However, they lack the complexity of whole organisms and cannot replicate crucial physiological factors such as metabolism, absorption, or systemic toxicity

These enzymes evolved to break down dietary protein, and they treat therapeutic peptides the same way First-pass metabolism: Any peptide that survives digestion and crosses the intestinal wall faces further breakdown in the liver before reaching systemic circulation Size and charge: CJC-1295 (30 amino acids) and Ipamorelin (5 amino acids) are both too large and too hydrophilic to passively cross the intestinal epithelium in meaningful amounts Subcutaneous injection bypasses all of these barriers, delivering the intact peptide directly into the bloodstream with near-100% bioavailability

Stem cell treatments run $5,000 or more with variable results
