MATERIALS AND METHODS BPC 157 Synthetic pentadecapeptide BPC 157, GEPPPGKPADDAGLV, M.W

Subcutaneous (SubQ) injection delivers GHK-Cu into the fat layer just beneath the skin, from where it absorbs steadily into systemic circulation

Studies comparing delivery methods show topical formulations achieve only a fraction of the bioavailability that subcutaneous injection provides

Dihexa: a spectacular cell-culture number, zero human trials, an unexamined cancer-pathway question, and a retraction notice on the papers that produced the legend

Mechanistically, scientific literature suggests BPC 157 may influence several repair pathways at once, including signaling involved in new blood vessel formation (angiogenesis), nitric oxide-related pathways (important for blood flow and tissue signaling), and growth-factor activity that supports cell migration and remodeling during healing
