When to use TB-500 & BPC-157

BPC-157: Standard shelf life: 28-30 days refrigerated Maximum (if necessary): 45 days, expect 10-15% potency loss Very stable peptide due to short sequence Shows minimal degradation in first month TB-500 (Thymosin Beta-4): Standard shelf life: 28-30 days refrigerated Maximum: 45-60 days, expect 15-20% potency loss Relatively stable in solution Longer peptide chain but still maintains structure well KPV: Standard shelf life: 28-30 days refrigerated Maximum: 30-40 days Tripeptide (very short), highly stable Minimal degradation within first month Recommendation: Follow 28-30 day rule for these healing peptides
