- VIP (Vasoactive Intestinal Peptide)
- cAMP-mediated smooth muscle relaxation and immune modulation
- VPAC1, VPAC2 (G-protein-coupled)
- ~2 minutes (native), 2–4 hours (analogs)
- Pulmonary hypertension, IBD, circadian rhythm disorders
- Best for vasodilation and immune downregulation. Not metabolic or anabolic effects
- GLP-1 Agonists (Semaglutide, Tirzepatide)
- Incretin mimetic. Insulin secretion, gastric emptying delay
- GLP-1 receptor
- 5–7 days (weekly dosing)
- Type 2 diabetes, obesity
- Best for metabolic regulation and appetite suppression. Minimal smooth muscle effects
- BPC-157
- Angiogenesis via VEGF upregulation, tissue repair
- Not fully characterized
- ~4 hours
- Soft tissue injury, gut healing
- Best for structural tissue repair. Does not cause vasodilation
- TB-500 (Thymosin Beta-4)
- Actin sequestration, cell migration promotion
- G-actin binding
- 24–30 hours
- Muscle recovery, wound healing
- Best for systemic repair signaling. No direct vascular effects
