Test C 250mg – Long-Acting Testosterone Cypionate for Strength & Muscle Growth
Test C 250mg, or Testosterone Cypionate, is a powerful long-acting ester of testosterone. It provides consistent hormonal levels, making it a trusted option for bulking cycles and testosterone replacement therapy (TRT). With its slow release, Test Cyp allows fewer injections while maintaining stable performance and muscle-building support.
Bodybuilders rely on Test C to promote lean muscle mass, improve strength, and increase endurance. It’s often the base of any serious cycle and stacks well with compounds like Deca 400mg, Anadrol, or Primo E. Its androgenic activity supports energy, focus, and libido, which makes it effective for athletes and fitness enthusiasts.
Test C 250mg boosts nitrogen retention, enhances protein synthesis, and stimulates red blood cell production. This leads to faster recovery, increased stamina, and a noticeable size and strength increase over several weeks. Many use it during the off-season for bulk or as hormone support in a cutting cycle.

By far the best testosterone I’ve used. Minimal estrogen sides, easy to pin, and my endurance is off the charts. 250mg per week feels perfect with this compound.
