Recovery & Tissue Repair Research Peptides
Tissue-repair research is the second-largest published peptide category after metabolic work. BPC-157 (body protective compound) and TB-500 (a thymosin beta-4 fragment) anchor the field and appear constantly in tendon, ligament, muscle, and gastrointestinal repair models — frequently together, since BPC-157 is studied primarily for angiogenesis and cytoprotection while TB-500 is studied for actin regulation and cell migration.
Alongside them: KPV, the C-terminal tripeptide of α-MSH studied in inflammation and gut-barrier models, and SS-31, a mitochondria-targeted tetrapeptide studied for cardiolipin binding and oxidative-stress resistance.

Frequently asked questions
+What is the difference between BPC-157 and TB-500?
They are studied for different mechanisms. BPC-157 is a synthetic pentadecapeptide investigated mainly for angiogenesis, growth-factor upregulation, and cytoprotection. TB-500 is a fragment of thymosin beta-4 investigated for actin sequestration and cell migration. Because the mechanisms are complementary rather than overlapping, they are commonly studied as a pair.
+Why is the BPC-157 / TB-500 blend supplied as a single kit?
Combination research is common enough that a pre-blended reference standard removes a source of preparation variance between labs. Both compounds are also available individually if a study design requires them dosed separately.
+What is KPV studied for?
KPV is the C-terminal tripeptide of alpha-melanocyte-stimulating hormone. It appears in the literature primarily in inflammation-modulation and gut-barrier-integrity models, and is frequently referenced in gut–skin axis research.
+Are these products for human use?
No. Every compound is supplied strictly as a research reference standard for in-vitro laboratory use — not for human or veterinary use.
