Ipamorelin vs GHRP-2
Comprehensive side-by-side comparison of mechanisms, dosing, side effects, and research
Also: IPAM, NNC 26-0161
A selective growth hormone secretagogue that stimulates GH release without significantly affecting cortisol or prolactin. Considered one of the safest GHRPs.
Also: Growth Hormone Releasing Peptide 2, Pralmorelin
A synthetic hexapeptide that potently stimulates GH release. More potent than GHRP-6 with less appetite stimulation, but still elevates cortisol and prolactin.
Key Comparison Insights
- Both peptides belong to the Growth Hormone category, suggesting similar primary applications.
- These GH secretagogues are frequently combined to enhance growth hormone release.
Detailed Comparison
| Attribute | Ipamorelin | GHRP-2 |
|---|---|---|
| Category | Growth Hormone | Growth Hormone |
| FDA Status | Not FDA Approved | Not FDA Approved |
| Clinical Status | Pre I II III IV FDA | Pre I II III IV FDA |
| Mechanism of Action | Ipamorelin binds to ghrelin receptors (GHSR) in the pituitary gland, triggering growth hormone release. Unlike other GHRPs, it does not stimulate significant ACTH, cortisol, prolactin, or aldosterone release, making it highly selective for GH. | GHRP-2 acts on ghrelin receptors to stimulate GH release from the pituitary. It has the strongest GH-releasing effect among GHRPs but also causes more cortisol and prolactin release than ipamorelin. Less appetite stimulation than GHRP-6. |

|
| Research Summary | Clinical studies show dose-dependent GH release with minimal side effects. Research demonstrates improved bone density in postmenopausal women and potential benefits for muscle mass and recovery. Has been studied for post-surgical recovery. | Studies show it produces the highest GH release among common GHRPs. Research demonstrates reliable diagnostic use for GH deficiency testing. Animal studies show improved muscle mass and recovery. |
Frequently Asked Questions: Ipamorelin vs GHRP-2
What is the difference between Ipamorelin and GHRP-2?
Ipamorelin is a growth hormone peptide that a selective growth hormone secretagogue that stimulates gh release without significantly affecting cortisol or prolactin. considered one of the safest ghrps. GHRP-2 is a growth hormone peptide that a synthetic hexapeptide that potently stimulates gh release. more potent than ghrp-6 with less appetite stimulation, but still elevates cortisol and prolactin. The main differences lie in their mechanisms of action and clinical applications.
Which is better, Ipamorelin or GHRP-2?
Neither is universally "better" - the choice depends on your specific goals. Ipamorelin is typically used for growth hormone purposes, while GHRP-2 is used for growth hormone. Always consult with a healthcare provider to determine which may be appropriate for your situation.
Can Ipamorelin and GHRP-2 be used together?
Some peptide protocols combine multiple compounds for synergistic effects. However, using Ipamorelin and GHRP-2 together should only be considered under medical supervision, as both compounds have their own side effect profiles and potential interactions. Research on their combined use may be limited.
