    Alpha-GPC

    Alpha-GPC (chemical name L-alpha-glycerylphosphorylcholine; pharmaceutical name choline alfoscerate) is a naturally occurring cholinergic compound that serves as a highly bioavailable precursor to both acetylcholine (the…

    Dihexa

    Dihexa is a synthetic peptide analogue of the angiotensin IV metabolite LVV-hemorphin-7, developed at Washington State University. It is considered one of the most potent cognitive enhancers ever tested in animal models…

    Side-by-side comparison

    Attribute Alpha-GPC Dihexa
    Category Nootropic Nootropics
    Research Stage Preclinical Preclinical
    Mechanism of Action Alpha-GPC exerts its cognitive and performance-improving effects through several interconnected mechanisms centered on the cholinergic system and membrane phospholipid metabolism. Understanding these mechanisms clarifies both Alpha-GPC's appropriate use cases… 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 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 — 5 to 40 mg oral per day (anecdotal range; no established human dose)
    Dosing Frequency — Once daily (oral), typically in the morning
    Administration — Oral, Intranasal, Subcutaneous
    Side Effects Alpha-GPC is generally well-tolerated at typical supplemental doses (300-1200mg/day), with most side effects being mild, dose-dependent, and self-limiting. A minority of users experience more significant cholinergic sensitivity reactions that warrant dose… 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 257.22 g/mol 504.7 g/mol
    Common Vial Sizes — 50mg, 100mg

    Frequently asked

    What's the difference between Alpha-GPC and Dihexa?

    Alpha-GPC is a nootropic that alpha-gpc exerts its cognitive and performance-improving effects through several interconnected mechanisms centered on the cholinergic system and membrane phospholipid metabolism.…. 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 reported 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, Alpha-GPC or Dihexa?

    Alpha-GPC has a half-life of not reported. 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 Alpha-GPC and Dihexa?

    Stacking depends on mechanism overlap, safety profile, and goals. Alpha-GPC and Dihexa should only be stacked after reviewing each compound's individual protocol page, side effect profile, and any published interaction data. Use the BodyHackGuide stack builder for a structured review before combining research compounds.
