Side-by-Side Comparison

AspectThymosin Alpha-1Epithalamin
MechanismEnhances T-cell function and maturation, stimulates dendritic cell activity, and modulates cytokine production. Promotes the differentiation of stem cells into mature T lymphocytes.Similar to Epitalon, it stimulates telomerase production and may help maintain telomere length. Also regulates melatonin synthesis and circadian rhythms.
Typical DosageClinical dosing typically ranges from 1.6mg to 6.4mg administered subcutaneously 2-3 times weekly. Research protocols may vary.Research dosing: 10-20mg daily for 10-20 day cycles. Often administered 1-3 times per year in long-term protocols.
AdministrationSubcutaneous injection. Often used in cycles or as part of comprehensive immune support protocols.Intramuscular or subcutaneous injection. Natural extract may have more variable composition than synthetic Epitalon.
Side EffectsGenerally well-tolerated. Rare side effects include injection site reactions, mild flu-like symptoms, and temporary fatigue.Generally well-tolerated. May affect sleep patterns. Less characterized than synthetic Epitalon.
