Cognitive Research Catalog
Neuropeptides studied for neuropeptide signaling, memory and attention research, including Semax, Selank, DSIP and oxytocin.
This group collects peptides whose published research concerns neuropeptide and neurotrophic signaling. Several are offered as both a lyophilized vial and a prepared nasal spray; those are different preparations at different concentrations, and the spray format does not imply a route of administration for people or animals. Compare the listed concentration before ordering.
Semax and Selank are the two most closely compared entries here, and they are not variants of each other — Semax derives from the ACTH(4-10) fragment and Selank from the immunomodulatory tetrapeptide tuftsin, so they reach partly overlapping endpoints from different parent molecules. Each is stocked twice: as a 10mg lyophilized vial and as a prepared 10mg/5ml spray. Those are different preparations, and the spray format describes packaging rather than a route of administration. DSIP and oxytocin sit apart from both — DSIP as a broadly acting neuromodulator whose effects depend on baseline state, oxytocin as a standard reference agonist at its own receptor. Confirm concentration and storage on each page.
Every listing here is refrigerated, and all but oxytocin additionally record protection from light — but what refrigeration is protecting differs by preparation. The lyophilized vials — Semax, Selank, DSIP and oxytocin — are dry until reconstituted, and a dried peptide's clock effectively starts when it goes into solution. The two prepared sprays are already in solution at a stated concentration, so their clock started at manufacture; storage protects material that is already dissolved rather than material waiting to be. That is the substantive difference between a vial and a spray of the same compound, and it is why the two are listed separately rather than as sizes of one another. Ask for the batch documentation covering the preparation you intend to order.

Cognitive Research Catalog questions
- What is listed under Cognitive?
Six listings: DSIP, Oxytocin 2 mg, Selank 10mg, SELANK Nasal spray-10mg/5ml, Semax 10mg and SEMAX Nasal spray-10mg/5ml. Each is grouped here by the research area its published literature addresses, not by any effect. Open a listing to read its description, the sizes offered and the specifications recorded for it.
- How are the listings under Cognitive stored?
This category spans three storage requirements, so they are not interchangeable on handling: DSIP, Selank 10mg and Semax 10mg — refrigerate at 2-8°C, protect from light; Oxytocin 2 mg — refrigerate at 2-8°C; SELANK Nasal spray-10mg/5ml and SEMAX Nasal spray-10mg/5ml — refrigerate, protect from light. Each product page carries its own storage line, and that is the one that governs. How stable is a lyophilised peptide in storage? covers what temperature and residual moisture do to dried material.
- Which listings under Cognitive need reconstitution?
DSIP, Oxytocin 2 mg, Selank 10mg and Semax 10mg are supplied as lyophilized powder and require a diluent; SELANK Nasal spray-10mg/5ml and SEMAX Nasal spray-10mg/5ml ship already in solution. Bacteriostatic water is stocked separately in 3mL and 10mL vials. Savage Labs does not specify a reconstitution volume, a working concentration, or a basis for calculating either — those are determined by the protocol the material is used in, not by this catalog.
- Why does Cognitive list more than one preparation?
Because the preparation is part of what is being compared. This category carries lyophilized powder: DSIP, Oxytocin 2 mg, Selank 10mg and Semax 10mg; prepared solution (spray bottle): SELANK Nasal spray-10mg/5ml and SEMAX Nasal spray-10mg/5ml. A prepared solution and a lyophilized vial of the same compound are not the same material at a different price: one arrives at a concentration fixed at manufacture, the other is dried and its concentration is set by whoever reconstitutes it. Packaging format describes the container and establishes nothing about a route of administration.
- What purity is reported across Cognitive?
Reported purity differs by listing: 99% for DSIP; 99%+ for Oxytocin 2 mg, Selank 10mg and Semax 10mg; 99.5% for SELANK Nasal spray-10mg/5ml; 99.65% for SEMAX Nasal spray-10mg/5ml. Each figure is what was reported for that batch. A purity figure is a chromatographic measurement and does not on its own establish identity or how much peptide a vial holds — purity, identity and content are three separate measurements. Ask for the batch documentation covering the material you intend to order.
