Semax / Selank is a research-grade dual nootropic neuropeptide blend combining two of the most studied neuropeptides in cognitive neuroscience research. Semax (ACTH 4-7 analog) and Selank (tuftsin analog) target distinct but complementary neural signaling pathways — BDNF modulation and GABAergic neurotransmission respectively. Each component is independently synthesized and verified to ≥99% purity by third-party HPLC before co-lyophilization. Research Use Only.
This blend combines Semax, a synthetic ACTH 4-7 analog studied for BDNF pathway modulation and melanocortin receptor interactions, with Selank, a synthetic tuftsin analog studied for GABAergic neurotransmission and enkephalinase inhibition. The combination enables researchers to study complementary neuropeptide mechanisms within a single experimental substrate.
Research applications include dual-pathway neuropeptide pharmacology, comparative BDNF vs GABAergic signaling studies, cognitive neuroscience research, and nootropic peptide combination pharmacology. The blend enables researchers to study mechanistic overlap between melanocortin-mediated and tuftsin-mediated neural signaling.
Each component is independently synthesized via SPPS and analyzed by third-party HPLC before co-lyophilization. We guarantee ≥99% purity for each component individually.
