These peptides offer a broad spectrum of regenerative and protective clinical applications.GHK-CU is widely used to stimulate collagen and elastin production, promote angiogenesis, and reduce inflammatory cytokines. Beyond aesthetics, it is researched for its ability to accelerate the healing of skin, bone, and nerve tissues. PT-141 works neurologically to enhance libido and sexual arousal. It is FDA-approved for the treatment of generalized hypoactive sexual desire disorder (HSDD) and is utilized clinically for various forms of sexual dysfunction where traditional phosphodiesterase-5 (PDE5) inhibitors may be insufficient.
As the only human antimicrobial peptide (AMP), LL-37 is a critical component of the innate immune system. Its primary clinical benefit is its broad-spectrum activity against bacteria, fungi, and viruses by disrupting microbial membranes. Furthermore, it plays a sophisticated role in wound healing by promoting the migration of immune cells and epithelial cells. It is currently being explored for its potential in treating chronic infections, biofilm disruption, and accelerating the closure of difficult-to-treat wounds, including those associated with genito-urinary prosthetics.
