Boldebol Boldenone Undecylenate Research Compound: A Long-Acting Anabolic Steroid for Veterinary & Metabolic Studies

If your research investigates anabolic steroid pharmacology, androgen receptor signalling, or the metabolic effects of long‑acting testosterone derivatives, Boldebol Boldenone Undecylenate research compound — also known as Equipoise, Parenabol, or Ba 29038 — offers a precisely defined and extensively characterised synthetic tool. Boldenone undecylenate is a synthetic anabolic androgenic steroid (AAS) and a long‑acting ester of boldenone, which is the 1(2)-dehydrogenated analogue of testosterone.

It was originally developed as a long‑acting injectable alternative to methandrostenolone (Dianabol) for androgen deficiency disorders. While primarily used in veterinary medicine to promote muscle growth, improve appetite, and enhance the general condition of debilitated horses, boldenone undecylenate has also found applications in human research as an endogenous metabolite. This makes Boldebol Boldenone Undecylenate research compound a valuable tool for laboratories investigating androgen receptor pharmacology, anabolic signalling pathways, and the molecular mechanisms underlying muscle protein synthesis.

At Chinese Grey Peptides, we supply high‑purity Boldebol Boldenone Undecylenate research compound to research institutions and wholesale buyers across the United Kingdom, France, Germany, Spain, Sweden, Italy, and the USA. Every batch is manufactured under GMP‑compliant conditions, verified for purity, and accompanied by a Certificate of Analysis (COA), ensuring your investigations into anabolic steroid pharmacology and metabolic regulation begin with uncompromising quality.

What Is Boldebol Boldenone Undecylenate and How Does It Work?

To fully appreciate the research potential of Boldebol Boldenone Undecylenate research compound, it is essential to understand its biochemical structure, its mechanism of action as an androgen receptor agonist, and its distinct pharmacological properties.

The Long‑Acting Androgen Ester

Boldenone undecylenate is a synthetic steroid ester with the molecular formula C₃₀H₄₄O₃ and a molecular weight of approximately 452.67‑452.67 g/mol. It has a CAS number of 13103‑34‑9. The compound contains six chiral centres at carbon positions C8, C9, C10, C13, C14, and C17. The undecylenate ester is a long‑chain fatty acid that significantly prolongs the compound’s half‑life, with an estimated half‑life of approximately 14 days following intramuscular administration.

The compound is also known under the trade names Equipoise, Ganabol, Equigan, and Ultragan. It is supplied as an injectable preparation, typically formulated in oil with benzyl alcohol as a preservative.

Mechanism of Action: Androgen Receptor Agonism and Anabolic Signalling

The biological activity of Boldebol Boldenone Undecylenate research compound is mediated through its action as an agonist of the androgen receptor (AR):

• Androgen Receptor Binding: Boldenone undecylenate exerts its effects by binding to intracellular androgen receptors, which are present in various tissues throughout the body. This binding triggers a series of molecular events within the cell.

• Transcriptional Regulation: Once bound to the androgen receptor, a complex is formed that translocates to the nucleus of the cell, where it acts as a transcription factor, regulating the expression of specific genes. These genes encode for proteins responsible for the physiological effects of boldenone undecylenate.

• Increased Protein Synthesis and Muscle Growth: Boldenone undecylenate increases nitrogen retention and protein synthesis, leading to enhanced muscle growth. It also increases appetite and stimulates the release of erythropoietin in the kidneys.

• Anabolic vs. Androgenic Activity: The activity of boldenone is mainly anabolic, with a low androgenic potency. It acts similarly to methandrostenolone but with fewer adverse androgenic effects. Unlike nandrolone, boldenone lacks progesterone receptor interaction and the associated progestogenic side effects.
