Cortagen
Brain cortex bioregulator peptide from the Khavinson series. Short peptide (2-4 amino acids) that targets specific tissue for gene expression regulation and organ health optimization.
Beginner Basics
Plain-English guide to Cortagen
What it does
This is a short chain of amino acids that researchers believe helps support brain health, mental sharpness, and blood flow to the brain. It's studied for potentially helping with memory and protecting brain tissue.
Typical dose
Researchers typically use 10-20 micrograms once or twice daily, usually given as an injection under the skin or dissolved under the tongue.
When to inject
Most commonly used in the morning; if taking twice daily, the second dose is typically in the afternoon. Taking it on an empty stomach may work best.
Storage
Keep the dry powder frozen at -20°C (a regular freezer works). Once you mix it with liquid, store it in a regular refrigerator at 2-8°C and keep it away from direct light.
First-timer tip
Start with the lowest dose (10 mcg once daily) for the first week to see how your body responds before moving to higher amounts or twice-daily dosing.

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

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.
