Dihexa

Cognitive · Mood Nasal Spray

Dihexa is a small-molecule peptide derived from angiotensin IV, designed to cross the blood–brain barrier and dramatically enhance synaptogenesis — the formation of new neural connections. Early research suggests it's among the most potent BDNF-style cognitive support agents available, with applications in memory, learning, and neurodegenerative concerns.

Best for: Significant cognitive decline, post-concussion / TBI rebuild, advanced longevity protocols, age-related memory complaints.

Frequently Asked

What clients want to know about Dihexa

The questions, answered.

Enhances synaptogenesis — formation of new connections between neurons.
Profound memory and learning support in animal and early human research.
Crosses the blood–brain barrier with high bioavailability via nasal route.
Neuroprotective against age-related and injury-related neuron loss.
Investigational support for Alzheimer's-adjacent cognitive concerns.
Often paired with Semax or Pinealon for layered cognitive protocols.

Hepatocyte growth factor (HGF) augmentation: drives the c-Met pathway responsible for synapse formation.
Synaptogenesis: measurable increase in new dendritic spines in preclinical work.
BBB penetration: small molecular size enables direct CNS delivery via nasal mucosa.
Neuroprotective signaling against age-related neuron loss.

Weeks 1–2: Subtle improvements in word recall and learning speed — often noticed by spouses first.
Weeks 4–6: Clear gains in working memory and mental stamina; cognitive tasks feel less effortful.
Weeks 8–12: Durable cognitive improvement; many clients consolidate with a maintenance protocol.

Mild nasal irritation at the spray site.
Transient headache in the first few days.
Vivid dreams or sleep changes if dosed late in the day.
Light-headedness in sensitive individuals.

Dose in the morning to avoid sleep disruption.
Start at the low end and titrate up under provider guidance.
Pair with mentally engaging work — Dihexa works best when paired with learning demands.
Use within an integrated cognitive protocol rather than as a standalone supplement.

Pregnancy or breastfeeding.
Active brain malignancy without oncology oversight.
Severe hypertension — discuss angiotensin pathway interactions with your provider.
Known peptide hypersensitivity.

Important Note The FDA's position on peptides continues to evolve. Availability of specific compounds may change, and not all peptides discussed are currently offered at every visit. Book a consultation with our provider team to discuss your goals, current options, and what's appropriate for you.
