testosterone, 17α-methylation confers good oral activity, and 9-fluorine atoms enhance androgenic and anabolic effects. Common oral tablets are available in specifications such as 2.5mg, 5mg, and 10mg, which can meet the treatment needs of different patients. After entering the human body, it binds to androgen receptors, regulates gene expression, and promotes protein synthesis. It can not only increase muscle strength and improve endurance, but also supplement androgens and treat related deficiency diseases.
In clinical applications, fluoxymesterone is an important drug for the treatment of male androgen deficiency, which can improve patients’ sexual desire, promote the development of secondary sexual characteristics, and enhance physical strength; in the treatment of advanced breast cancer, it can regulate hormone balance, inhibit the growth of cancer cells, and bring new hope to postmenopausal female patients; it can also be used to treat weight loss caused by excessive protein decomposition.
