Argireline (Acetyl hexapeptide-3) is a peptide composed of amino acid chains that significantly inhibits Ca2+-dependent neurotransmitter (acetylcholine) release at the neuromuscular junction, exhibiting notable anti-wrinkle and anti-aging activity[1][2][3].

Muramyl dipeptide (MDP) is a synthetic immunoreactive peptide, consisting of N-acetyl muramic acid attached to a short amino acid chain of L-Ala-D-isoGln. It indirectly decreases osteoclast differentiation by reducing the RANKL/OPG ratio and directly increases osteoblast differentiation by up-regulating Runx2 gene expression through MAPK pathways, thereby inducing bone formation via Runx2.

H-Ile-Lys-Val-Ala-Val-OH (IKVAV) is a short peptide with a sequence length of 5, present in the extracellular matrix (ECM), on the α-laminin chain. H-Ile-Lys-Val-Ala-Val-OH participates in a variety of life activities, such as promoting cell adhesion, neurite outgrowth, angiogenesis, collagenase IV production and tumor growth. H-Ile-Lys-Val-Ala-Val-OH can induce rapid differentiation of neural progenitor cells into neurons and neurite outgrowth.

Oligopeptide-41 acetate is a synthetic, short-chain bioactive peptide sequence, typically formulated as an acetate salt to enhance stability and solubility, that has been reported to possess hair growth-promoting effects by potentially stimulating follicular cells and is consequently used as a functional cosmetic ingredient in topical formulations.

TB-500 is a synthesised peptide, essentially a short-chain version of the naturally occurring Thymosin Beta-4.
