PE-22-28 vs Thymosin Alpha-1
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
PE-22-28
PE-22-28 is a synthetic peptide fragment derived from research on the SAMP8 mouse model of accelerated aging. It has shown potential for enhancing memory and reducing cognitive decline.
Full details →Thymosin Alpha-1
Thymosin Alpha-1 is a peptide naturally produced by the thymus gland that plays a crucial role in immune system modulation. It is approved in over 35 countries for various conditions including hepatitis B and C.
Full details →Side-by-Side Comparison
| Aspect | PE-22-28 | Thymosin Alpha-1 |
|---|---|---|
| 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. | Enhances T-cell function and maturation, stimulates dendritic cell activity, and modulates cytokine production. Promotes the differentiation of stem cells into mature T lymphocytes. |
| Typical Dosage | Research protocols vary. Intranasal dosing has been studied at various concentrations. Optimal human dosing not established. | Clinical dosing typically ranges from 1.6mg to 6.4mg administered subcutaneously 2-3 times weekly. Research protocols may vary. |
| Administration | Intranasal administration preferred for CNS delivery. Research compound with limited human use data. | Subcutaneous injection. Often used in cycles or as part of comprehensive immune support protocols. |
| Side Effects | Very limited human data. Primarily studied in animal models for safety and efficacy. | Generally well-tolerated. Rare side effects include injection site reactions, mild flu-like symptoms, and temporary fatigue. |
