Full L-Tryptophan profile (https://www.bodyhackguide.co/compound/l-tryptophan) ## Pinealon Pinealon is a synthetic tripeptide — glutamyl-aspartyl-arginine (Glu-Asp-Arg, or EDR) — developed by the St Petersburg Institute of Bioregulation and Gerontology (IBG) under the leadership of Professor Vladimir… **Lowest listed price:** $45.00 across 3 listings Full Pinealon profile (https://www.bodyhackguide.co/compound/pinealon) ## Side-by-side comparison | Attribute | L-Tryptophan | Pinealon | | --- | --- | --- | | Category | Nootropic | Nootropics | | Research Stage | Preclinical | Preclinical | | Mechanism of Action | L-Tryptophan acts primarily as the upstream precursor to serotonin, melatonin, and — via the dominant kynurenine pathway — NAD+ and a family of bioactive metabolites. Its pharmacology is metabolism-driven: tryptophan itself has no direct receptor binding of… | The proposed mechanism of Pinealon is rooted in the Khavinson school's broader theory of short-peptide tissue-specific bioregulation. The full theory is worth understanding because it underlies all twelve Russian bioregulator compounds in this catalog. The… | | Half-Life | — | Not formally characterized in humans. Short regulatory peptides of this class are cleared from plasma within minutes; the Khavinson framework proposes durable downstream gene-expression effects that outlast the brief dosing window, which is the stated rationale for pulsed cycling rather than continuous dosing. | | Typical Dose Range | — | Subcutaneous (primary route): 2-10 mg/day, typically 3-5 mg, in pulsed 10-20 day cycles, 2-4 cycles/year. Intranasal: 150-800 mcg per nostril daily. Research use only; oral dosing is not recommended because the peptide is largely degraded by GI proteases. | | Dosing Frequency | — | Once daily during a cycle (morning preferred); some advanced users split into AM + midday doses. Not dosed continuously year-round - cycles are pulsed. | | Administration | — | — | | Side Effects | L-Tryptophan has a generally favorable side effect profile at standard doses in quality-sourced product, but several considerations — particularly serotonin syndrome risk and the 1989 EMS legacy — warrant specific attention. Gastrointestinal effects — the most… | The side-effect profile of Pinealon, based on the available Russian clinical literature and user-reported experience, is described as mild and uncommon. Whether this reflects genuinely low toxicity or inadequate reporting in the available studies is a… | | Molecular Weight | — | 418.40 g/mol (C15H26N6O8) | | Common Vial Sizes | — | — | ## Price History 2 data points - Ion Peptide - Disguised Alpha ### L-Tryptophan: potential benefits - No structured benefit list published. ### Pinealon: potential benefits - Neuroprotection against oxidative and hypoxic stress (preclinical models) - Antioxidant support - reduced oxidative DNA damage in aged neurons (in vitro) - Cognitive and memory support in aging populations (small Russian clinical reports) - Reduced neuronal apoptosis and support of dendritic-tree integrity in cell models - Investigated for neuroprotection in Alzheimer's-model systems (preclinical) ## Frequently asked ### What's the difference between L-Tryptophan and Pinealon? L-Tryptophan is a nootropic that l-tryptophan acts primarily as the upstream precursor to serotonin, melatonin, and — via the dominant kynurenine pathway — nad+ and a family of bioactive metabolites. its…. Pinealon is a nootropics that the proposed mechanism of pinealon is rooted in the khavinson school's broader theory of short-peptide tissue-specific bioregulation. the full theory is worth understanding because…. The two differ in mechanism, half-life (not reported vs Not formally characterized in humans. Short regulatory peptides of this class are cleared from plasma within minutes; the Khavinson framework proposes durable downstream gene-expression effects that outlast the brief dosing window, which is the stated rationale for pulsed cycling rather than continuous dosing.), and typical dose range. ### Which has the longer half-life, L-Tryptophan or Pinealon? L-Tryptophan has a half-life of not reported. Pinealon has a half-life of Not formally characterized in humans. Short regulatory peptides of this class are cleared from plasma within minutes; the Khavinson framework proposes durable downstream gene-expression effects that outlast the brief dosing window, which is the stated rationale for pulsed cycling rather than continuous dosing.. Longer half-lives generally mean less frequent dosing but slower on/off kinetics. ### Can you stack L-Tryptophan and Pinealon? Stacking depends on mechanism overlap, safety profile, and goals. L-Tryptophan and Pinealon should only be stacked after reviewing each compound's individual protocol page, side effect profile, and any published interaction data.
