Healing peptide comparisons

Direct side-by-side comparisons of the most-discussed research peptides for tissue repair and regeneration.

• BPC-157 vs TB-500

  BPC-157 and TB-500 are the two most-discussed research peptides in soft-tissue repair. They have overlapping interest areas — tendon, ligament, and vascular healing — but operate by different mechanisms and rest on quite different bodies of evidence.

• GHK-Cu vs TB-500

  GHK-Cu and TB-500 are sometimes grouped together as 'tissue-repair peptides', but the two operate at very different scales — GHK-Cu primarily as a transcriptional modulator of dermal fibroblasts, TB-500 primarily as a cell-migration peptide.

• KPV vs LL-37

  KPV and LL-37 occupy overlapping but distinct niches in the inflammation–antimicrobial peptide space. KPV is small, charge-neutral, and primarily anti-inflammatory; LL-37 is larger, cationic, and combines direct antimicrobial activity with broad immunomodulation.

• BPC-157 vs AOD-9604

  Both BPC-157 and AOD-9604 are discussed in the context of post-injury recovery, but they originate from very different research programmes and target different tissues.
