It is considered one of the most potent cognitive enhancers ever tested in animal models… **Lowest listed price:** $79.99 across 3 listings Full Dihexa profile (https://www.bodyhackguide.co/compound/dihexa) ## Side-by-side comparison | Attribute | Noopept + Choline Chloride Blend | Dihexa | | --- | --- | --- | | Category | Cognitive | Nootropics | | Research Stage | Blend has no clinical trials; component evidence ranges from preclinical (Noopept) to small human RCTs (choline sources). | Preclinical | | Mechanism of Action | This is a two-component nootropic stack, not a single molecule, so its rationale comes from the mechanisms of its parts rather than from any studied 'blend.' Noopept (N-phenylacetyl-L-prolylglycine ethyl ester) is a proline-containing dipeptide designed as an… | Dihexa is a small-molecule analog derived from angiotensin IV (AngIV). It retains the Tyr-Ile core of Nle1-AngIV, with an N-terminal hexanoic acid cap and a C-terminal 6-aminohexanoic amide that give it metabolic stability and blood-brain-barrier penetration.… | | Half-Life | Not a single-molecule value - this is a two-component stack. Noopept has a short plasma half-life, with central effects that outlast blood levels; the rise in brain choline from alpha-GPC or CDP-choline persists for several hours. | Not characterized in humans. Dihexa was engineered for metabolic stability (resistant to plasma and enzymatic degradation) and blood-brain-barrier penetration; in preclinical work its central procognitive effects appear to outlast its plasma presence. | | Typical Dose Range | Noopept 10-30 mg (10,000-30,000 mcg)/day; choline source 150-600 mg/day (alpha-GPC) or 250-500 mg/day (CDP-choline). The blend has no validated dosing - ranges are extrapolated from single-component use. | 5 to 40 mg oral per day (anecdotal range; no established human dose) | | Dosing Frequency | 1-3 times daily for Noopept; the choline source is usually taken 1-2 times daily alongside it. | Once daily (oral), typically in the morning | | Administration | — | Oral, Intranasal, Subcutaneous | | Side Effects | Most reported effects are mild and dose-related. Noopept: headache (often a sign of too little OR too much choline), irritability, restlessness, fatigue, and sleep disturbance if taken late in the day. Choline sources: headache, nausea, GI upset, and - at… | No controlled human safety data. Anecdotal user reports include headache, fatigue, irritability or anxiety, insomnia, and vivid dreams, usually at higher doses. The most serious concern is theoretical rather than reported: because dihexa acts on the HGF/c-Met… | | Molecular Weight | — | 504.7 g/mol | | Common Vial Sizes | — | 50mg, 100mg | ## Price tracking Tracking Dihexa prices since September 5, 2026. Trend chart unlocks once we have price snapshots from more than one day. ### Noopept + Choline Chloride Blend: potential benefits - Reported (anecdotal) day-to-day gains in focus, verbal fluency, and working memory - from user reports, not from trials of this blend - Choline is added mainly to reduce the racetam-type headache some users get from Noopept taken without enough choline - Noopept shows memory-supporting and neuroprotective effects in animal models of cognitive impairment [PMID:25096780][PMID:17092975] - CDP-choline (citicoline) improved episodic and composite memory vs placebo in a 12-week RCT in healthy older adults with age-associated memory impairment [PMID:33978188] - Alpha-GPC and CDP-choline act as acetylcholine precursors, raising brain choline availability [PMID:1662399] - Component evidence is strongest for the choline sources; the blend as a whole has no clinical trials ### Dihexa: potential benefits - Synaptogenesis: formation of new dendritic spines and functional synapses (preclinical) - Memory and spatial-learning support in rodent models - Potential research application in Alzheimer's and other neurodegenerative disease models - HGF/c-Met and PI3K/Akt-linked neuroplasticity (mechanism proposed; key paper retracted) ## Frequently asked ### What's the difference between Noopept + Choline Chloride Blend and Dihexa? Noopept + Choline Chloride Blend is a cognitive that this is a two-component nootropic stack, not a single molecule, so its rationale comes from the mechanisms of its parts rather than from any studied 'blend.' noopept…. Dihexa is a nootropics that dihexa is a small-molecule analog derived from angiotensin iv (angiv). it retains the tyr-ile core of nle1-angiv, with an n-terminal hexanoic acid cap and a c-terminal…. The two differ in mechanism, half-life (Not a single-molecule value - this is a two-component stack. Noopept has a short plasma half-life, with central effects that outlast blood levels; the rise in brain choline from alpha-GPC or CDP-choline persists for several hours. vs Not characterized in humans. Dihexa was engineered for metabolic stability (resistant to plasma and enzymatic degradation) and blood-brain-barrier penetration; in preclinical work its central procognitive effects appear to outlast its plasma presence.), and typical dose range. ### Which has the longer half-life, Noopept + Choline Chloride Blend or Dihexa? Noopept + Choline Chloride Blend has a half-life of Not a single-molecule value - this is a two-component stack. Noopept has a short plasma half-life, with central effects that outlast blood levels; the rise in brain choline from alpha-GPC or CDP-choline persists for several hours.. Dihexa has a half-life of Not characterized in humans. Dihexa was engineered for metabolic stability (resistant to plasma and enzymatic degradation) and blood-brain-barrier penetration; in preclinical work its central procognitive effects appear to outlast its plasma presence.. Longer half-lives generally mean less frequent dosing but slower on/off kinetics. ### Can you stack Noopept + Choline Chloride Blend and Dihexa? Stacking depends on mechanism overlap, safety profile, and goals. Noopept + Choline Chloride Blend and Dihexa should only be stacked after reviewing each compound's individual protocol page, side effect profile, and any published interaction data.
