Can ipamorelin and sermorelin be stacked?

Not typically. Stack ipamorelin with a GHRH (CJC-1295) or run sermorelin alone. Two GHRHs are rarely combined.

Which raises IGF-1 more?

In practice, ipamorelin + CJC-1295 delivers higher IGF-1 than sermorelin monotherapy.

Ipamorelin vs Sermorelin

Ipamorelin is a selective GHRP; sermorelin is a GHRH. They act on different receptors, so the real question is which class fits your patient — or whether to stack both.

Attribute

Ipamorelin

Sermorelin

Mechanism

Selective ghrelin receptor agonist. Clean pulsatile GH release without cortisol/prolactin spike.

Truncated GHRH (1-29) analog. Restores endogenous pulsatile GH secretion.

Standard dosing

200–300 mcg SC 1–3x daily, often paired with CJC-1295.

200–500 mcg SC nightly, often cycled 5-on/2-off.

Indications

Longevity
Body composition
Sleep and recovery

Adult GH decline
Sleep quality
Body composition

Strengths

Selective, clean side-effect profile
Pairs with any GHRH

Longest clinical track record among GHRHs
Entry-level cost

Cautions

Requires multiple daily doses without CJC pairing

Shorter half-life than CJC-1295
May affect glucose tolerance

Choose Ipamorelin when

Patient wants a clean, cortisol-neutral GH pulse and is fine with multiple daily doses.

Choose Sermorelin when

Patient prefers a single nightly injection and an entry-level GHRH.
