The full theory is worth understanding because it underlies all twelve Russian bioregulator compounds in this catalog. The… | Cortagen is a synthetic tetrapeptide, Ala-Glu-Asp-Pro (AEDP), created by the Khavinson group through directed synthesis based on the amino-acid composition of Cortexin, a polypeptide complex extracted from the cerebral cortex [PMID:15159690]. It is a… | | 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. | Unknown (tetrapeptide; estimated <4 hours) | | 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. | once_daily | | Administration | — | Subcutaneous, Intramuscular | | Side Effects | 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) | 430.4 g/mol (C17H26N4O9, PubChem CID 18439621) | | Common Vial Sizes | — | 20 | ## Price History 2 data points - Ion Peptide - Disguised Alpha ## Price tracking Tracking Cortagen prices since April 22, 2026.

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…. Cortagen is a longevity that cortagen is a synthetic tetrapeptide, ala-glu-asp-pro (aedp), created by the khavinson group through directed synthesis based on the amino-acid composition of cortexin, a…. The two differ in mechanism, 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. vs Unknown (tetrapeptide; estimated <4 hours)), and typical dose range. ### Which has the longer half-life, Pinealon or Cortagen? 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.. Cortagen has a half-life of Unknown (tetrapeptide; estimated <4 hours). Longer half-lives generally mean less frequent dosing but slower on/off kinetics. ### Which is cheaper, Pinealon or Cortagen? Lowest listed price on BodyHackGuide: Pinealon from $45.00, Cortagen from $79.00. Prices are pulled from the vendor listings tracked on BHG and change frequently. See the compare tables on each compound page for the current set of offers. ### Can you stack Pinealon and Cortagen? Stacking depends on mechanism overlap, safety profile, and goals. Pinealon and Cortagen should only be stacked after reviewing each compound's individual protocol page, side effect profile, and any published interaction data.
