This comparison does not assign a generated winner or score.

  • Active malignancy
  • IGF-1 promotes tumour cell proliferation, angiogenesis, and anti-apoptotic signalling via PI3K/AKT and MAPK pathways
  • Accelerated tumour growth, increased metastatic potential, reduced apoptotic response to chemotherapy
  • GLP-1 agonists (semaglutide, tirzepatide) for fat reduction without GH pathway activation
  • Disrupted hypothalamic-pituitary axis
  • Absence of functional somatotrophs or GHRH receptors eliminates ability to generate endogenous GH surge
  • No therapeutic effect; unmasking of latent adrenal insufficiency if ACTH reserves are impaired
  • Exogenous GH (if clinically indicated and axis is non-recoverable); incretin-based therapies for metabolic intervention
  • Pregnancy (Category X)
  • Supraphysiologic GH/IGF-1 disrupts foetal growth plate ossification and organ maturation timing; animal studies show teratogenicity
  • Foetal loss, skeletal malformations, intrauterine growth abnormalities
  • Delay therapy until post-lactation; lifestyle intervention during pregnancy
  • Diabetic retinopathy (proliferative)
  • IGF-1 upregulates VEGF, driving neovascularisation in ischaemic retinal tissue
  • Worsening macular oedema, vitreous haemorrhage, vision loss despite stable glycaemic control
  • Optimise glucose control; anti-VEGF intravitreal therapy; delay GH secretagogues until retinopathy stabilises
  • Hypersensitivity to mannitol or tesamorelin
  • IgE-mediated or non-IgE immune reaction to peptide structure or excipient
  • Anaphylaxis, angioedema, bronchospasm, or delayed hypersensitivity reaction
  • Avoidance; no desensitisation protocol exists for GHRH analogues
  • Critical illness
  • Functional GH resistance (elevated GH but suppressed hepatic IGF-1 production due to inflammatory cytokines)
  • No metabolic benefit; increased infection risk, worsened hyperglycaemia
  • Defer until recovery; standard critical care metabolic support
