The principal changes are as follows: GHK-Cu for non-injectable routes of administration is being removed from Category 1, and GHK-Cu for injectable routes of administration is separately being removed from Category 2
Multiple studies have since been conducted to understand the full action of the peptide, especially in the area of healing gastrointestinal ulceration, which is elaborated on below

In practice, a researcher selecting between them is usually choosing which mechanistic question to probe: vascular and cytoprotective signaling points toward BPC-157, while questions dominated by cell migration and cytoskeletal dynamics point toward TB-500
This steady delivery maintains a uniform concentration of the compound in the blood, preventing sharp spikes or drop-offs that could skew data in long-term metabolic studies
