Boldenone Undecylenate (Boldanon) 250 mg

Boldanon (Boldenone Undecylenate) 250 mg is Utinon's long-ester boldenone injectable, supplied as a 10 ml vial at 250 mg/ml. The undecylenate ester releases over roughly two weeks, producing a slow, low-peak curve. Each vial is sealed in a printed carton with a scratch-off authenticity code.

What Boldanon 250MG Is

Boldenone is a testosterone analogue with a double bond between carbons one and two, which reduces its aromatisation rate and changes its metabolic profile. The undecylenate ester is long and highly lipophilic, so it leaves the injection site slowly. A 10 ml vial at 250 mg/ml contains 2,500 mg of boldenone undecylenate.

The History of Equipoise

Boldenone was first synthesised in the 1940s and later marketed for veterinary use, most famously as Equipoise for horses. Its long undecylenate ester made it suitable for infrequent administration in animals, and that same property brought it into physique research. The Equipoise name remains the most common shorthand even though the compound is the same.

How It Works

After intramuscular injection, esterases hydrolyse the undecylenate ester gradually, releasing free boldenone over about two weeks. Boldenone binds the androgen receptor and aromatises at roughly half the rate of testosterone, so oestrogenic effects are milder. It does not carry nandrolone's progestogenic activity. Hepatic metabolism and urinary excretion clear the compound, and the long ester produces a correspondingly long detection window.

What the Research Shows

• Boldenone has been studied mainly in veterinary and agricultural settings.
• Its aromatisation rate is lower than testosterone but not zero.
• Undecylenate esters produce slow, prolonged release from the depot.
• Metabolite detection in urine is well characterised for anti-doping purposes.

Research Context

Equipoise sits between testosterone and the 19-nors in character. Research interest centres on its balance of modest aromatisation and steady exposure, which makes it a common comparator for other long-ester injectables. The undecylenate ester is the slowest in the Utinon range, so the curve is flat but the washout is long. That combination is the main practical difference from bolder, shorter-acting compounds, and it is why the line is usually studied over extended windows rather than short bursts.

Strength, Pack and Authentication

Each millilitre contains 250 mg/ml of boldenone undecylenate, giving 2,500 mg / 10 ml in the 10 ml vial. The vial is sealed with a flip-off cap and boxed in a printed carton that states the compound, strength and volume. A scratch-off security code inside the box links the pack to Utinon's manufacturing records.
