BPC-157 has been shown to prevent and reverse NSAID-induced ulcer formation in both the stomach and small intestine
There may be one caveat, though
It covers subcutaneous (SubQ) injection, intravenous (IV) infusion, intramuscular (IM) injection, oral NMN, oral NR, intranasal/sublingual formats, and pre-mixed pen or pharmacy liquid options
The stack targets the GH axis (growth and body composition), melanocortin system (pigmentation), copper peptide biology (collagen and ECM remodeling), mitochondrial bioenergetics (NAD+ and sirtuin activation), metabolic triple-agonist signaling (fat oxidation and appetite), IGF-mediated anabolic pathways (lean tissue and repair), and androgenic/anabolic drive (protein synthesis and nitrogen retention)
