Understand this compound
What is Dihexa?
Preclinical / animal onlyA lab-made molecule studied for its striking ability, in animal brains, to encourage neurons to form new connections. Of interest for memory and brain-aging research; almost no human data exist.
Good to know: Extremely limited human safety data exist despite its high reported preclinical potency; oral bioavailability and long-term effects in humans are unestablished.
How does Dihexa work?
The science
An angiotensin IV-derived peptide that potentiates hepatocyte growth factor (HGF) activity at the c-Met receptor, driving synaptogenesis and dendritic spine formation.
Mechanism of action from published research — how the molecule behaves, not a claim about any product or any human-use effect.
What is Dihexa researched for?
Studied for cognitive enhancement and neurodegenerative disease via promotion of new synapse formation.
- Cognitive & moodStudied in memory, focus, mood, and neuroprotection research.
How far has the research gone?
Preclinical / animal research — potent synaptogenic effects shown in rodent models, with essentially no published human clinical data.
Where the science stands — an approved drug is not the same as the research-grade material a vendor sells, which is unregulated regardless.
What should I check before buying?
- Independent purity. Look for a third-party COA (Janoshik or MZ) showing a measured purity — not just a number the vendor typed.
- Batch match. The strongest evidence is a certificate for the exact batch you’ll receive, attributed to this vendor — check the cross-verification on the listing.
- Vendor reputation. See how the vendor is talked about in the community before trusting a new name.
Research context only — VialGrade never gives dosing, medical, or human-use guidance.

Compare by real cost
Every Dihexa listing, cheapest per mg first
Sticker prices hide the size, so listings are ranked by what a milligram actually costs — with independently tested purity where it exists. All 14 are here: the last 4 are listings whose vendor never published a strength we can read, so they have no per-mg figure to sort on.

Real $/active mg divides the price-per-mg by the measured purity — the honest cost of the actual peptide, so a 90%-pure vial isn’t compared as if it were 99%. Too cheap? flags a listing far below the market rate — often underdosing or a fake, not a deal. The crown marks the cheapest non-outlier; best value marks the lowest real cost per active mg. A vendor shown as Unavailable or Low stock is priced here but not currently buyable.
What the research says
Scientific evidence & regulatory status
What the published literature actually shows about Dihexa — separate from any vendor’s marketing. Each finding links to its paper. This is education, not medical or dosing advice.
Regulatory status
No FDA-approved drug
Not FDA-approved. FDA placed dihexa acetate in category 2 (significant safety risks) for pharmacy compounding, stating it had identified no human exposure data for any route of administration; the nomination was later withdrawn, so it appears on no FDA bulks list.
Research-use-only — not FDA-approved
Sold “for research use only,” this compound is not FDA-approved for human use and has not been evaluated for safety, purity, or sterility in people. It is generally not a scheduled controlled substance, so buying it as a research chemical is typically not itself a drug crime — but marketing or using it as a drug is not lawful, and it is not a dietary supplement.
General information, not legal or medical advice. VialGrade sells nothing and encourages no human use.
Research notes aren’t product proof
Research summaries describe published literature and market data only. They do not establish the identity, quality, safety, or legal status of any listed physical product.
