How to Reduce Risk: A Practical Safety Checklist If you want a clear safety framework, use this checklist: 1) Confirm the goal define what success means: pain reduction, function, training tolerance, stability set a reasonable timeline that matches connective tissue biology 2) Screen the person, not only the injury review medical history, medications, and contraindications consider baseline labs when clinically appropriate 3) Prioritize quality and sterility avoid unverified research sources use clinician-directed protocols with clear sourcing standards 4) Use conservative protocol strategy avoid unnecessary complexity avoid changing multiple variables every week do not treat peptides as a substitute for sleep, protein, and progressive loading 5) Monitor response and adjust track symptom trend, not only day-to-day fluctuations watch for injection site patterns escalate only when the response is stable This approach reduces risk while improving outcomes, which is the point of responsible care
