Preclinical with limited human data
BPC-157
BPC-157 is a synthetic pentadecapeptide that appears in the research literature as a fragment associated with a gastric protein preparation known as body protection compound. It is discussed mainly in preclinical studies, and it should be described as an experimental research peptide rather than an established therapy.
Early clinical
Kisspeptin
Kisspeptin is a peptide signaling system that plays a central role in reproductive neuroendocrinology through signaling at the KISS1R (GPR54) receptor. Human genetics and physiology studies support its importance in hypothalamic-pituitary-gonadal axis regulation.
Clinically studied
Semaglutide
Semaglutide is a synthetic peptide analog of glucagon-like peptide-1 (GLP-1) designed to activate the GLP-1 receptor with a much longer half-life than native GLP-1. It is one of the better-characterized peptide therapeutics and has substantial randomized clinical trial data in metabolic disease.
Preclinical with limited human data
Thymosin Beta-4
Thymosin beta-4 (Tbeta4) is an endogenous actin-binding peptide that has been studied in tissue repair and inflammation-related models. It appears frequently in preclinical wound and regeneration literature, while clinical evidence remains more limited.
