P21 vs Syn-Ake
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
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 | P21 | Syn-Ake |
|---|---|---|
| Mechanism | Inhibits glycogen synthase kinase-3β (GSK-3β) and activates CREB signaling pathway. This promotes BDNF expression, neurogenesis in the hippocampus, and synaptic plasticity. | Acts as a competitive antagonist at the nicotinic acetylcholine receptor, reducing muscle contractions similar to Botox but through a different mechanism. Provides muscle-relaxing effects when applied topically. |
| Typical Dosage | Research protocols typically use 1-5mg administered intranasally or subcutaneously. Often used in cycles of 2-4 weeks. | Topical: 1-4% concentration in serums or creams. Applied 1-2 times daily to target areas like forehead and crow's feet. |
| Administration | Can be administered intranasally for direct CNS access or subcutaneously. Best used cyclically rather than continuously. | Topical application only. Should be applied to clean skin. Often combined with other anti-aging peptides for synergistic effects. |
| Side Effects | Limited data. Reported effects include mild headache, temporary brain fog during initial use, and fatigue. | Generally well-tolerated topically. Rare reports of mild skin irritation or sensitivity. |
