B7-33 is an experimental peptide based on the hormone relaxin, designed to reduce scarring and fibrosis. All the evidence so far is in animals and the laboratory. It is not a licensed medicine in the UK.
BPC-157 is a synthetic peptide made of 15 amino acids, based on a sequence found in a protein in human gastric juice. Since the early 1990s it has been studied, mostly in animals, for its effects on the healing of tissue such as tendon, muscle and the gut lining.
This is a blended product combining the two repair peptides BPC-157 and TB-500. Both are studied mainly in animals for tissue healing. Neither is a licensed medicine in the UK, and both are prohibited in sport.
Glow is a marketed name for a blend, typically combining the copper peptide GHK-Cu with the repair peptides BPC-157 and TB-500, aimed at skin and recovery. None is a licensed medicine in the UK, and the repair peptides are prohibited in sport.
KLOW is a marketed name for a blend, typically combining KPV, GHK-Cu, BPC-157 and TB-500, aimed at skin, gut and recovery. None is a licensed medicine in the UK, and the repair peptides are prohibited in sport.
KPV is a small peptide of three amino acids, taken from the tail end of a natural hormone involved in calming inflammation. It is studied mainly for inflammatory conditions of the gut. The evidence is early, and it is not a licensed medicine in the UK.
Ac-KPV-NH2 is a chemically protected form of KPV, a small anti inflammatory peptide from the hormone alpha-MSH. The protection is meant to make it more stable. Like KPV, the evidence is early and it has no UK marketing authorisation.
Pentadecapeptide is another name for BPC-157, a synthetic peptide of 15 amino acids studied mainly in animals for tissue repair. The name simply refers to its length. It has no UK marketing authorisation, and it is prohibited in sport.
A synthetic peptide related to thymosin beta-4, studied mainly in animals for tissue repair. It has no UK marketing authorisation and is not a licensed medicine here.
TB-500 Fragment 17-23 is a short piece of the TB-500 peptide, thought to carry the part linked to tissue repair. Like TB-500, it is studied mainly in animals and has no UK marketing authorisation. It is prohibited in sport.
Tri-Heal is a marketed name for a healing blend, typically combining BPC-157, TB-500 and the copper peptide GHK-Cu. None is a licensed medicine in the UK, and the repair peptides are prohibited in sport.
