Extra caution is appropriate in patients with active cancer, recent cancer, unexplained masses, unexplained weight loss, pregnancy, breastfeeding, known allergy to peptide products, active infection, immune compromise, significant liver or kidney disease, active inflammatory or autoimmune disease flares, unusual clotting history, uncontrolled cardiovascular disease, use of chemotherapy or immune-modifying biologic therapy, and competitive athletes subject to anti-doping rules

Anemia, fatigue Poor memory, memory loss, confusion, delirium and paranoia Shortness of Breath (also may indicate low iron) Feeling unstable, dizzy, or off-balance Swollen tongue, reduced taste buds Hyper-pigmentation of the skin, yellowing of the skin Neurological disorders (numbness and tingling in the hands and feet, migraines, neuritis, sciatica, etc.) Mental health symptoms (anxiety, depression) Gastrointestinal symptoms (constipation, diarrhea, dyspepsia) Musculoskeletal (back pain, bursitis, muscle cramps, osteoporosis)
This biological infrastructure makes the gastrointestinal tract a natural target for peptide-based research and two compounds in particular have emerged with substantial published evidence: BPC-157 and KPV
Stimulation of blood vessel formation (angiogenesis): Improved microcirculation around follicles could theoretically enhance nutrient and oxygen delivery, though again this is a preclinical observation
