Test C (Testosterone Cypionate 250mg/mL) – Syn Pharma

Test C is a long-acting testosterone ester designed to provide stable testosterone levels over an extended period. Testosterone cypionate supports protein synthesis, nitrogen retention, red blood cell production, muscle growth, strength development, recovery, energy levels, libido, motivation, and overall physical performance. Due to its slow-release cypionate ester, blood levels remain elevated for approximately 7–10 days, allowing for less frequent injections compared to shorter testosterone esters. Test C is commonly used as a foundational testosterone compound because of its predictable release profile, consistent results, and ability to support both physique and performance goals. Typical concentration is 250mg/mL supplied in a 10mL multidose vial.
