Cas no 13103-34-9 (Boldenone Undecylenate)

Boldenone Undecylenate is a synthetic anabolic-androgenic steroid (AAS) derived from testosterone, modified to prolong its activity. It is characterized by the attachment of an undecylenate ester, which extends its half-life and ensures a slow, sustained release into the bloodstream. This compound exhibits moderate anabolic effects with relatively low androgenic activity, making it suitable for promoting lean muscle mass and endurance with reduced risk of pronounced androgenic side effects. Its stability and predictable pharmacokinetics allow for controlled dosing regimens. Boldenone Undecylenate is commonly utilized in veterinary medicine and, in some contexts, researched for its potential therapeutic applications in muscle-wasting conditions.

Additional information on Boldenone Undecylenate

Boldenone Undecylenate (CAS No. 13103-34-9): An Overview of Its Properties, Applications, and Recent Research

Boldenone Undecylenate (CAS No. 13103-34-9) is a synthetic anabolic steroid that has gained significant attention in the fields of veterinary medicine and scientific research. This compound is known for its potent anabolic effects and relatively low androgenic activity, making it a valuable tool in various applications, including muscle growth, tissue repair, and performance enhancement. In this article, we will delve into the chemical properties, biological activities, and recent advancements in the study of Boldenone Undecylenate.

Chemical Structure and Properties

Boldenone Undecylenate is a derivative of the naturally occurring steroid boldenone, which is structurally similar to testosterone but with a modified side chain. The addition of the undecylenate ester significantly extends the half-life of the compound, allowing for sustained release and prolonged effects. The chemical formula of Boldenone Undecylenate is C28H44O3, and its molecular weight is 428.65 g/mol. The compound is insoluble in water but highly soluble in organic solvents such as ethanol and acetone.

The physical properties of Boldenone Undecylenate include a white to off-white crystalline powder form with a melting point ranging from 155°C to 157°C. These properties make it suitable for various formulations, including injectable solutions and oral preparations.

Biological Activities and Mechanisms of Action

Boldenone Undecylenate exerts its effects primarily through binding to the androgen receptor (AR), which leads to the activation of gene transcription and protein synthesis. Unlike testosterone, which can be rapidly converted to dihydrotestosterone (DHT) via the enzyme 5α-reductase, Boldenone Undecylenate has a lower affinity for this conversion pathway, resulting in reduced androgenic side effects such as hair loss and prostate enlargement.

The anabolic properties of Boldenone Undecylenate are well-documented in both animal and human studies. It has been shown to promote nitrogen retention in muscle tissue, enhance protein synthesis, and increase red blood cell production. These effects contribute to improved muscle mass, strength, and endurance. Additionally, Boldenone Undecylenate has been found to have anti-catabolic properties, reducing muscle breakdown during periods of stress or injury.

Clinical Applications and Veterinary Use

In veterinary medicine, Boldenone Undecylenate is widely used for treating conditions such as anemia, weight loss, and poor appetite in horses and cattle. Its ability to stimulate red blood cell production makes it particularly useful in managing anemia associated with chronic diseases or nutritional deficiencies.

In human medicine, while not approved by regulatory agencies for therapeutic use due to potential side effects and ethical concerns, Boldenone Undecylenate has been studied for its potential benefits in conditions such as muscle wasting diseases (e.g., cachexia) and osteoporosis. Clinical trials have shown promising results in improving muscle mass and bone density without significant adverse effects.
