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

Crystagen effects

  • Reported improvement in T-cell numbers and function
  • Restoration of age-related immune decline (Russian observational)
  • Support of thymic function in elderly patients
  • Anti-inflammatory effects
  • Recovery support after severe illness

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

Crystagen side effects

  • Generally well-tolerated in Russian clinical use
  • Mild injection-site reactions
  • Limited Western safety validation
  • Theoretical: caution in active autoimmune disease (immune modulation)

Cardiogen dosing ranges

Cardiogen vs Crystagen — common questions

What is the difference between Cardiogen and Crystagen?

Cardiogen: Khavinson short peptide bioregulator targeting cardiac muscle and vascular endothelium. Typical dose 1,000-5,000 mcg. Crystagen: Khavinson short peptide bioregulator targeting thymus / immune cells. Typical dose 1,000-5,000 mcg. Both fall under the Bioregulators category.

Can you stack Cardiogen and Crystagen?

Stacking Cardiogen with Crystagen is a protocol-design question best raised with a clinician — it depends on your goal, current bloodwork, and whether both peptides target overlapping mechanisms. Both peptides should be tracked independently with separate injection sites and timing. PinnyPeptide supports multi-peptide stacks with automatic injection site rotation.
