Thymalin vs VIP (Vasoactive Intestinal Peptide)
An educational, source-based comparison of Thymalin and VIP (Vasoactive Intestinal Peptide) — how each peptide works, what it's researched for, and what to know before going deeper.
A polypeptide complex extracted from calf thymus, studied as an immune bioregulator. Research suggests restoration of T-cell function and thymic activity in aged and immunocompromised cohorts.
- Immunosenescence
- Recovery from infection in elderly cohorts
- Adjunct in chronic inflammatory conditions
- • Approved in Russia; not FDA-approved.
- • Mixture composition is not fully characterized.
Neuropeptide researched for immune modulation and lung protection.
A 28-amino-acid neuropeptide with broad immunomodulatory, anti-inflammatory, and bronchodilatory effects. Acts via VPAC1 and VPAC2 receptors to regulate T-cell function, macrophage polarization, and airway smooth muscle tone.
- Acute respiratory distress syndrome (ARDS)
- Chronic inflammatory conditions
- Autoimmune modulation
- Bronchial asthma and COPD
- • Short half-life limits therapeutic utility; analogs in development.
- • Not FDA-approved in native form.
