PGPIPN vs TB-500

Side-by-side comparison of key properties, dosing, and research.

Immune Support
PGPIPN
Recovery & Repair
TB-500
Summary
PGPIPN is a bioactive hexapeptide (Pro-Gly-Pro-Ile-Pro-Asn) derived from beta-casein during enzymatic digestion. It exhibits anti-inflammatory properties via opioid receptor modulation and cytokine suppression, making it relevant for gut health, systemic inflammation, and as a component of casein-derived functional foods.
TB-500 is a synthetic fragment of Thymosin Beta-4, a naturally occurring peptide found in nearly all human and animal cells. It promotes cell migration to injury sites, accelerates tissue regeneration, and reduces chronic inflammation.

Key Benefits
  • Anti-inflammatory effects via cytokine suppression
  • Gut mucosal protection and intestinal barrier support
  • Opioid receptor modulation for gut motility regulation
  • Potential analgesic activity via central and peripheral opioid pathways
  • Explored for inflammatory bowel conditions and gut dysbiosis
  • Natural origin (food-derived) with favorable safety profile
  • Enhances muscle tissue regeneration
  • Accelerates healing of wounds and injuries
  • Reduces inflammation and pain
  • Improves flexibility and mobility
  • Promotes new blood vessel formation
  • Supports hair growth and skin health
  • May improve cardiac function after injury
  • Systemic healing effect — works at distance from injection site
Side Effects
  • Generally very well-tolerated given food-derived origin
  • Theoretical opioid-mediated constipation at high doses
  • Rare milk protein allergy in casein-sensitive individuals
  • Injection site discomfort
  • Fatigue (rare)
  • Headache (rare)
