Wound Healing Peptides
Promotes wound closure and healing
Wound healing peptides accelerate the body's natural repair process by promoting new blood vessel formation, increasing collagen deposition, and recruiting repair cells to the injury site. BPC-157 is the most widely researched in this category, with extensive animal data showing accelerated healing of skin wounds, burns, muscle tears, tendon injuries, and even intestinal damage. TB-500 (thymosin beta-4) complements it by promoting cell migration through actin regulation.
GHK-Cu also belongs here as a wound healing peptide: it signals fibroblasts and immune cells to remodel damaged tissue and has been used in clinical wound care products. The appeal of these peptides is that they target the biological bottlenecks in healing (blood supply, cell recruitment, collagen production) rather than just managing symptoms.

Peptides (5)
BPC-157
BPC-157 (Body Protection Compound-157) is a 15-amino-acid fragment originally found in proteins from the human stomach lining. Most evidence comes from animal studies exploring wound healing, tendon repair, and gut health applications.
TB-500 (Thymosin Beta-4 Fragment)
TB-500 is a synthetic fragment of Thymosin Beta-4, a naturally occurring protein involved in tissue repair throughout the body. Research focuses on wound healing, tissue regeneration, and reducing inflammation.
LL-37 (Cathelicidin)
LL-37 is a natural human immune defense molecule (part of the cathelicidin family) that plays a key role in the body's first line of defense against infection. Research explores its antimicrobial, wound healing, and immune-regulating properties.
GHK (Tripeptide)
GHK is a naturally occurring three-amino-acid peptide found in human blood, saliva, and urine, with levels that decline with age. Separate from its copper-bound form (GHK-Cu), free GHK is being studied for its ability to influence gene activity patterns linked to tissue repair, inflammation reduction, and regeneration.
GHK-Cu (Copper Peptide)
GHK-Cu is a naturally occurring peptide-copper complex found in human blood, saliva, and urine. It is being studied primarily for wound healing, skin regeneration, and anti-aging applications, and is available in topical formulations.
