Boldenone undecylenate(Cas 13103-34-9) Usage

Description

Boldenone Undecylenate falls under the category of androgenic anabolic steroids, used primarily in veterinary medicine but also in bodybuilding and performance enhancement contexts.

Therapeutic Function

Anabolic

Uses

Boldenone Undecylenate is a synthetic anabolic-androgenic steroid (AAS) derived from testosterone. It is often referred to by its brand names like Equipoise or Parenabol. Initially designed for veterinary use, especially in horses, it was previously used in humans for muscle wasting conditions. It is administered via intramuscular injection and has a long-lasting effect due to its ester component, undecylenate, which delays its release into the bloodstream.
Chemical Structure Boldenone is structurally similar to testosterone but has a double bond between carbon atoms 1 and 2, which reduces its androgenic and estrogenic activity. It is connected to the undecylenate ester, increasing its half-life in the body.
Mechanism of Action Boldenone exerts its effects by binding to the androgen receptor in muscle tissues, which promotes protein synthesis and nitrogen retention. This increases muscle mass and reduces muscle breakdown.
Side Effects

Androgenic:
May cause masculinization symptoms such as acne, increased hair growth, and voice deepening. Women may experience virilization, including facial hair growth and voice changes.

Estrogenic:
Boldenone has some estrogenic effects, though less potent than testosterone. It may cause water retention, gynecomastia, and increased fat storage in some users.

Others:
Long-term or high-dose use may result in liver toxicity, increased blood pressure, and potential cardiovascular issues. It also has long detection times, making it problematic for athletes subject to drug testing.
