@stealthprotocols: Peptides are not one category of compounds doing the same thing. BPC-157, TB-500, KPV, and GHK-Cu are commonly discussed around inflammatory signaling and tissue-repair research. Semax and Selank are studied in a completely different lane involving the nervous system, cognition, stress response, and neurotransmitter signaling. That is the part most people miss. Calling something a “peptide” tells you very little about what it actually does. Different peptides can interact with completely different receptors and biological pathways. **Same molecular category. Very different signals.** The mechanism matters more than the nickname.
