Tissue repair is the single most researched use for peptides, and a handful of compounds come up again and again for healing and recovery. Here is an honest look at the main ones, what the evidence actually supports, and how they are used together.
Short version: The two most studied recovery peptides are BPC-157 (gut, tendon, and soft-tissue repair) and TB-500 (broad tissue repair and angiogenesis). GHK-Cu is a third, more skin-focused option. Most of the evidence is preclinical (animal) rather than human, which is important context.
BPC-157
BPC-157 is a synthetic fragment of a protein found in stomach juice. In animal studies it accelerates healing across a remarkable range of tissues: tendon, ligament, muscle, and especially the gut lining. It appears to work partly by promoting angiogenesis, the growth of new blood vessels into an injury, which is often the rate-limiting step in repair. It is unusually stable and has even been studied orally for gastrointestinal issues. Full dosing, mechanism, and evidence are on the BPC-157 reference page.
TB-500
TB-500 is a synthetic version of Thymosin Beta-4, a protein the body concentrates at injury sites. Its main action is regulating actin, which helps repair cells migrate to a wound, and like BPC-157 it promotes new blood-vessel growth. It tends to be used for broader, more systemic recovery, and notably it has a somewhat larger human trial base than most research peptides (in cardiac and corneal contexts). Details are on the TB-500 reference page.
GHK-Cu
GHK-Cu is a copper-binding tripeptide studied mostly for skin: collagen production, wound healing, and anti-inflammatory effects. It is the recovery peptide most associated with cosmetic and dermal use rather than deep soft-tissue injury. (A full profile is coming to the database.)
The classic recovery pairing
BPC-157 and TB-500 are frequently used together because their strengths are complementary: BPC-157 is often described as more localised to a specific injury, while TB-500 is more systemic. Some protocols add a growth-hormone peptide like CJC-1295 plus ipamorelin to support overall recovery capacity.

What the evidence really shows
This is the part most sources skip. The healing results for BPC-157 and TB-500 are genuinely striking, but the great majority come from rodent studies, and BPC-157 in particular relies heavily on one research group’s work. Animal data does not automatically translate to humans, independent replication is limited, and neither peptide is approved for human use. Treat the recovery claims as promising but unproven. We explain how we weigh this kind of evidence on the Research & Evidence Standards page.
Using them correctly
Both arrive as a powder and need reconstitution before use. See how to reconstitute peptides, then use the calculator to convert your dose into exact syringe units.
