TB-500 is a synthetically produced thymosin beta 4, a protein produced by the thymus. It may induce healing properties through several mechanisms, including upregulation of actin, improved blood vessel formation (angiogenesis), and reduction of inflammation.
BPC-157 is a synthetic peptide similar to the body protection compound, a natural peptide found in the gastrointestinal tract that aids digestion and ulcer healing. Although BPC-157 is based on a naturally occurring body protection compound, its sequence does not exist in nature, so it is truly a synthetic peptide. This contrasts TB-500, which reflects the structure of natural thymosin beta 4.
TB-500 and BPC-157 share several possible mechanisms of action to improve healing and recovery. For example, BPC-157 has been studied for its potential to improve cell survival, migration, and angiogenesis. These are all core research theses of the TB-500 peptide as well. Clinical studies have suggested that both peptides have the potential to heal damaged joints, muscle, bone, and connective tissue.
TB-500 vs. BPC-157
TB-500 has been suggested to have a systemic effect, which means it may promote healing in injured tissue throughout the animal’s body regardless of administration location.
BPC-157 has been suggested to have a local healing effect. This means that damaged tissue will benefit most near the application site.
In addition, studies have suggested that BPC-157 may induce healing and protective effects on the gastrointestinal system and nervous tissue. Some studies observe that even considering its theoretically primarily local effects, it may promote recovery and protection from injury in these areas.
Other Possible Differences
Some veterinarians report that TB-500 may have more potential than BPC157 in animal muscle tissue. This is due to its growth and strength-promoting results in some research studies. Many studies contrastingly indicate that both peptides appear to host similar healing and protective effects on joint, bone, and connective tissue.
Some animal researchers hypothesize that TB-500 may host growth-promoting potential than BPC-157 if the only goal is the development of lean body mass in the animal. At the same time, other veterinarians have reported slightly better healing results from BPC-157 injuries.
Combining both peptides may provide an effective synergistic effect that provides maximum growth and healing benefits. Researchers are still investigating this potential.
