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

Prostamax effects

  • Reported improvement in chronic prostatitis symptoms
  • Possible reduction in BPH-related urinary symptoms
  • Anti-inflammatory effects in prostate tissue
  • Modulation of prostate gene expression
  • Russian observational support for elderly male prostate health

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)

Prostamax side effects

  • Generally well-tolerated in Russian clinical use
  • Mild injection-site reactions
  • Limited Western safety validation
  • Not a substitute for proper urological evaluation

Crystagen vs Prostamax — common questions

What is the difference between Crystagen and Prostamax?

Crystagen: Khavinson short peptide bioregulator targeting thymus / immune cells. Typical dose 1,000-5,000 mcg. Prostamax: Khavinson short peptide bioregulator targeting prostate tissue. Typical dose 1,000-5,000 mcg. Both fall under the Bioregulators category.

Can you stack Crystagen and Prostamax?

Stacking Crystagen with Prostamax 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.
