- TB-500 (Thymosin Beta-4)
- VEGF-A, ANGPT2, MMP-2, MMP-9, IL-10
- Actin sequestration → MKL1-SRF activation
- 30–90 min (MKL1 translocation)
- 6–24 hours (mRNA), 48–72 hours (protein)
- Gold standard for angiogenic gene upregulation. Direct transcriptional mechanism, not receptor-mediated
- BPC-157
- VEGFR2, FAK, eNOS (via signaling, not transcription)
- Growth factor receptor modulation (indirect)
- 1–3 hours (receptor phosphorylation)
- 12–48 hours (signaling cascades)
- Primarily a signaling modulator. Doesn't directly alter gene transcription like TB-500
- GHK-Cu
- TGF-beta1, decorin, metallothioneins
- Copper-dependent transcription factor activation
- 2–6 hours
- 24–72 hours (collagen synthesis)
- Focused on extracellular matrix genes. Less angiogenic than TB-500
- Epitalon
- Telomerase reverse transcriptase (TERT), melatonin pathway genes
- Pineal gland regulation, telomere maintenance
- 6–12 hours
- 48–96 hours (circadian effects)
- Unrelated mechanism. Longevity and circadian focus, not tissue repair
