BPC & BPC-157
A pentadecapeptide derived from a protective protein found in human gastric juice. It is highly regarded for its systemic healing properties.
It accelerates wound healing by upregulating Early Growth Response 1 (EGR-1) and stimulating the expression of Vascular Endothelial Growth Factor (VEGF), which promotes angiogenesis (the formation of new blood vessels).
It modulates the nitric oxide (NO) system to control blood flow and protects the mucosal lining of the GI tract.
KPV (Lysine-Proline-Valine)
A C-terminal tripeptide fragment of alpha-melanocyte-stimulating hormone (\alpha-MSH).
It exerts potent anti-inflammatory effects by inhibiting the NF-\kappaB signaling pathway, which reduces the production of pro-inflammatory cytokines. It is particularly effective in the gut and skin, often researched for its ability to stabilize mast cells and reduce allergic inflammation.
LL-37
The only human member of the cathelicidin family of antimicrobial peptides.
It acts as a primary effector of the innate immune system. LL-37 can physically disrupt bacterial membranes through its amphipathic structure and can also modulate the host immune response by attracting neutrophils and T-cells.
Beyond its "natural antibiotic" role, it assists in re-epithelialization during the wound-healing process.

A naturally occurring mitochondrial-derived peptide (MDP).
Functions as a cytoprotective factor, particularly against oxidative stress. It interacts with the Bax protein to prevent apoptosis (programmed cell death) and stabilizes mitochondrial membrane potential.
Studied for its neuroprotective effects and its role in improving insulin sensitivity.
SS-31 (Elamipretide)
A cell-permeable peptide that specifically targets the inner mitochondrial membrane.
It binds to cardiolipin, a phospholipid essential for mitochondrial structure. By stabilizing cardiolipin, SS-31 prevents its oxidation and maintains the efficiency of the electron transport chain.
This results in decreased production of reactive oxygen species (ROS) and increased ATP (energy) production.
