Side-by-Side Comparison

AspectThymosin Alpha-1AOD-9604
MechanismEnhances T-cell function and maturation, stimulates dendritic cell activity, and modulates cytokine production. Promotes the differentiation of stem cells into mature T lymphocytes.Stimulates lipolysis (fat breakdown) and inhibits lipogenesis (fat accumulation) without affecting blood sugar or growth. Works specifically on adipose tissue through a mechanism independent of GH receptors.
Typical DosageClinical dosing typically ranges from 1.6mg to 6.4mg administered subcutaneously 2-3 times weekly. Research protocols may vary.Research dosing typically ranges from 250-500mcg daily, often split into morning and afternoon doses. Some protocols use higher doses up to 1mg.
AdministrationSubcutaneous injection. Often used in cycles or as part of comprehensive immune support protocols.Subcutaneous injection, typically in the abdominal area. Best administered on an empty stomach. Can be combined with exercise for enhanced effects.
Side EffectsGenerally well-tolerated. Rare side effects include injection site reactions, mild flu-like symptoms, and temporary fatigue.Generally well-tolerated. May cause headaches, injection site reactions, or temporary lethargy. Does not affect blood glucose like full GH.
