Pinealon oral vs injectable represents two distinct pharmacokinetic pathways: oral administration subjects the peptide to enzymatic degradation in the GI tract with variable absorption (bioavailability estimated at 515%), while subcutaneous injection delivers the peptide directly into interstitial tissue where absorption into capillaries occurs rapidly and predictably, with bioavailability approaching 8095%

Because of its history of safe use, few populations should avoid using GHK-Cu
