Undecanoate 250 mg

Dragon Pharma Undecanoate

Testosterone Undecanoate 250 mg is the definitive choice for athletes and individuals seeking the longest-acting, most stable form of injectable testosterone available. This product features testosterone attached to the Undecanoate ester, which boasts an exceptionally long half-life of approximately 16.5 days—more than double that of Testosterone Enanthate or Cypionate. With a concentration of 250 mg/mL in a smooth MCT oil base, this formulation is engineered to provide remarkably steady blood levels with the least frequent injection schedule of any testosterone ester. A single injection can maintain elevated testosterone levels for up to three weeks, making it the ideal foundation for long-term testosterone replacement therapy (TRT), extended cycling, or for bodybuilders who wish to minimize their injection frequency without compromising hormonal stability.

Manufactured under strict pharmaceutical standards in Dragon Pharma's European facilities, Testosterone Undecanoate offers a unique pharmacokinetic profile. The long ester chain slows the release of testosterone into the bloodstream, creating a gentle, sustained rise to peak levels over 7-10 days followed by a very gradual decline. This eliminates the sharp peaks and troughs associated with shorter esters, potentially leading to fewer estrogen-related side effects like mood swings, water retention, and acne for many users. While it takes longer to reach full saturation (up to 8-10 weeks), the resulting stability is unparalleled. It is perfect for those who travel, have busy schedules, or simply prefer not to pin multiple times per week. Whether used for legitimate TRT under medical guidance or as the backbone of a long, steady anabolic cycle, Dragon Pharma Undecanoate 250 delivers consistent, reliable results.

Key Benefits:

• Ultra-Long Half-Life (~16.5 Days): Provides the most stable testosterone blood levels available, minimizing hormonal fluctuations and potentially reducing associated side effects.
• Minimal Injection Frequency: Effective dosing can be achieved with injections just once every 7-14 days (or even longer for TRT), reducing injection site trauma and improving lifestyle convenience.
• Superior Stability for Long Cycles & TRT: The gradual release profile is ideal for cycles lasting 14+ weeks or for long-term therapeutic use, providing a consistent anabolic environment.
• Smooth Estrogen Management: Steady hormone levels often lead to more predictable and manageable estrogen conversion, making it easier to dial in your Aromatase Inhibitor (AI) dosage.
• Ideal for Stacking with Long-Acting Compounds: Pairs perfectly with other long-ester steroids like Deca 300 (Nandrolone Decanoate) or EQ 500 (Boldenone Undecanoate) for synergistic, low-maintenance cycles.

Each 10 mL vial contains 2500 mg of pharmaceutical-grade Testosterone Undecanoate, manufactured under strict quality control standards in Dragon Pharma's certified facilities for unparalleled reliability.

Usage Guidelines

Important: Testosterone Undecanoate's long half-life requires different planning. It takes 8-10 weeks to reach true "steady-state" blood levels. Injections can be administered once every 7-14 days for stability. For bodybuilding doses, splitting the dose into weekly injections is common to manage estrogen better. Always consult a healthcare professional.

• Beginner Cycle / TRT (Therapeutic): 250-500 mg injected every 14 days, OR 125-250 mg injected weekly. This range mimics clinical TRT protocols and is a gentle introduction. Start low to assess estrogen response. Have an AI like Arimidex on hand.
• Intermediate Cycle (Lean Mass/Recomp): 500-750 mg per week (injected as one dose every 7 days or split into two) for 14-16 weeks. Stack with other long esters like EQ 300 for enhanced vascularity and appetite, or with Masteron 200 for a harder look with less bloat.
• Advanced Cycle (Mass Building): 750-1000 mg per week for 16-20 weeks. Due to the long ester, front-loading (double the first 1-2 doses) is common to reach stable levels faster. Can be stacked with powerful mass agents like Trenbolone 200 (Enanthate) or Deca 500 for extreme gains. Prolactin management with Caber may be needed in such stacks.

Post Cycle Therapy (PCT):

PCT timing is CRITICAL with Undecanoate. Due to the 16.5-day half-life, you must wait 5-6 weeks after your last injection before starting PCT. Starting too early will result in exogenous testosterone still being active, making PCT ineffective. A strong PCT using Clomid and Nolvadex for 6-8 weeks is necessary. Using HCG 5000 IU during the final 4-5 weeks of the cycle (before the long wait) is highly recommended to prevent testicular atrophy.

Support & Ancillaries:

Estrogen management remains important. Due to stable levels, AI dosing can be more consistent. Monitor for high estrogen signs as levels accumulate over weeks. For those prone to hair loss, Finasteride can be used (as Test Undecanoate converts to DHT). Support cardiovascular health with a clean diet and cardio, as long-term high-dose use can impact lipids. Consider liver support if stacking with oral steroids.

Storage Instructions

Store in a cool, dry place away from direct sunlight. Ideal storage temperature is between 15°C and 25°C (59°F - 77°F). Do not freeze. Keep the vial upright. The MCT oil solution is typically smooth, but the high concentration of the long ester may make it slightly more viscous than shorter ester testosterones. Warming the vial gently in your hands or under warm water for a minute before drawing can make administration easier. Always use aseptic technique with sterile, single-use needles. Keep out of reach of children and pets.
