Noopept vs Tesamorelin
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 →Tesamorelin
Tesamorelin is a synthetic analog of growth hormone-releasing hormone (GHRH). It is FDA-approved under the brand name Egrifta for reducing excess abdominal fat in HIV-infected patients with lipodystrophy.
Full details →Side-by-Side Comparison
| Aspect | Noopept | Tesamorelin |
|---|---|---|
| Mechanism | Metabolized to cycloprolylglycine which modulates AMPA and NMDA receptors, increases NGF and BDNF expression, and provides neuroprotective effects through antioxidant mechanisms. | Stimulates the pituitary gland to produce and release growth hormone by binding to GHRH receptors. Increases IGF-1 levels which promotes lipolysis and reduces visceral adipose tissue. |
| 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. | FDA-approved dose: 2mg administered subcutaneously once daily. Research protocols may use various dosing schedules. |
| Administration | Oral or sublingual administration. Unlike most peptides, it's orally bioavailable. Can be taken with or without food. | Subcutaneous injection into the abdomen. Rotate injection sites. Best administered at the same time daily, preferably in the evening. |
| Side Effects | Headache (often from choline depletion), irritability, insomnia if taken late, and occasional brain fog during initial use. | Common side effects include injection site reactions (erythema, pruritus), joint pain, peripheral edema, and muscle pain. May cause elevated blood glucose. |
