Cardiogen effects

  • Reported improvement in myocardial contractility (Russian observational)
  • Possible reduction in age-related cardiac decline
  • Improved exercise tolerance in elderly CAD patients
  • Modulation of cardiac remodeling processes
  • Anti-inflammatory effects in cardiac tissue

Testagen effects

  • Reported support of Leydig cell testosterone production
  • Possible improvement in sperm parameters
  • Support of overall reproductive function
  • Anti-inflammatory effects in testicular tissue
  • Modulation of testicular gene expression

Cardiogen side effects

  • Generally well-tolerated in Russian clinical use
  • Mild injection-site reactions
  • Limited Western safety validation
  • Should not substitute for proven cardiac therapies

Testagen side effects

  • Generally well-tolerated in Russian clinical use
  • Mild injection-site reactions
  • Limited Western safety validation
  • Should not substitute for proper hypogonadism evaluation
