On the positive side, in a diabetic animal model, niacin supplementation increased endothelial growth factors, promoted migration, sprouting, and survival of endothelial cells and mediated vascular remodeling following occlusion of the middle cerebral artery [82]
The article on how long peptides last at room temperature quantifies this degradation rate, and the answer is sobering for anyone who has been careless with storage

Immune Modulation: The peptide's effects on inflammatory pathways suggest caution for: Active autoimmune conditions Immunocompromised individuals Those taking immunomodulatory medications Populations Requiring Extra Caution Avoid or Use Extreme Caution: Active cancer or history of cancer Pregnancy or breastfeeding Children and adolescents Severe cardiovascular disease Active infections Immediately pre or post-surgery (without medical guidance) Drug Interactions Theoretical Interactions Given BPC-157's mechanisms, theoretical interactions exist with: Medications Affecting NO System: Nitrates (nitroglycerin, isosorbide) PDE5 inhibitors (sildenafil, tadalafil) Some blood pressure medications Reasoning: Combined NO system effects Anticoagulants and Antiplatelets: Warfarin Aspirin Clopidogrel Direct oral anticoagulants Reasoning: Angiogenic effects may affect bleeding Growth Hormone and Related: HGH IGF-1 Other growth-promoting compounds Reasoning: Additive growth factor effects Immunomodulators: Corticosteroids TNF-alpha inhibitors Other immunosuppressants Reasoning: Overlapping immune effects NSAIDs A Special Case Interestingly, while drug interactions are generally concerning, research suggests BPC-157 may protect against NSAID damage
