- Visceral Fat Studies
- Preserves pulsatile lipolytic signalling. Maintains receptor sensitivity across 26+ weeks
- Continuous GH exposure causes receptor desensitisation within 48–72 hours, reducing lipolytic response by 40–60%
- Tesamorelin stimulates endogenous pulsatile secretion; exogenous GH provides continuous non-physiological exposure
- Tesamorelin is the only viable model for studying sustained VAT reduction mechanisms
- Neurodegenerative Research
- Amplifies GH without disrupting hypothalamic-pituitary feedback. Preserves circadian GH rhythms critical for hippocampal neurogenesis
- Exogenous GH suppresses endogenous secretion within 4–6 hours, eliminating natural nocturnal GH pulses that drive BDNF expression
- Natural GH pulses align with sleep architecture; exogenous GH disrupts this temporal coupling
- Studies requiring intact circadian GH patterns must use GHRH analogues, not exogenous GH
- Body Composition Under Caloric Restriction
- Maintains lean mass without water retention or insulin resistance. Nitrogen retention improved 18% vs placebo in hypocaloric protocols
- Therapeutic GH doses cause peripheral insulin resistance and extracellular fluid retention, confounding lean mass measurements
- Pulsatile GH enhances protein synthesis efficiency; continuous GH impairs insulin signalling
- Tesamorelin allows clean separation of GH's anabolic effects from its anti-insulin metabolic effects
- Feedback Regulation Studies
- Preserves negative feedback loop. Elevated IGF-1 appropriately inhibits further GHRH release
- Exogenous GH bypasses hypothalamic regulation entirely, making feedback studies impossible
- Tesamorelin works within the GHRH-GH-IGF-1 axis; exogenous GH replaces it
- Any study examining GH regulatory dynamics requires GHRH stimulation, not GH replacement
