(PubMed) That doesnt automatically translate to healthier, and it certainly doesnt translate to safe to combine with other secretagogues indefinitely. A clinician-friendly framework to evaluate any peptide stack you see online If you want the full decision logic, use Metos pillar: Heres the condensed version Id use in a consult: Step 1: Define the outcome in one sentence Not fat loss. Instead: Reduce visceral adiposity and improve triglycerides in 12 weeks, or Improve return-to-running tolerance after a tendon injury. Step 2: Grade evidence, not enthusiasm Use three buckets: A: Human outcomes evidence (best) B: Human biomarker evidence (useful but indirect) C: Preclinical/mechanistic only (hypothesis) Example: Semaglutide for weight loss: A CJC-1295 for raising IGF-1: B BPC-157/TB-500 for tendon healing: often C low B , depending on claim Step 3: Avoid redundancy If two compounds push the same pathway, youre more likely to get side effects than synergy
