Synthetic pentadecapeptide BPC-157 BPC-157 is a 15-amino-acid research peptide. Published work has mostly used isolated cells, tissues, and animal models to study vascular signaling and repair-related processes. Preclinical-dominant evidence

Copper(II) complex of a tripeptide GHK-Cu GHK-Cu is a coordination complex formed by the tripeptide glycyl-L-histidyl-L-lysine and copper(II). Research often examines fibroblast behavior, extracellular-matrix signaling, and copper-dependent effects. Primarily cell and material-system evidence

Synthetic tuftsin-derived heptapeptide Selank Selank is a seven-amino-acid peptide derived from the tuftsin sequence. Published mechanistic work has examined GABA-receptor binding and neurotransmission-related gene expression, mostly in laboratory and animal systems. Mechanistic and animal-model evidence

Synthetic ACTH(4–10)-derived heptapeptide Semax Semax is a seven-amino-acid synthetic analog derived from the ACTH(4–10) sequence. Laboratory studies have examined neurotrophin-related gene expression and signaling in rodent tissues and models. Mechanistic and animal-model evidence

Thymosin-β4 fragment research peptide TB-500 TB-500 is used in current FDA materials for the N-acetylated seven-amino-acid sequence LKKTETQ, a fragment corresponding to residues 17–23 of full-length thymosin β4. Identity-sensitive preclinical evidence

Acylated dual GIP/GLP-1 receptor agonist peptide Tirzepatide Tirzepatide is an acylated peptide that activates the GIP and GLP-1 receptors. It is also the active ingredient in FDA-approved prescription products, but that fact does not make a separate research material an approved drug or a substitute for one.
