Description

Test 400 – Ultra-Concentrated Testosterone Blend for Maximum Muscle Growth

(Testosterone Propionate, Enanthate, Cypionate, Decanoate – 400mg/ml)

Test 400 is a high-potency injectable testosterone blend designed to rapidly boost testosterone levels and maintain elevated anabolic activity over time. Containing a powerful combination of four testosterone esters, this oil-based formula delivers both fast-acting and long-lasting results, making it an excellent choice for bodybuilders and athletes seeking serious mass and strength gains.


What is Test 400?

Test 400 is a premium multi-ester testosterone compound engineered for intramuscular (IM) use. It provides a rapid spike in testosterone levels within 24 hours of injection, followed by a sustained anabolic effect for 7–10 days. This allows for fewer injections per week while maintaining steady hormone levels — perfect for demanding bulking or performance-enhancing cycles.


Test 400 Composition

Each 1 ml of Test 400 delivers 400mg of testosterone from a synergistic mix of esters:

  • Testosterone Propionate – Fast release (short ester)

  • Testosterone Enanthate – Medium release

  • Testosterone Cypionate – Medium release

  • Testosterone Decanoate – Long release (long ester)

This blend creates a phased release profile that keeps blood testosterone levels high and stable for maximum efficiency.


Key Benefits of Test 400

✅ Extreme Muscle Growth
Promotes rapid muscle protein synthesis and nitrogen retention for lean mass gains.

✅ Enhanced Strength and Power
Improves strength, endurance, and aggression in the gym.

✅ Long-Lasting Effect
Staggered ester release keeps testosterone levels elevated up to 10 days.

✅ Fewer Injections
High concentration and long half-life allow for 1–2 injections per week.

✅ Increased Libido and Vitality
Supports androgenic activity including enhanced sex drive, mood, and energy levels.


Dosage & Administration

  • Beginner Dose: 400–600mg/week

  • Intermediate Users: 800–1,000mg/week

  • Advanced Users: Up to 1,200mg/week (under supervision)

  • Injection Frequency: 1–2x per week (e.g., Monday & Thursday)

  • Cycle Duration: 10–12 weeks

💡 Post Cycle Therapy (PCT) is essential after completing your cycle to restore natural testosterone production and preserve muscle gains.


Active Life & Detection

  • Active Life: 15–16 Days

  • Detection Time: Up to 3 months (for urine/blood drug testing)


Potential Side Effects

While Test 400 is extremely effective, it can carry side effects, especially at higher doses:

  • Estrogenic: Water retention, gynecomastia

  • Androgenic: Acne, hair thinning, oily skin

  • Suppression of natural testosterone

  • Blood pressure and cholesterol imbalances

To mitigate risks, consider on-cycle support, regular blood work, and aromatase inhibitors (AIs) as needed.


Who Should Use Test 400?

  • Intermediate to advanced users seeking serious size and strength

  • Bodybuilders running high-volume bulking cycles

  • Athletes looking for stable testosterone levels with less frequent injections

  • Those seeking a comprehensive testosterone foundation for stacked cycles


Final Thoughts

Test 400 is one of the most concentrated testosterone blends available, providing unmatched efficiency for muscle growth, strength, and endurance. With its blend of fast and long esters, it offers both immediate impact and sustained release, making it a top-tier choice for dedicated athletes.

🔥 If you’re ready to push beyond limits and take your physique to the next level, Test 400 delivers the results — in fewer injections.

✅ Order Test 400 now from verified suppliers and experience what high-grade testosterone enhancement really feels like.
