It is an advanced version of GHRH (1-29), synthetically developed with the intention of producing better pharmacokinetics, potentially increasing Growth Hormone levels and Insulin-Like Growth Factor 1 (IGF-1)
Warning signs requiring urgent evaluation include persistent vomiting that prevents fluid intake, severe upper abdominal pain (particularly if radiating to the back), signs of hypoglycemia that don't resolve with carbohydrate intake, symptoms of dehydration (decreased urination, extreme thirst, dizziness), or any other concerning reactions
16 Thus, targeting of IRS proteins for degradation with compounds such as NT157 may provide a means to interrupt IGF and insulin signaling
For context, the toxic dose is estimated at roughly 22,500 mg, compared to a typical weekly dose of about 6 mg
TB-500 is a thymosin beta-4 fragment commonly discussed for its role in cell migration, tissue repair signalling, and recovery-focused research contexts
