Browse peer-reviewed studies from PubMed with plain-language summaries. Search by keyword or filter by peptide.
Peptides are short chains of amino acids that act as signaling molecules in the body, influencing processes like hormone regulation, immune response, and tissue repair. Researchers are studying them for applications ranging from metabolic health to neuroprotection. Pepdox collects peer-reviewed studies from PubMed and pairs them with plain-language summaries so you can follow the science yourself.
Warning: Most peptides are not approved by the FDA for human use and are sold for research purposes only. Self-administering peptides carries real risks including contamination, incorrect dosing, and unknown long-term side effects. Nothing on this site is medical advice.
A dual GIP and GLP-1 receptor agonist approved for type 2 diabetes and obesity.
A synthetic peptide fragment of thymosin beta-4, researched for wound healing and tissue repair.
A synthetic pentadecapeptide derived from human gastric juice, studied for its regenerative and protective properties.
A mitochondria-derived peptide encoded in the mitochondrial 12S rRNA, studied for its roles in metabolic regulation, insulin sensitivity, and longevit…
Critical limb ischemia (CLI) represents a severe vascular complication of type 2 diabetes, primarily driven by impaired angiogenic capacity, and frequently results in limb amputation or mortality. Here, we investigated the therapeutic potential of ti…
The year 2025 represented a turning point in metabolic research, marked by advances that combined unprecedented clinical efficacy with deep mechanistic insight. Landmark obesity trials redefined therapeutic expectations, with head-to-head and combina…
OBJECTIVE: Obesity is a chronic disease that results in increased morbidity and mortality if left untreated. Tirzepatide is a glucose-dependent insulinotropic polypeptide/glucagon-like peptide-1 receptor agonist approved in the United States for the…
BACKGROUND: Overweight and obesity are increasingly common in adults with type 1 diabetes (T1D), contributing to insulin resistance, higher insulin requirements, and greater cardiometabolic burden. Tirzepatide, a dual glucose-dependent insulinotropic…
