Repair and recovery peptides

This is the family of peptides that people reach for to heal faster, whether that is a cranky tendon, a gut problem, or a stubborn injury.

BPC-157 is the headliner. It is a 15-amino-acid chain based on a protective protein found in stomach acid, where its natural job is keeping the gut lining intact. Researchers got interested because it promotes angiogenesis (an-jee-oh-JEN-uh-sis), the growth of new blood vessels, which is like building new roads into an injured area so the repair crews arrive faster. Most of the strong evidence is in animals, but the community reports around tendon, joint, and gut healing are large and consistent.

TB-500 is a synthetic version of thymosin beta-4 (THY-mo-sin), a protein your body releases at wound sites. It helps cells migrate to where they are needed. People use it for more whole-body recovery, muscle and connective tissue especially. It is often stacked with BPC-157, the idea being that the two cover repair from different angles.

GHK-Cu (usually said "G-H-K copper" or "G-H-K C-U") is a copper-carrying peptide. It is best known for skin, healing, and hair. It shows up in serious skincare as well as in injections. It has the most visible cosmetic following of the three.

As always, the animal and lab data outrun the human trials here. These are promising and popular, but not proven.
