Hello!
What is the risk of antibody formation when injecting peptides like GHK-Cu or BPC-157?
More specifically, is there a possibility that the body could recognize these peptides as foreign and develop antibodies against them - and potentially even cross-react with the body’s own endogenous equivalents (e.g. naturally occurring GHK)?
Is this mainly a theoretical concern, or has it been observed in practice?
Any insights, research, or personal experiences would be greatly appreciated.
