  • BPC-157

    BPC-157 is a synthetic 15-residue peptide (a pentadecapeptide). Its sequence was described as a partial fragment of a protein isolated from gastric juice, and much of the literature calls it a "stable gastric pentadecapeptide".

  • GHK-Cu

    GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine (GHK). GHK binds copper with high affinity through the histidine imidazole, the glycine amino group and the backbone amide nitrogen. Its coordination chemistry was characterised in the early 1980s.

  • NAD+

    NAD+ (nicotinamide adenine dinucleotide, oxidised form) is not a peptide. It is a dinucleotide coenzyme that carries electrons in redox reactions and is consumed as a substrate by sirtuins and PARP enzymes.

  • SS-31

    SS-31 (also called elamipretide or MTP-131) is a synthetic, cell-permeable tetrapeptide, D-Arg-Dmt-Lys-Phe-NH2. It is one of the Szeto-Schiller peptides, which concentrate at the inner mitochondrial membrane.

  • Tesamorelin

    Tesamorelin (TH9507) is a synthetic analogue of growth-hormone-releasing factor (GRF). It contains the 44-amino-acid GRF sequence with a trans-3-hexenoyl group added at the N-terminus, which makes it more resistant to enzymatic breakdown.

  • PT-141

    PT-141 (bremelanotide) is a synthetic cyclic heptapeptide that agonises melanocortin receptors. It is a metabolite-related analogue of Melanotan II: the C-terminal amide is replaced with a free carboxylic acid.

  • Selank

    Selank is a synthetic heptapeptide, Thr-Lys-Pro-Arg-Pro-Gly-Pro. It is an analogue of the immunomodulatory tetrapeptide tuftsin (Thr-Lys-Pro-Arg), extended with Pro-Gly-Pro at the C-terminus for stability. It was developed at the Institute of Molecular Genetics in Moscow.
