Semax + Selank Blend

Semax + Selank Blend is a pre-mixed vial combining Semax with Selank, sold as a single research product. It is currently offered by one EU supplier (CertaPeptides) — not yet a widely stocked combination. Products are sized by the total milligram content per vial; the exact peptide-to-peptide ratio is set by the supplier.
