A short synthetic tripeptide studied for localized anti-inflammatory and mucosal protective effects.
Acts on nitric oxide pathways and prostaglandin synthesis similarly to BPC-157 fragments. Research suggests it stabilises gut mucosal integrity, reduces local inflammatory markers, and may protect against NSAID-induced gastric injury.
PDA shares structural similarity with biologically active fragments of BPC-157 and has been studied in gastrointestinal injury models. It appears to work through multiple anti-inflammatory mechanisms without significant systemic hormonal effects.
Often studied as a complement to BPC-157 in gut healing stacks, PDA may offer more targeted mucosal protection with a simpler molecular structure.
