Growth axis
Ipamorelin
Used in research for GH pulses, recovery and body composition (often with CJC-1295).

Overview
Ipamorelin is a GHRP/GHS-class peptide studied as a GH-release stimulator with a relatively selective profile in models and limited clinical literature.
What it is used for
Community and research context — not a medical indication or treatment advice.
- GH-release stimulation (GHRP / ghrelin mimetic)
- Sleep and recovery (community discussion)
- Longer-term body composition (narrative)
- Often paired with CJC-1295 (no DAC)
Ipamorelin is a selective GHRP — people discuss sleep, recovery, “GH pulse” and milder stimulation than older GHRPs. It is not a GLP-1 and does not act like semaglutide on appetite. Stacking with CJC-1295 is one of the most common research-forum motifs.
For people learning GHRPs and growth-axis stacks.
How it works
It acts via the ghrelin receptor (GHS-R), stimulating GH release. Relative selectivity (less cortisol/prolactin than some older GHRPs) is often emphasised — caution and medical context still apply.
It acts via the ghrelin receptor (GHS-R1a), stimulating GH pulses. In research practice it is often combined with GHRH analogues (e.g. CJC-1295).
How it is used (research context)
From protocols and documentation — not a dosing guide.
Research: reconstitution, usually SC; timing is often tied to sleep / empty stomach in community narrative. Not a MarcinLabs protocol. IGF-1 and contraindications = clinician.
Key takeaways
- Growth axis / sleep / recovery — not anti-obesity first line
- Common partner: CJC-1295 no DAC
- Effect depends on sleep, stress, age, metabolic status
- Do not confuse with tesamorelin (different molecule type)
