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

Injectable peptides (BPC-157, TB-500) create stronger signaling effects and targeted delivery

Barrier Function The stratum corneum the outermost skin barrier benefits from copper peptide-induced improvements in lipid synthesis

It's a hormone produced in your gut after you eat, and it plays three critical roles in how your body processes a meal (Muller et al., Molecular Metabolism, 2019): It tells your brain you're full
