Averbol by British Dragon

Product Profile: Averbol (Boldenone Undecylenate) by British Dragon

Averbol is the trade name for Boldenone Undecylenate, an injectable anabolic-androgenic steroid originally developed for veterinary use. Produced by British Dragon, it is widely recognized for its slow-acting, long-lasting effects.

Chemical Identification

• Active Ingredient: Boldenone Undecylenate
• Chemical Name: 1,41,4-androstadiene-33-one,17β17β-ol
• Molecular Weight: 428.65 g/mol428.65 g/mol
• Structure: Boldenone is a derivative of testosterone, modified by the addition of a double bond at the 11 and 22 carbon positions. The undecylenate ester is attached to the 17β17β-hydroxyl group.

Formulation and Administration

• Standard Concentration: Typically available in 200 mg/mL200 mg/mL or 250 mg/mL250 mg/mL vials.
• Carrier: Sterile oil-based solution.
• Ester Half-Life: The undecylenate ester provides a long half-life, approximately 1414 to 1616 days, requiring less frequent injection intervals compared to shorter-ester compounds.
• Administration: Deep intramuscular injection.

Pharmacological Profile

• Anabolic-Androgenic Ratio: 100:50100:50. It maintains an anabolic effect equal to testosterone but possesses significantly lower androgenic activity.
• Mechanism: It increases nitrogen retention, protein synthesis, and significantly stimulates the release of erythropoietin (EPO) in the kidneys, which leads to increased red blood cell production.
• Aromatization: Boldenone aromatizes into 11-testosterone (dihydroboldenone) via the enzyme 5α5α-reductase, though it also converts to estradiol. Its rate of aromatization is significantly lower than testosterone (approximately 50%50% of the conversion rate of testosterone).

Clinical and Performance Characteristics

• Primary Application: Used primarily for lean mass gains and endurance enhancement due to the increase in red blood cell count.
• Slow Onset: Because of the long undecylenate ester, physical changes are gradual. Users typically do not observe peak efficacy until several weeks into a cycle.
• Appetite Stimulation: It is well-documented for its ability to significantly increase appetite, making it a popular choice for "off-season" or bulking phases.

Safety and Usage Considerations

• Hematological Risk: Chronic use can lead to dangerously high hematocrit levels, increasing blood viscosity and the potential risk of thrombosis or cardiovascular strain.
• Suppression: While less suppressive than many other compounds, it still inhibits the Hypothalamic-Pituitary-Gonadal (HPG) axis and requires appropriate hormonal recovery protocols.
• Estrogenic Side Effects: Although aromatization is mild, water retention and gynecomastia can still occur, particularly at higher dosages or in sensitive individuals.
