Vilon vs Cortagen
Vilon sits in longevity, while Cortagen sits in cognitive / nootropic — so despite being mentioned together they are used for different things. The table below sets out the differences. We give no dosing guidance.
Side by side, in plain English — what each one is, where they overlap and where they genuinely differ.

The differences that actually matter
They aren't really substitutes: Vilon sits in Longevity while Cortagen sits in Cognitive / Nootropic. People usually pick between them because of a shared secondary effect rather than because they do the same job.
Reported mainly for Vilon: immune rejuvenation, telomere support (per animal data), anti-aging signalling.
Reported mainly for Cortagen: cortical repair signaling, improved cognition after stress, neuroprotection.
What Vilon is
Vilon is a synthetic dipeptide composed of the amino acids lysine and glutamic acid (Lys-Glu), categorized as a bioregulator. Its primary mechanism of action involves influencing gene expression within various physiological systems. As a signaling molecule, Vilon is thought to modulate the activity of specific genes, particularly those associated with the healthy function of the immune, cardiovascular, and reproductive systems, rather than acting through specific classical receptors in a direct binding manner. This
What Cortagen is
Cortagen is a short-chain bioregulator peptide derived from brain tissue, classified as a cytomedin due to its tissue-specific modulatory effects. Its proposed mechanism involves interacting with cellular processes to support neuronal health and function within the cerebral cortex. While not directly binding to a single, specific receptor like many pharmaceutical drugs, Cortagen is understood to influence gene expression and protein synthesis pathways essential for neuroprotection and cellular repair. This action c
How to compare them for yourself
Anecdotes online are noisy because nobody is measuring the same thing. The only comparison that means anything is your own: log each entry with a timestamp, keep the vial ledger honest so you know what you actually got through, pick two or three metrics before you start, and look at the trend after several weeks rather than day to day.
Peptide Wizard does that part for you — Vilon and Cortagen are both in the built-in reference library with a 3D vial, and your history, vial ledger and cost per entry stay private on your device.
FAQ
What is the difference between Vilon and Cortagen?
They aren't really substitutes: Vilon sits in Longevity while Cortagen sits in Cognitive / Nootropic. People usually pick between them because of a shared secondary effect rather than because they do the same job.
Can you log Vilon and Cortagen in the same period?
Plenty of people record more than one peptide at a time. Peptide Wizard keeps a separate vial ledger and entry history for each, so you can see exactly what overlapped and when — it does not recommend combinations or doses.
Which is better, Vilon or Cortagen?
There isn't a universal answer — reported responses vary a lot between individuals, which is why your own log is more informative than anyone else's anecdote. Track one variable at a time and compare your own metrics over several weeks.
