Side-by-Side Comparison

Aspect	Cerebrolysin	Thymosin Alpha-1
Dose Range	2150 mg–4300 mg	1.6 mg–3.2 mg
Frequency	1x daily	Less than daily
Cycle Length	1–2 weeks	4–12 weeks
Route	intramuscular	subcutaneous
Mechanism	Contains multiple neurotrophic factors that promote neuroplasticity, reduce neuronal apoptosis, and support synaptic function. Has both neurotrophic and neuroprotective properties.	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	Clinical dosing: 10-30ml IV daily for acute conditions. Research use: 5-10ml IM daily for cognitive enhancement. Treatment courses typically last 10-20 days.	Clinical dosing typically ranges from 1.6mg to 6.4mg administered subcutaneously 2-3 times weekly. Research protocols may vary.
Administration	Administered via intramuscular or intravenous injection. IV administration is typically used in clinical settings. IM can be used for research purposes.	Subcutaneous injection. Often used in cycles or as part of comprehensive immune support protocols.
Side Effects	Generally well-tolerated. May cause dizziness, headache, sweating, or injection site reactions. Rare cases of agitation or confusion.	Generally well-tolerated. Rare side effects include injection site reactions, mild flu-like symptoms, and temporary fatigue.
