Cortagen effects

  • Reported support of cortical neuron function and gene expression
  • Improvements in memory and attention (Russian observational)
  • Neuroprotection in cerebral ischemia models
  • Possible support for post-stroke and post-concussive recovery
  • Modulation of neuroplasticity-related gene expression

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

Cortagen side effects

  • Generally well-tolerated in Russian clinical use
  • Mild injection-site reactions
  • Limited Western safety validation
  • Possible mild sleep disturbance with late-day dosing

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

Cortagen vs Prostamax — common questions

What is the difference between Cortagen and Prostamax?

Cortagen: Khavinson short peptide bioregulator targeting cortical neurons and CNS gene expression. 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 Cortagen and Prostamax?

Stacking Cortagen 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.

Which is dosed more frequently, Cortagen or Prostamax?

Cortagen is typically dosed: Once daily morning (SubQ) or intranasal for Cognitive support. Prostamax is typically dosed: Once daily (SubQ) or sublingual for Prostate health support.

Are Cortagen and Prostamax FDA approved?

Cortagen: Not FDA approved. Prostamax: Not FDA approved.
