Cognitive & Mood

Russian nootropic peptide for focus, memory, and mental stamina under load. Semax is a synthetic heptapeptide derived from the 4-10 fragment of adrenocorticotropic hormone (ACTH), with an added Pro-Gly-Pro tripeptide tail for improved stability. It was first described in the late 1980s. The molecule has the sequence Met-Glu-His-Phe-Pro-Gly-Pro, a molecular weight of approximately 826.92 g/mol, and the molecular formula C38H54N12O9. It dissolves readily in water and is supplied as a lyophilized powder. The Pro-Gly-Pro tail is a structural feature designed to resist breakdown by prolyl endopeptidases, giving Semax greater stability than the native ACTH fragment. CAS: 80714-61-0.

Anxiolytic peptide that takes the edge off without sedation or dependence. Selank is a synthetic heptapeptide based on tuftsin, a naturally occurring tetrapeptide (Thr-Lys-Pro-Arg) found as a fragment of the immunoglobulin G heavy chain. First described in the late 1990s, it extends tuftsin with a Pro-Gly-Pro tripeptide tail to resist enzymatic breakdown. The compound has the molecular formula C33H57N11O9, a weight of 751.87 g/mol, and CAS number 129954-34-3. Also designated TP-7, it is supplied as a white to off-white lyophilized powder, readily soluble in water. The Pro-Gly-Pro extension resists cleavage by prolyl endopeptidases, giving Selank greater persistence than native tuftsin. This product is strictly for research purposes only.

Brain bioregulator peptide for cognition, focus, and neuroprotection. 20mg. Pinealon (EDR; Glu-Asp-Arg) is a synthetic tripeptide derived from the peptide bioregulator fraction of bovine pineal gland isolates. Preclinical studies have investigated its interaction with cell cycle regulatory gene expression, particularly genes associated with neuronal differentiation and DNA repair mechanisms. Research has examined Pinealon's effects on chromatin remodeling and its ability to penetrate the blood-brain barrier in rodent models. It has been used in cell culture studies exploring neuroprotective gene expression profiles. Supplied as a lyophilized powder for in vitro and ex vivo research use only.

Delta sleep-inducing peptide (DSIP) is a naturally occurring nonapeptide — a chain of nine amino acids — with the sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu. It has a molecular weight of 848.81 g/mol and the formula C35H48N10O15 (CAS 62568-57-4). First isolated in 1977 from rabbit cerebral venous blood, DSIP is classified as amphiphilic, meaning it contains both water-attracting and water-repelling regions. The tryptophan residue at its N-terminus provides a characteristic UV absorbance signature used for laboratory identification. DSIP is a low-molecular-weight amphiphilic nonapeptide — the selective membrane that separates circulating blood from brain tissue. It appears as a white lyophilized powder that is soluble in water.
