BPC-157, or Body Protection Compound-157, is a synthetic pentadecapeptide consisting of fifteen amino acids derived from a protective protein found naturally in human gastric juice. It has gained significant attention in preclinical research for its influence on nitric oxide systems, growth factor signalling, and vascular formation. Studies in laboratory models suggest BPC-157 may support tissue integrity across muscle, tendon, and gastrointestinal systems while modulating inflammatory responses. Its remarkable stability in biological environments and rapid systemic distribution distinguish it from many other research peptides, making it a cornerstone compound in modern regenerative and cytoprotective research.

TB-500 is a synthetic peptide derived from Thymosin Beta-4, a naturally occurring protein involved in cell structure, migration, and tissue repair throughout the body. Its primary mechanism centres on regulating actin, a key protein responsible for cellular movement and structural organisation. Preclinical research has demonstrated its potential role in promoting new blood vessel formation, reducing fibrosis, and supporting recovery in cardiac, muscular, and dermal injury models. TB-500 is widely studied alongside other regenerative peptides for its complementary signalling pathways, particularly in contexts involving inflammation, delayed healing, and age-related tissue degradation.

AHK-Cu, also known as Copper Tripeptide-3, is a synthetic copper peptide composed of alanine, histidine, and lysine complexed with a copper ion. Developed as an analogue of GHK-Cu, it was specifically engineered to target hair follicle signalling and scalp health. Research indicates AHK-Cu boosts fibroblast activity and vascular endothelial growth factor production while reducing the negative effects of oxidative stress on dermal papilla cells. Its focused mechanism on follicle biology makes it a preferred compound in hair density and scalp regeneration studies, complementing the broader skin repair applications associated with its well-known counterpart GHK-Cu.
