Tissue Healing and Repair BPC 157 is most well-known for its proposed tissue healing properties, including tendons, ligaments, muscles, and bones, by the following mechanisms: Impacting growth factors: It may activate the JAK2 signaling pathway and increase growth hormone receptor activity, particularly in tendon cells, enhancing their ability to respond to growth hormone
A 2009 review in the Journal of Biomaterials Science summarized GHK-Cu's capacity to upregulate collagen synthesis, stimulate elastin production, and increase glycosaminoglycan deposition in dermal tissue models
Dosing, cost, and when to choose each one
GHK-Cu, BPC-157, and TB-500 are studied along different mechanistic lines: GHK-Cu for ECM and collagen signaling, BPC-157 for angiogenic and tissue-repair pathways, and TB-500 for actin regulation and cell migration
