KLOW is the GLOW blend (BPC-157, TB-500, GHK-Cu) with KPV added to the vial. KPV is an alpha-MSH C-terminal fragment that signals through MC1R and MC3R, which stretches the blend's anti-inflammatory reach into gut, joint and skin models. It is the blend researchers reach for in IBD, Crohn's and colitis work.
- Four peptides in one vial: GHK-Cu, BPC-157, TB-500 and KPV, the GLOW base with KPV layered on.Complete Peptide Guide
- KPV adds MC1R and MC3R anti-inflammatory signaling across gut, joints and skin, coverage GLOW alone does not have.Complete Peptide Guide
- Positioned as the go-to blend for IBD, Crohn's, colitis, joint inflammation and post-surgical recovery models.Community protocols
- BPC-157, TB-500 and KPV were each recommended for the 503A bulks list by PCAC in July 2026 on 8-6 votes, advisory and non-binding.Complete Peptide Guide (warnings)
- Honest gap: no human RCT has tested the four-compound combination, and KPV's gut use is community-standard rather than trial-backed.Complete Peptide Guide
