Side Effects
Mild redness, swelling, or itching at the injection site may occur. Usually resolves within 1-2 hours. Rotate injection sites to minimize risk. Apply ice if needed.
Mild headache has been reported in some users, particularly when starting. Usually transient and resolves within 24-48 hours. Ensure adequate hydration.
Rare reports of mild dizziness, particularly with sublingual administration. Sit or lie down if this occurs. Resolve typically within minutes.
Rare reports of mild nausea, especially with sublingual dosing. Usually resolves quickly. Take with food if using sublingual route.
Although rare, allergic reactions to peptide bioregulators are possible, particularly in individuals with sensitivity to bovine-derived products. Symptoms may include rash, itching, swelling, or difficulty breathing. Seek immediate medical attention if allergic symptoms develop. Discontinue use.
Some users report mild sleep disruption, particularly if dosed in the evening. Administer in the morning to minimize this risk.

Reconstitution Guide
Do not use saline or bacteriostatic saline — use only bacteriostatic water for reconstitution
Do not shake the vial vigorously; gentle swirling prevents peptide degradation
Discard immediately if the solution appears cloudy, discolored, or contains visible particles
Use within 30 days of reconstitution when stored at 2–8°C
Do not freeze the reconstituted solution; freezing may denature the peptide
Use the PeptideVolt reconstitution calculator for your exact concentration
Molecular and Pharmacological Data
Cortagen is a short peptide bioregulator (2-4 amino acids) derived from bovine brain cortex tissue that is believed to act as a tissue-specific signaling molecule. It is thought to cross the blood-brain barrier and modulate gene expression in cortical neurons, promoting neuroprotection, enhancing cerebral blood flow, and supporting cognitive function through epigenetic and receptor-mediated pathways. The peptide may also stimulate endogenous production of neuroprotective factors and support neuroplasticity.
Tissue-Specific Gene Expression Regulation
Khavinson bioregulator peptides are proposed to bind to specific cell-surface receptors or intracellular targets in brain cortex tissue, triggering signaling cascades that upregulate neuroprotective genes and downregulate pro-inflammatory genes. This tissue-specific targeting is thought to optimize cortical cell function and longevity.
Cerebral Blood Flow Enhancement
Cortagen may promote vasodilation and improve microcirculation in brain tissue, enhancing oxygen and nutrient delivery to cortical neurons. Improved cerebral perfusion supports cognitive performance and may protect against age-related cognitive decline.
Neuroprotection and Neuroplasticity
The peptide is proposed to stimulate production of neurotrophic factors (such as BDNF) and antioxidant enzymes, reducing neuroinflammation and oxidative stress. This may support synaptic plasticity, memory consolidation, and recovery from neurological stress.
- Cortagen is a short-chain peptide bioregulator derived from bovine brain cortex tissue, part of the Khavinson series of tissue-specific peptides
- Proposed mechanism involves tissue-specific receptor binding and modulation of gene expression in cortical neurons
