Noopept vs Ipamorelin
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Noopept
Noopept (N-phenylacetyl-L-prolylglycine ethyl ester) is a peptide-derived nootropic developed in Russia. While technically a dipeptide prodrug rather than a true peptide, it's often discussed alongside peptide nootropics.
Full details →Ipamorelin
Ipamorelin is a selective growth hormone secretagogue that stimulates the release of growth hormone from the pituitary gland without significantly affecting cortisol or prolactin.
Full details →Side-by-Side Comparison
| Aspect | Noopept | Ipamorelin |
|---|---|---|
| Mechanism | Metabolized to cycloprolylglycine which modulates AMPA and NMDA receptors, increases NGF and BDNF expression, and provides neuroprotective effects through antioxidant mechanisms. | Acts as a ghrelin mimetic, binding to the ghrelin receptor (GHS-R) in the pituitary to stimulate GH release. Highly selective with minimal effect on other hormones. |
| Typical Dosage | Oral: 10-30mg daily, typically divided into 2-3 doses. Sublingual use may enhance absorption. Some users go higher but effects may plateau. | Typical dosing ranges from 200-300mcg administered 2-3 times daily, often combined with CJC-1295. |
| Administration | Oral or sublingual administration. Unlike most peptides, it's orally bioavailable. Can be taken with or without food. | Subcutaneous injection. Best results when administered fasted or before sleep. Often stacked with GHRH peptides. |
| Side Effects | Headache (often from choline depletion), irritability, insomnia if taken late, and occasional brain fog during initial use. | Generally well-tolerated. May cause mild headaches, lightheadedness, or increased hunger initially. |
