Andropen 450 by British Dragon is a powerful 5-ester testosterone blend that delivers 450 mg/mL in a 10 mL vial. Formulated for advanced users, this supertest mix provides a rapid and sustained release of testosterone into the bloodstream. Each mL contains:
This multi-ester formulation mimics the concept of Sustanon, but at a significantly higher potency, making it ideal for size, strength, and serious hormone optimization.
The blend of fast and long esters ensures both immediate action and sustained hormonal levels. Testosterone is essential for muscle growth, strength, libido, and energy levels. With esters ranging from fast-acting (Acetate, Propionate) to long-lasting (Decanoate, Cypionate), Andropen 450 provides consistent anabolic support with reduced injection frequency.
According to the NIH's comprehensive review on testosterone therapy, exogenous testosterone has been clinically proven to enhance muscle mass, bone density, and recovery across a wide range of users.
For optimal results, most users inject Andropen 450 at 450–900 mg per week, typically divided into 2 injections (e.g., Monday/Thursday). Because of its high concentration and long esters, injection frequency can be lower than shorter-acting compounds.
Beginners may find the 450 mg/week dose more than sufficient, while experienced users may scale up depending on cycle structure and goals.
Andropen 450 stacks well with both oral and injectable steroids for bulking or strength-based cycles. Popular stacks include:
All testosterone esters aromatize into estrogen, which can cause side effects such as water retention, gynecomastia, and mood swings. To mitigate this, consider using an AI like Exemestane or Arimidex during cycle support, especially at higher doses.
Due to the suppressive nature of Andropen 450, a solid post-cycle therapy (PCT) is mandatory. Begin PCT approximately 18–21 days after your last injection. Recommended PCT compounds:
Ready to elevate your testosterone cycle with a high-dose blend? This British Dragon Supertest formula ships domestically across the USA, ensuring fast delivery and discreet packaging without customs risk.
This product is best suited for intermediate to advanced users who have prior experience with injectable testosterone. Due to its potency, it's not recommended for beginners or those sensitive to estrogen-related side effects without proper cycle planning and PCT support.
Andropen 450 has the same ester variety as Sustanon 250 but delivers nearly twice the total testosterone per mL, making it significantly stronger and longer-lasting.
Most users inject it twice per week to keep hormone levels stable, despite its long-acting esters allowing for once-weekly dosing in some cases.
Yes, due to aromatization. Using an aromatase inhibitor (AI) like Aromasin can help control estrogen and reduce water retention.
It's better suited for bulking or strength cycles. However, advanced users may use it in cutting with the right estrogen management and stack.
