Ipamorelin

The gentlest growth hormone secretagogue, usually the first one people research.

What it is

Ipamorelin is a selective ghrelin receptor agonist that prompts the pituitary to release a pulse of growth hormone.

How it works

It triggers GH release without meaningfully raising cortisol or prolactin, which separates it from older secretagogues like GHRP-6. The pulse mimics the natural rhythm rather than flooding the system.

What it is researched for

• Deeper sleep
• Recovery between training sessions
• Body composition support

Research status

Not approved as a medicine. Widely used in research settings.

What to watch for

• Head rush or flushing right after injection
• Water retention and tingling hands at higher doses
• Food within an hour blunts the pulse

Storage

Lyophilised powder keeps in the freezer or fridge, away from light. Once reconstituted with bacteriostatic water, keep it refrigerated and use it within about four weeks.

Common questions

Why take it at night?

Natural GH release peaks during early deep sleep. Dosing before bed stacks the pulse on top of that rhythm.

Why pair it with CJC-1295?

CJC-1295 raises the size of the pulse, ipamorelin triggers it. Together they produce a bigger release than either alone.
