What is in this blend
- 10 mg Semax + 10 mg Selank
Compositions vary by vendor. The price table compares whole-vial totals, not the amount of any one component.
Why people stack them
Semax and Selank are grouped because both appear in neurobehavioral research, but their reported experimental pathways are not the same. Semax literature includes neurotrophin and cognition-related work, while Selank research includes GABAergic and anxiety-related models.
The shared theme explains the vendor pairing. It does not mean the premixed 1:1 product has the same evidence as either peptide on its own, and direct combination research is limited.
What to check before you buy
- Confirm every named ingredient. PeptidePub matches blends by composition, not by the marketing name on the vial.
- Look for a lot-specific COA that identifies and measures each component.
- Separate the whole-vial total from the milligrams assigned to each component.
- Remember that price per mg in the table is calculated from the whole vial.
Handling and storage
Review the Semax and Selank guides and follow the stricter storage condition plus the vendor's lot documentation.
A premixed vial should not inherit a stability claim from either component without mixture-specific evidence.

GO DEEPER
This guide covers one compound. We wrote the book on all 45.
The Peptide Handbook takes everything we know from testing vendors for a living and turns it into five readable books: what each compound actually does, what the evidence really says, and the honest call when the answer is "skip this one." Plus the dosing tables, calendars, and trackers that make it usable.
