Why Injection Is Standard TB-4's 43-amino-acid chain is vulnerable to the same digestive processes that break down dietary protein: Stomach acid: Hydrochloric acid denatures the peptide's tertiary structure Proteolytic enzymes: Pepsin, trypsin, and chymotrypsin cleave TB-4 into inactive fragments Poor absorption: Even if fragments survive digestion, the intestinal barrier limits absorption of large, hydrophilic molecules First-pass metabolism: The liver further degrades any peptide fragments that reach it Subcutaneous injection bypasses all of these barriers, delivering intact TB-4 directly into the bloodstream with estimated bioavailability exceeding 95%
