- Sermorelin (GHRH analogue)
- Stimulates endogenous GH release via pituitary GHRH receptors
- Pulsatile, preserves circadian rhythm
- None. Negative feedback intact
- Physiological GH studies, metabolic pathway investigation, mitochondrial biogenesis research
- Ideal for studies requiring preserved endogenous regulation and physiological hormone patterns
- Recombinant GH
- Direct hormone replacement
- Continuous steady-state elevation
- Complete. Shuts down endogenous production
- Dose-response studies, receptor saturation experiments, IGF-1 independent pathway investigation
- Required when supra-physiological GH levels are the research objective, but confounds natural regulatory studies
- Ipamorelin (ghrelin mimetic)
- Growth hormone secretagogue receptor (GHSR) agonist
- Pulsatile but does not preserve circadian amplitude
- Minimal. Some axis adaptation at chronic high dose
- Appetite regulation studies, ghrelin pathway investigation, neuropeptide interaction research
- Useful for ghrelin-specific pathway studies but introduces confounding appetite and gastric motility effects
- MK 677 (oral GHSR agonist)
- Orally bioavailable ghrelin receptor agonist
- Sustained elevation with blunted peaks
- Moderate. Reduces natural pulse amplitude over time
- Chronic GH elevation studies, oral delivery protocols, long-duration metabolic intervention research
- Convenient for extended protocols but less useful for pulsatility-dependent metabolic research
- This comparison underscores the critical trade-off in energy metabolism research: sermorelin preserves the regulatory biology you're often trying to study, while alternatives either replace it entirely (recombinant GH) or introduce secondary signalling pathways (ghrelin mimetics) that confound metabolic outcome interpretation.
