Side-by-Side Comparison

Aspect	PE-22-28	Pinealon
Dose Range	500 mcg–2 mg	5 mg–10 mg
Frequency	1x daily	1x daily
Cycle Length	1–2 weeks	1–2 weeks
Route	subcutaneous	subcutaneous
Mechanism	Derived from the protein that is deficient in SAMP8 mice. May work by inhibiting protein phosphatase 2A methylesterase, thereby affecting memory-related signaling pathways.	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.
Typical Dosage	Research protocols vary. Intranasal dosing has been studied at various concentrations. Optimal human dosing not established.	Typical dosing: 10-20mg daily, taken in divided doses. Often used in cycles of 10-20 days.
Administration	Intranasal administration preferred for CNS delivery. Research compound with limited human use data.	Can be taken orally (capsules) or sublingually. Best absorbed on an empty stomach. Often combined with other neuroprotective peptides.
Side Effects	Very limited human data. Primarily studied in animal models for safety and efficacy.	Generally well-tolerated. Limited reported side effects. May affect sleep patterns initially.
