Read the regulatory status before you compare prices.
Semax is approved and prescribed in Russia. As of October 28, 2026, Appendix B of the announced HHS section 503A policy covers Semax free base for intranasal use. HHS states that it "does not intend to take enforcement action against a State-licensed pharmacy, Federal facility, or licensed physician" when all policy conditions are met, including a patient-specific prescription and only a single Appendix A active pharmaceutical ingredient. This is interim, nonbinding enforcement discretion under a policy described as draft in the notice, not FDA approval or final placement on the 503A bulks list. Injectable Semax and modified analogues are outside this policy.

How to mix a 10 mg vial
Find the column for the amount of water you added to the vial. The number is how far to draw on a U-100 insulin syringe, where 100 units is 1 mL. This is arithmetic on the label, not a recommended dose.
