Drug Interaction Checker
Check for potential interactions between peptides, prescription medications, supplements, and hormone therapies. Add two or more substances below to see AI-analyzed interaction risks, severity levels, and clinical recommendations.
Why Check Peptide Interactions?
Peptide therapies are increasingly used alongside prescription medications, supplements, and hormone replacement therapy. While many peptides have favorable safety profiles, interactions can occur — especially with blood thinners, insulin-sensitizing agents, immunomodulators, and hormone therapies.
Our AI-powered checker analyzes known and theoretical interactions based on mechanism of action, metabolic pathways, and published clinical data. Results are categorized by severity: major, moderate, or minor.
Common Interactions to Be Aware Of
BPC-157 + Blood Thinners
BPC-157 may promote angiogenesis and affect coagulation pathways. Use caution when combining with warfarin, heparin, or other anticoagulants.
Semaglutide + Insulin / Sulfonylureas
GLP-1 receptor agonists like semaglutide can potentiate hypoglycemia when combined with insulin or sulfonylureas. Dose adjustments may be required.
CJC-1295 + Testosterone Replacement
Growth hormone secretagogues may synergize with TRT for body composition but should be monitored for IGF-1 levels and insulin sensitivity changes.
Thymosin Alpha-1 + Immunosuppressants
Immune-modulating peptides may counteract immunosuppressive medications. Patients on transplant drugs or autoimmune treatments should consult their provider.
