    neuropeptide involved in pain perception and inflammation

    Substance P (SP) is a neuropeptide that functions as a neurotransmitter and neuromodulator, playing a key role in pain perception by transmitting pain signals to the central nervous system. It is also involved in inflammatory processes and can influence hair growth by affecting the local immune response and blood flow in the scalp.

      learn GHK-Cu

      • GHK-Cu: What is the most recommended product? No GHK-Cu product has published human trial evidence for hair loss, so none can be ranked on efficacy; what separates products is formulation quality — purity, stability and third-party testing — and the FDA lists GHK-Cu among bulk substances that may present significant safety risks in compounding.
      • GHK-Cu: Does it have side effects or is it completely safe? For topical cosmetic use, the small laboratory evidence base found GHK-Cu non-irritating, and reported reactions are local and uncommon; for injected or oral use there is effectively no human safety data, and the FDA lists GHK-Cu among bulk substances that may present significant safety risks in compounding.
