Cognitive Stack

The Cognitive Stack is a multi-vial research bundle pairing Semax, an ACTH(4-10)-derived peptide, with Selank, a tuftsin analogue, supplied as separate vials. Because the two arrive individually rather than pre-mixed, each can be reconstituted and handled independently within a laboratory workflow, while still being provided together as one consistently sourced set. Both peptides were originally developed in Russia for research purposes.

The two components are distinct peptide analogues. Semax is derived from the ACTH(4-10) fragment and is investigated in nootropic research, while Selank is an analogue of the immunomodulatory peptide tuftsin and is studied within the same nootropic-research field. Grouping a corticotropin-fragment peptide with a tuftsin analogue places two structurally different but thematically related research targets within a single supplied bundle for laboratory study.

Cognitive Stack UK is offered because Semax and Selank are commonly examined together as a nootropic-research pairing, both having been developed in Russia and frequently studied side by side. Supplying them as separate vials keeps each compound isolated for independent preparation while providing a single, consistently sourced set for comparative laboratory investigations of these two peptides rather than two unrelated purchases.

Each component in the bundle is analysed by reverse-phase HPLC and ESI mass spectrometry, and every vial is supplied with a batch-linked Certificate of Analysis. Both are provided lyophilised and should be stored sealed, protected from light, heat and moisture, with refrigeration recommended after reconstitution. They are sourced and handled in the UK. This product is sold strictly for laboratory research use only.
