Evidence Anchor
BioHarmony 4.4/10
Dihexa is a 4.4 / 10 fit for experimenters looking at cognition through a high-risk research-chemical lens, not people who want a normal nootropic, not a clinically proven memory drug. The cleanest evidence anchors are [McCoy 2013](https://pubmed.ncbi.nlm.nih.gov/23055539/), which supports rodent and cell procognitive activity, and [Sun 2021](https://pubmed.ncbi.nlm.nih.gov/34827486/), which reported APP/PS1 mouse memory rescue. [FDA 2026](https://www.fda.gov/drugs/human-drug-compounding/certain-bulk-drug-substances-use-compounding-may-present-significant-safety-risks) adds useful context: states human exposure data and key safety information are lacking. The practical gap is the same one that shows up across the report: mechanism and early outcomes are more convincing than broad real-world certainty. In practice, Dihexa belongs after the basics, works best when the target is specific, and deserves tracking around benefits, side effects, interactions, and cost before it becomes a standing protocol. ✅ Best for: Researchers and informed self-experimenters specifically studying neurodegenerative mechanisms, not general productivity seekers. The least-unreasonable use case would be a short, carefully documented cycle in someone with a specific cognitive or neurodegenerative hypothesis, medical oversight, third-party identity and purity testing, no cancer risk factors, no competitive-sport constraints, no pregnancy or pediatric exposure, and no prescription-medication complexity. Even then, dihexa is better framed as a research-risk decision than a supplement recommendation. ❌ Avoid if: You have any personal cancer history, strong family cancer predisposition, pregnancy, lactation, pediatric exposure, cardiovascular disease, active unexplained symptoms, or current prescription medications. Avoid dihexa if you compete in drug-tested sport because WADA's 2026 list covers HGF and growth-factor modulators even though dihexa is not named. Also avoid it if you want a normal nootropic stack. The evidence base is preclinical, dosing is unvalidated, sourcing is gray-market, and the safety downside is too large for casual use. Sourcing & dosing caveat: gray-market supply; score assumes clean, correctly-dosed material.

My score and my verdict: one signal of three, never the whole answer.
Momentum
Signals begin with Edition 2
Direction needs two weekly snapshots to compare, so the arrows stay off until the next edition. Attention tracking is already running.
Momentum = how fast attention is rising across search, Reddit, PubMed, podcasts, and curated industry newsletters this week; it can flag an item as Overhyped/Fading, but it never overrides the evidence behind Proven. How momentum works.
