Comprehensive monographs on the most researched peptides — covering mechanisms, safety profiles, and regulatory status.
BPC-157 (Body Protection Compound 157) is a synthetic pentadecapeptide derived from a naturally occurring protein found in gastric juice. It has been extensively studied for its remarkable tissue-healing and cytoprotective properties.
Semaglutide is an FDA-approved GLP-1 receptor agonist used for type 2 diabetes and chronic weight management. Sold under the brand names Ozempic, Wegovy, and Rybelsus, it has become one of the most prescribed medications in the world.
GHK-Cu (copper peptide GHK) is a naturally occurring tripeptide with a high affinity for copper ions. Found in human plasma, saliva, and urine, it plays a key role in skin remodeling, wound healing, and anti-aging processes.
CJC-1295 is a synthetic analogue of growth hormone-releasing hormone (GHRH) designed for extended half-life. It stimulates the pituitary gland to release growth hormone and is often combined with ipamorelin for synergistic effects.
Thymosin Alpha-1 (Tα1) is a 28-amino acid peptide derived from the thymus gland that plays a central role in immune modulation. It enhances T-cell function and has been approved in multiple countries for treating chronic infections and as a vaccine adjuvant.
Semax is a synthetic heptapeptide derived from the ACTH(4-7) fragment of adrenocorticotropic hormone. Developed in Russia, it has been studied for neuroprotective, nootropic, and stroke-recovery applications.
Regulatory updates, clinical trial results, and peptide research highlights.
A major 2025 review in Frontiers in Nutrition synthesizes over 60 clinical studies on oral collagen peptide supplementation, finding meaningful effects on skin elasticity, joint function, and exercise recovery — particularly with the right co-supplements.
Researchers have engineered a tandem thymosin beta-4 peptide that outperforms the native molecule for corneal wound healing in preclinical studies, with implications for how next-generation regenerative peptides might be developed.
A randomized, placebo-controlled trial published in EBioMedicine demonstrates that intranasal kisspeptin-54 rapidly stimulates gonadotropin release in healthy adults and patients with hypothalamic amenorrhoea — offering the first non-invasive method to reactivate the reproductive hormone axis.
