Pinealon vs P21
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Pinealon
Pinealon is a short synthetic peptide developed from research on the pineal gland. It has shown neuroprotective and cognitive-enhancing properties in animal studies.
Full details →P21
P21 is a synthetic peptide derived from Cerebrolysin, specifically designed to mimic the neurotrophic effects of the parent compound. It promotes neurogenesis and has shown cognitive-enhancing properties in research.

| Aspect | Pinealon | P21 |
|---|---|---|
| Mechanism | Penetrates cell membranes and interacts with DNA to regulate gene expression related to neuronal survival and function. May support pineal gland function and melatonin production. | Inhibits glycogen synthase kinase-3β (GSK-3β) and activates CREB signaling pathway. This promotes BDNF expression, neurogenesis in the hippocampus, and synaptic plasticity. |
| Typical Dosage | Typical dosing: 10-20mg daily, taken in divided doses. Often used in cycles of 10-20 days. | Research protocols typically use 1-5mg administered intranasally or subcutaneously. Often used in cycles of 2-4 weeks. |
| Administration | Can be taken orally (capsules) or sublingually. Best absorbed on an empty stomach. Often combined with other neuroprotective peptides. | Can be administered intranasally for direct CNS access or subcutaneously. Best used cyclically rather than continuously. |
| Side Effects | Generally well-tolerated. Limited reported side effects. May affect sleep patterns initially. | Limited data. Reported effects include mild headache, temporary brain fog during initial use, and fatigue. |
