At a Glance Dose Range Noopept (Omberacetam) 10–30 mg Semax 200–900 mcg Frequency Multiple times daily Once daily Administration Oral (tablet/capsule) Intranasal spray Cycle Length 12+ weeks 4-6 weeks Onset Speed Rapid (hours to days) Evidence Level Limited human trials Moderate human trials (Phase 1-2) Efficacy Memory & Learning Brain Protection Mental Clarity Cognitive Enhancement Neuroprotection Mental Energy Technical Data Molecular Formula C17H22N2O4 Molecular Weight 318.4 g/mol Half-Life Short plasma half-life (minutes); rapidly converted to active metabolite cycloprolylglycine which has a longer pharmacological duration; effects persist for hours after dosing Bioavailability Orally bioavailable with BBB penetration; metabolized to active cycloprolylglycine; approximately 1000-fold more potent than parent compound piracetam CAS Number 157115-85-0 C37H51N9O10S 813.9 g/mol Several minutes to hours (intranasal effects persist longer) High via intranasal route (directly reaches brain) 80714-61-0 Protocols standard 10 mg twice daily (20 mg/day) Twice daily (morning and afternoon) 56 days (8 weeks) per clinical study Dose used in a controlled human study of mild cognitive impairment, improving cognition with good tolerability [6]. starting 250-500 mcg/day Once or twice daily 1-2 weeks Cognitive/nootropic practice with the 0.1% solution; downstream BDNF/NGF effects persist 12-24 h so dosing is once to twice daily [1][2]. 500-900 mcg/day Divided 2-3 times daily 3-4 weeks Mid-range nootropic practice dose; upregulates hippocampal BDNF/TrkB in animal models [1][2][3]. Applications Cognitive enhancement for learning, memory formation, and information retrieval Noopept (Omberacetam) is particularly well-suited for individuals focused on cognitive enhancement for learning, memory formation, and information retrieval. Research and clinical experience suggest meaningful benefits in this area when used as part of a comprehensive treatment approach. Neuroprotection against oxidative stress and age-related cognitive decline Noopept (Omberacetam) is particularly well-suited for individuals focused on neuroprotection against oxidative stress and age-related cognitive decline. Research and clinical experience suggest meaningful benefits in this area when used as part of a comprehensive treatment approach. Nootropic stacking — complements racetams, cholinergics, and neurotrophic peptides through distinct mechanisms Noopept (Omberacetam) is particularly well-suited for individuals focused on nootropic stacking — complements racetams, cholinergics, and neurotrophic peptides through distinct mechanisms. Research and clinical experience suggest meaningful benefits in this area when used as part of a comprehensive treatment approach. Support during periods of intense intellectual work or study Noopept (Omberacetam) is particularly well-suited for individuals focused on support during periods of intense intellectual work or study. Research and clinical experience suggest meaningful benefits in this area when used as part of a comprehensive treatment approach. 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 Profile Common Headache Irritability or restlessness Sleep disturbance Mild gastrointestinal discomfort Vivid dreams Uncommon Blood pressure increase Serious Allergic reaction Nasal irritation Mild headache Increased alertness Temporary blood pressure increase Dizziness Research Status FDA Status Research compound Safety Overview Noopept demonstrates excellent safety in Russian clinical trials with LD50 >2000 mg/kg (oral, rats)—approximately 100 times higher than therapeutic doses. No serious adverse events reported in human studies up to 30 mg/day for 6-12 weeks. Mild side effects (headache, irritability) occur in <5% of users and resolve with dose reduction. No carcinogenicity, mutagenicity, or teratogenicity in preclinical testing; minimal drug interactions due to lack of hepatic CYP450 metabolism. Contraindications xKnown hypersensitivity to Noopept, piracetam, or other racetam-class compounds xPregnancy and breastfeeding — insufficient safety data xSevere hepatic impairment — Noopept undergoes hepatic metabolism xSevere renal impairment — metabolites are renally excreted xLactose intolerance (some tablet formulations contain lactose as excipient) 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. xPregnancy or planning to become pregnant xCurrently breastfeeding xHistory of seizures or epilepsy xKnown allergy to ACTH-related peptides xUncontrolled hypertension Decision Guide Choose Noopept (Omberacetam) if...
