Peptide Comparison
CerlutenvsSemax
Brain-derived peptide bioregulator complex containing AED, KED, AEDG, and KE peptides that promote neurogenesis through histone binding, restore dendritic spine architecture under neurotoxic conditions, and enhance cognitive recovery in stroke and brain injury patients
A brain-boosting peptide that supercharges your cognitive function by ramping up BDNF—the protein your neurons need to grow, connect, and stay sharp—all delivered through a simple nasal spray.

Applications
Best
suited for
Cerluten
Cognitive recovery following stroke or traumatic brain injury
Cerluten is particularly well-suited for individuals focused on cognitive recovery following stroke or traumatic brain injury. Research and clinical experience suggest meaningful benefits in this area when used as part of a comprehensive treatment approach.
Neuroprotection against age-related cognitive decline and neurodegeneration
Cerluten is particularly well-suited for individuals focused on neuroprotection against age-related cognitive decline and neurodegeneration. Research and clinical experience suggest meaningful benefits in this area when used as part of a comprehensive treatment approach.
Supporting neurogenesis and neuronal repair in aging brain tissue
Cerluten is particularly well-suited for individuals focused on supporting neurogenesis and neuronal repair in aging brain tissue. Research and clinical experience suggest meaningful benefits in this area when used as part of a comprehensive treatment approach.
Comprehensive bioregulatory approach to brain aging using multiple complementary peptide components
Cerluten is particularly well-suited for individuals focused on comprehensive bioregulatory approach to brain aging using multiple complementary peptide components. Research and clinical experience suggest meaningful benefits in this area when used as part of a comprehensive treatment approach.
Semax
Students and Knowledge Workers
If your day revolves around learning, studying, or processing complex information, Semax can be a game-changer. It enhances memory consolidation and recall while improving your ability to focus for extended periods—perfect for exam prep or demanding projects.
Those Seeking Mental Clarity
Brain fog? Semax works by boosting BDNF—the protein that helps neurons communicate effectively. Users often report feeling like the 'mental static' clears away, leaving sharper, more efficient thinking in its place.
Neuroprotection Seekers
Beyond immediate cognitive benefits, Semax offers protective effects for your brain cells. It acts as an antioxidant (especially against copper toxicity) and supports neuronal health—valuable for anyone concerned about long-term brain wellness.
Recovery Support (Under Medical Supervision)
In Russia, Semax is approved for helping stroke patients and those with traumatic brain injuries recover cognitive function. While not FDA-approved for this use elsewhere, the research shows meaningful neuroprotective and neurorestorative properties.

Safety Overview
Cerluten is a peptide extract from cerebral tissue of young animals that is not FDA-approved and lacks rigorous clinical safety data. As an undefined mixture of peptides and proteins from animal sources, quality control and batch consistency cannot be guaranteed. Potential risks include allergic reactions to animal-derived proteins, contamination with microbial pathogens or prions, and unknown long-term immunological effects. No comprehensive safety studies have been conducted in humans, and the active pharmaceutical components have never been identified or standardized. The product exists primarily in Russian and Eastern European medical markets without Western regulatory oversight.
Contraindications
- xKnown hypersensitivity to peptide bioregulators or bovine-derived products
- xPregnancy and breastfeeding — insufficient reproductive safety data
- xActive CNS infection — treat infection before initiating peptide bioregulator therapy
- xPrion disease concerns — although manufacturing processes include purification to remove proteins > 5 kDa, individuals with heightened prion risk should exercise caution
Semax
Evidence Level
Moderate human trials (Phase 1-2)
FDA Status
Research compound
Safety Overview
Semax has been used clinically in Russia for over 25 years with an excellent safety profile. It's approved there for treating stroke, cognitive impairment, and optic nerve diseases. Studies consistently show minimal side effects, mostly limited to mild nasal irritation when using the spray form. Unlike stimulants, Semax doesn't appear to cause tolerance, dependence, or withdrawal symptoms even with extended use.
Contraindications
- xPregnancy or planning to become pregnant
- xCurrently breastfeeding
- xHistory of seizures or epilepsy
- xKnown allergy to ACTH-related peptides
- xUncontrolled hypertension
