Mechanism
GHRH analogues vs GHS-R1a (ghrelin-mimetic) secretagogues
Two different ways to stimulate the body's own growth-hormone output. GHRH analogues like tesamorelin mimic the natural releaser; GHS-R1a agonists like ipamorelin mimic ghrelin. Both raise GH, but with different physiology and safety profiles.
Plain-English explanation
Two different ways to stimulate the body's own growth-hormone output. GHRH analogues like tesamorelin mimic the natural releaser; GHS-R1a agonists like ipamorelin mimic ghrelin. Both raise GH, but with different physiology and safety profiles.
Research-level explanation
Tesamorelin has a human-licensed indication (HIV-associated lipodystrophy, US). Ipamorelin / CJC-1295 are research-only compounds without UK or US human therapeutic licensing.
Common misconceptions
| Common claim | More accurate framing |
|---|---|
| GH secretagogues are equivalent to recombinant human growth hormone. | Secretagogues stimulate endogenous pulsatile GH release; rhGH is exogenous replacement. The two have different physiology, regulatory status and safety profiles. |
Safety relevance
Hyperglycaemia risk, IGF-1 surveillance and cardiovascular monitoring apply differently to each molecule per its product information or research protocol.
- Research-only secretagogues are not a validated alternative to licensed obesity or diabetes medicines.
