320cbe4ef2 · Deep dive: Pinealon (PEPTIDES.md Section 4.3, Tier 4 — Avoid) — replaces previously lumped mention within Khavinson section with full ~219-line analysis. Discovery: Khavinson group St Petersburg, Glu-Asp-Arg tripeptide as cytogen subset. Proposed Khavinson mechanism (site-directed DNA binding to promoter regions, cell-penetration, transcription factor mimicry, organ-specific gene regulation). Information-theoretic objection as central critique: 3-mer = ~13 bits sequence info vs ~31.5 bits needed for unique site in 3 Gb genome — gap is intrinsic. Three additional convergent biophysics objections: serum peptidase kinetics, absent CPP structural motifs, no ITC/SPR confirmation. Animal evidence covered (Khavinson rodent studies on cognition/ischemia/aging). Human evidence gap (only small unblinded Russian trials). Twitter/social media promotion concern noted honestly. Sourcing concerns (Russian vendors, unverifiable purity). Safety profile (limited Khavinson tox only). Genotype interactions (APOE ε4, DIO2 het, CLOCK CC). Evidence summary table 8 claims. 14 references. Framework alignment: Tier 4 on mechanism implausibility AS CLAIMED + evidence quality grounds. Not claiming biologically inert — door left open for downstream effect via free amino acids or NO-substrate Arg. §4.2 Khavinson reframed as broader methodological critique. GLP-1 cross-ref bumped 4.3 → 4.4. File 734 → 963 lines. · Updated 2026-05-24 03:29:47 +00:00
