Without intervention, it remains visible indefinitely
The net result is a molecule that resists enzymatic breakdown considerably better than an unmodified sequence
mechanism unexplained Relative contributions of direct peptide effects versus downstream IGF-1 actions inadequately characterized Long-term receptor sensitivity and potential for desensitization inadequately studied Individual patient variability in response not well-characterized Potential for differential effects based on endogenous growth hormone status unclear Long-Term Safety Considerations Critical safety questions remain unanswered regarding chronic peptide administration: Cardiovascular safety concerns FDA warnings cite risks of increased heart rate, systemic vasodilation, flushing, and transient hypotension Immunogenicity risks FDA identifies both peptides as potentially immunogenic with risk of serious immune reactions including anaphylaxis Cancer risk theoretical concern that chronic growth hormone/IGF-1 elevation could promote cellular proliferation

13 In the SURPASS-4 trial (phase III), participants taking tirzepatide showed a much lower occurrence of composite kidney endpoint (time to first occurrence of eGFR decline of at least 40% from baseline, end-stage kidney disease, death due to kidney failure, or new onset albuminuria) compared with those who received insulin glargine (HR 0.58)
Kim often keeps patients at lower doses longer rather than pushing quickly to the maximum dose
