Boldaxyl 300, containing Boldenone Undecylenate, is an injectable anabolic-androgenic steroid (AAS) at 300 mg/ml in a 10 ml vial from Kalpa Pharmaceuticals. Known as Equipoise or EQ, it's used in bodybuilding for lean muscle growth, strength, and endurance enhancement, often in bulking or lean mass cycles. It has low hepatotoxicity and moderate aromatization, requiring some estrogen management.
Boldaxyl 300 enhances protein synthesis, nitrogen retention, and red blood cell production, leading to lean muscle growth, strength, and improved endurance. Its long-acting undecylenate ester ensures sustained anabolic effects, promoting quality gains with minimal water retention. Users notice steady muscle development and enhanced stamina within weeks, though mild estrogenic effects may occur.
Boldenone Undecylenate has a half-life of approximately 14-16 days, requiring weekly or bi-weekly injections. It remains detectable in the body for up to 4-5 months, depending on dosage, metabolism, and testing methods. Bloodwork and professional guidance are advised for precise clearance timelines.
Boldenone Undecylenate binds to androgen receptors (AR), promoting protein synthesis and nitrogen retention for lean muscle growth and strength. Its moderate aromatization to estrogen may cause mild water retention if not managed, while increased red blood cell production enhances oxygen delivery. The long-acting undecylenate ester ensures prolonged anabolic effects. Users notice lean gains within 2-3 weeks. What doesn't happen: no significant liver toxicity, but estrogen control may be needed.
Boldaxyl 300 excels for bodybuilders in bulking or lean mass cycles, requiring a high-protein diet and consistent training to maximize its anabolic potential.
Best for intermediate to advanced bodybuilders seeking lean muscle and endurance in bulking or lean mass cycles; suitable for men. Not recommended for beginners, women (due to virilization risk), or those with cardiovascular issues without medical clearance.

Boldaxyl 300 is typically cycled for 10-12 weeks due to its long-acting nature. A common protocol is 300-400 mg/week for men, split into 1-2 injections (e.g., 150-200 mg twice weekly). Often used in bulking or lean mass cycles, it's stacked with Testosterone Enanthate or Deca Durabolin for enhanced mass. Start PCT 14-16 days after the last injection, using tamoxifen or clomiphene for 4-6 weeks. Bloodwork guides dosing and PCT timing.
Testosterone Enanthate: Enhances muscle growth and hormonal balance.
Deca Durabolin: Supports mass and joint health.
Arimidex: Controls estrogen to prevent bloating.
Cycle Support: Supports lipid and cardiovascular health during cycles.
Boldaxyl 300 vs Deca Durabolin: Boldaxyl 300 promotes leaner gains with less water retention; Deca offers more mass with joint benefits.
Boldaxyl 300 vs Testosterone Enanthate: Boldaxyl 300 is milder with less aromatization; Enanthate provides stronger mass gains.
Boldaxyl 300 vs Trenbolone: Boldaxyl 300 is less potent but safer; Trenbolone offers greater strength and fat loss.
Review labs with a professional where lawful to ensure authenticity and safe dosing.
Start PCT 14-16 days after last injection due to long half-life; use tamoxifen (20-40 mg/day) or clomiphene (50-100 mg/day) for 4-6 weeks, possibly with HCG (500-1000 IU/week) for severe suppression. Bloodwork guides HPTA recovery, ensuring sustained gains and hormonal balance.
