Protocolo de Dosificación

3 Fases

Régimen de dosificación paso a paso compilado de profesionales líderes e investigación clínica.

1
Neuro-Loading Phase
Weeks 1-3
Dosis
20 mg/day
Frecuencia
Daily (morning)
Vía
Subcutaneous injection (abdominal)

Higher initial loading to achieve CNS-level epigenetic activation. Subcutaneous injection provides reliable systemic delivery for this ultrashort peptide (430 Da) which readily crosses the blood-brain barrier. Take on empty stomach.

2
Active Bioregulation
Weeks 4-6
Dosis
10 mg/day
Frecuencia
Daily
Vía
Subcutaneous injection (abdominal)

Reduced maintenance dose sustains epigenetic changes initiated during loading. Neurotrophic factor upregulation should be established. Combine with cognitive activity for synergistic neuroplasticity.

3
Consolidation & Taper
Weeks 7-8
Dosis
10 mg every other day
Frecuencia
Every other day
Vía
Subcutaneous injection (abdominal)

Gradual taper permits assessment of sustained neuroprotective effects. Khavinson data shows cortical gene expression changes persist 4-6 months. Plan next course accordingly.

Reconstitución

Supplied as lyophilized powder. Reconstitute with 2 mL bacteriostatic water per 20 mg vial = 10 mg/mL. Swirl gently until fully dissolved — do not shake. Cortagen's ultrashort size (430 Da) ensures rapid dissolution and absorption from the subcutaneous depot.

Ciclado

Standard Khavinson protocol: 2-3 week active courses repeated every 4-6 months. Neuroprotective effects are cumulative across courses. Allow minimum 3-month inter-course interval for epigenetic consolidation.

Almacenamiento

Lyophilized: -20°C for 24+ months. Reconstituted: 2-8°C, use within 14 days. Protect from moisture and UV light.

Administración

Subcutaneous injection into abdominal fat pad. Rotate injection sites with each dose to prevent lipodystrophy. Use insulin syringe for precise dosing. At 430 Da, Cortagen readily crosses the blood-brain barrier after subcutaneous absorption, providing reliable CNS delivery while avoiding first-pass hepatic metabolism.

  • BDNF upregulation enhances synaptic plasticity, long-term potentiation, and memory encoding
  • NGF pathway activation supports cholinergic neuron survival — critical for Alzheimer's research
  • Neurotrophic gene expression increases are sustained beyond active supplementation period

Linkova et al. (2012) Cell and Tissue Biology; Trofimov et al. (2015)

Neural ROS Defense

Antioxidant Enzyme Activation

Cortagen activates transcription of antioxidant defense genes (SOD2, catalase, glutathione peroxidase) specifically in cortical neurons, reducing oxidative damage — the primary driver of brain aging.

  • SOD2 upregulation neutralizes superoxide radicals in neuronal mitochondria
  • Catalase activation reduces hydrogen peroxide accumulation in neural tissue
  • Combined antioxidant gene activation mimics caloric restriction neuroprotection profile

Khavinson et al. (2014) PMID: 25826986; Linkova et al. (2012)

Neuronal Survival

Anti-Apoptotic Gene Expression

Cortagen shifts the Bcl-2/Bax ratio toward cell survival in cortical neurons, reducing apoptotic cell death under ischemic, excitotoxic, and age-related stress conditions.

  • Bcl-2 and Bcl-xL upregulation inhibits mitochondrial apoptosis pathway activation
  • Reduced caspase-3 activation in cortical neurons under oxidative stress
  • Preservation of neural networks that would otherwise undergo age-related attrition

Khavinson (2016) Biology Bulletin Reviews; Trofimov et al. (2015)

Cómo Funciona Cortagen

Cortagen is a synthetic tetrapeptide bioregulator that acts primarily on the brain and central nervous system. It interacts with DNA regulatory sequences in neural cells to modulate gene expression related to antioxidant enzyme production, neurotransmitter synthesis, and the balance between pro-oxidant and antioxidant processes. Cortagen has been shown to normalize cerebral cortex function, restore the balance of excitatory and inhibitory neurotransmission, and protect neurons from oxidative damage in aging models.

Preguntas Frecuentes

Cortagen (CAS: 335591-03-2) is a research compound, with a molecular weight of 430.40 Da in the Specialty / Research category. Cortagen is a synthetic tetrapeptide bioregulator that acts primarily on the brain and central nervous system. It interacts with DNA regulatory sequences in neural cells to modulate gene expression related to antioxidant enzyme production, neurotransmitter synthesis, and the balance between pro-oxidant and antioxidant processes. Researchers commonly investigate Cortagen for CNS bioregulation and neuroprotection, Oxidative stress balance in neural tissue, Age-related cognitive decline. Every vial from MiPeptidos includes batch-specific analytical documentation.
To reconstitute your Cortagen 20mg vial, let it reach room temperature for about 15-20 minutes out of the freezer. Slowly inject 3-5mL of bacteriostatic water along the inside wall of the vial — never aim directly at the peptide cake. Gently swirl until the powder fully dissolves; never shake, as this can denature the peptide. Store reconstituted Cortagen at 2-8°C and use within 30 days. MiPeptidos includes bacteriostatic water for purchase alongside all peptides.
Cortagen (Ala-Glu-Asp-Pro, 430 Da) is the cerebral cortex-targeting member of the Khavinson tetrapeptide family, while Cardiogen (489 Da) targets cardiac tissue. Cortagen proline C-terminus directs it toward neuronal gene expression regulation and neuroprotection. It has been studied in Russian literature for age-related cognitive decline and neurodegenerative conditions. The tetrapeptide bioregulator approach pioneered by Khavinson represents a unique field of peptide pharmacology. MiPeptidos stocks the complete set.
Store lyophilized Cortagen at -20°C for maximum long-term stability — properly stored, it remains potent for 24+ months. Once reconstituted with bacteriostatic water, keep it refrigerated at 2-8°C and use within 30 days. In research applications, Cortagen has a reported half-life of Short; rapidly absorbed and distributed as an ultrashort peptide, which informs dosing frequency and protocol design. Avoid repeated freeze-thaw cycles and protect from direct light. MiPeptidos ships every order with cold-chain packaging to maintain integrity during transit.
Every Cortagen order from MiPeptidos includes a batch-specific Certificate of Analysis. Our current batch (HR-CRTG-2600315, tested January 4, 2026) shows 99.4% purity by HPLC, mass spectrometry confirmation at 430.40 Da, endotoxin levels below 0.1 EU/mg, and passing sterility per USP <71>. This level of documentation ensures you can verify compound identity and purity before beginning your research. MiPeptidos also offers bulk pricing on orders of 50+ vials — contact info@mipeptidos.com.
