GRF (1-29) amide (rat) is a synthetic peptide which can stimulate the growth hormone (GH) secretion.

Isotocin ((Ser4,Ile8)-Oxytocin) is a polypeptide that can be found by peptide screening. Peptide screening is a research tool that pools active peptides primarily by immunoassay. Peptide screening can be used for protein interaction, functional analysis, epitope screening, especially in the field of agent research and development.

D-Kyotorphin is a synthetic neuropeptide kyotorphin analog that produces naloxone reversible analgesia.
