Research Comparison
Thymosin Alpha 1 vs VIP (Vasoactive Intestinal Peptide)
A side-by-side research comparison of Thymosin Alpha 1 and VIP (Vasoactive Intestinal Peptide) drawn from Cobalt Peptides' peptide database records.
Thymosin Alpha 1
Thymosin Alpha 1 is a synthetic 28-amino acid peptide identical in sequence to the naturally occurring thymic hormone. It has been the subject of an extensive published literature on immunomodulation, describing activity across several immune pathways including T-cell maturation, natural killer cell activation and dendritic cell modulation. Licensed medicines containing thymalfasin exist in some jurisdictions and are prescribed by clinicians; the material supplied here is a research compound and is not one of them.
VIP (Vasoactive Intestinal Peptide)
Vasoactive Intestinal Peptide (VIP) is a 28-amino acid neuropeptide with potent anti-inflammatory, immunomodulatory, and neuroprotective properties. Acting through VPAC1 and VPAC2 receptors, VIP regulates immune function, vascular tone, circadian rhythms, and neurological activity. VIP has been extensively studied in inflammatory, pulmonary, and neurological conditions. Intranasal delivery enables direct CNS access via olfactory and trigeminal pathways, while systemic administration influences immune and vascular systems. It is particularly notable in research involving chronic inflammatory response syndrome (CIRS), respiratory dysfunction, and neuroimmune regulation.
