Sermorelin

Is Sermorelin safe?

Long-term adult use not studied

Sermorelin has a long record of single-dose use for diagnosis. The worry with adult anti-aging use is the hormone it raises. Too much growth hormone and IGF-1 are tied to insulin resistance, fluid retention, joint pain and carpal tunnel syndrome. IGF-1 also promotes cell growth. So a theoretical cancer risk is raised whenever this axis is stimulated for a long time. The 2026 review of performance peptides lists the adverse effects clinicians see in users of this class. They are endocrine disturbances, dysglycemia, fluid retention, musculoskeletal pain and injection site reactions. It also notes the added doubt of compounded or unregulated products of unknown makeup. No long-term safety study of sermorelin in healthy adults exists. 112
