Cortagen (20 mg Vial)
Cortagen is a synthetic tetrapeptide (Ala-Glu-Asp-Pro) that belongs to the Khavinson bioregulator class, studied for its neuroprotective and neuroregenerative properties[1][2]. Research indicates Cortagen may support peripheral nerve regeneration, enhance cognitive function, reduce oxidative stress in neural tissues, and promote cellular repair mechanisms without significant adverse effects at therapeutic doses[3][4].
Quick Reference
What is Cortagen?
Research overview based on the cited scientific literature.
• Goal: Support neural regeneration, cognitive function, and cellular repair mechanisms over time[1][3].
• Storage: Lyophilized frozen; reconstituted refrigerated; avoid repeated freeze–thaw.
Storage Instructions
Proper storage preserves peptide quality[10].
• Lyophilized: Store at −20 °C (−4 °F) for long-term; 2–8 °C (35.6–46.4 °F) acceptable for short-term (weeks to months).
• Reconstituted: Refrigerate at 2–8 °C (35.6–46.4 °F); use within 4 weeks and avoid freeze–thaw.
• Allow vials to reach room temperature before opening to reduce condensation uptake.
How is Cortagen studied?
Cortagen (Ala-Glu-Asp-Pro) is a synthetic tetrapeptide derived from amino acid analysis of the natural brain cortex preparation Cortexin[3]. It acts as a gene expression modulator and epigenetic regulator, influencing the synthesis of proteins involved in neuronal growth, differentiation, and stress resistance[6][7]. Preclinical studies demonstrate that Cortagen can upregulate neurotrophic factors, reduce oxidative stress markers, and accelerate peripheral nerve regeneration—increasing nerve fiber growth rate and conduction velocity by 27–40% in injury models[1]. In chronic cerebral ischemia models, Cortagen improved behavioral recovery and protected against oxidative damage[2].
What does the research report about Cortagen?
Observations from preclinical and limited clinical literature.
• Supports peripheral nerve regeneration with improved growth rate and conduction velocity in injury models[1].
• Demonstrates neuroprotective effects in ischemia models by reducing lipid peroxidation and preserving antioxidant enzyme activity[2].
• May enhance cognitive function and memory through promotion of synaptic plasticity and neurite outgrowth[4][5].
• Shows gene expression modulation in cardiac and neural tissues with broad regulatory effects[3][6].
• Generally well tolerated with no significant adverse effects observed at therapeutic doses in animal studies[5].
• Occasional mild injection-site reactions (redness/itch) may occur with subcutaneous administration.

What are the limitations of the research on Cortagen?
Evidence should be interpreted within the population, experimental model, formulation, route, outcome measures, and study design used in each cited source. Preclinical or early-stage findings do not establish clinical efficacy, safety, or approved human use. Where human evidence is available, results should not be generalized beyond the populations and conditions actually studied.
