Showing 5 peptides tagged Skin / repair.

BPC-157

Emerging

A synthetic peptide fragment derived from a gastric protein, widely discussed for soft-tissue recovery. Human evidence remains limited relative to its online popularity.

TB-500

Emerging

A synthetic peptide associated with thymosin beta-4 research, commonly discussed alongside soft-tissue recovery and mobility. Often paired conversationally with BPC-157.

Recovery · Skin / repair

GHK-Cu

Limited human data

A copper-binding tripeptide studied in skin biology and remodeling. Appears in topical cosmetic research and in online discussions of recovery and tissue quality.

Skin / repair · Recovery

LL-37

Limited human data

The only human cathelicidin antimicrobial peptide, naturally released at wound margins during healing. Studied as a synthetic topical treatment for hard-to-heal chronic wounds, giving it more human RCT support than most "recovery peptide" research chemicals.

Immune support · Skin / repair

KPV

Emerging

The smallest active fragment of alpha-MSH (just three amino acids), studied almost entirely in mouse models of inflammatory bowel disease as an anti-inflammatory candidate. A clear example of a peptide with real preclinical mechanism data but essentially no human trials.

Evidence labels

  • EmergingMostly preclinical or early signals; human athletic data is thin.
  • Limited human dataSome human pharmacology or small studies; outcomes for fitness use remain limited.
  • Stronger clinical signalSupported by larger clinical trials in defined medical populations.

Same color code everywhere on STACKD: green = stronger clinical/human data, amber = limited human data or mechanism, slate = emerging/anecdotal, and oxblood = an in-house STACKD summary.
