Dihexa

Dihexa is a synthetic oligopeptide derived from angiotensin IV that potently enhances cognitive function by promoting synaptogenesis. Originally developed at Washington State University for Alzheimer's disease, it's 7 orders of magnitude more potent than BDNF at stimulating new synaptic connections and uniquely crosses the blood-brain barrier.

• Memory Enhancement
• Learning Acceleration
• Cognitive Recovery

Dramatic synaptogenesis promotion, cognitive enhancement, memory improvement, neuroprotection, potential neuroregeneration. May help with Alzheimer's, TBI, and age-related cognitive decline.

Dihexa binds to hepatocyte growth factor (HGF) with high affinity and potentiates its activity at c-Met receptor, activating PI3K/AKT pathways. This promotes formation of new synaptic connections at levels 10 million times more potent than BDNF. Crosses blood-brain barrier effectively via oral or injectable routes.

Peak plasma concentration: 2 hrs. Elimination half-life: 12 hrs. Largely cleared by: ~2.5 days.

Research protocols from published literature — not dosing recommendations.

• Semax — Compatible: Can be stacked for enhanced cognitive benefits but requires careful cycling to avoid overstimulation
• Selank — Compatible: Synergistic cognitive and anxiolytic effects when combined, but monitor for neural overstimulation
• BPC-157 — Compatible: No known negative interactions - different mechanisms of action
• P21 — Use Caution: Both affect neuroplasticity strongly - avoid concurrent use without careful cycling
• Noopept — Compatible: Some users stack for cognitive enhancement but limited safety data on combination
• NAD+ — Compatible: Complementary mechanisms - NAD+ supports cellular energy while Dihexa promotes synaptogenesis
• Cerebrolysin — Use Caution: Both are potent neurotrophic agents - combining may lead to excessive stimulation
• TB-500 — Compatible: No known interactions - TB-500 focuses on tissue repair while Dihexa targets neural connections

Supplies:

• Pharmaceutical-grade DMSO (dimethyl sulfoxide) — required because Dihexa does not dissolve in water. DMSO is a common lab solvent used in FDA-approved injectables and is safe at these small volumes. Do NOT use industrial-grade DMSO.
• PEG300 (polyethylene glycol 300) — used to dilute the DMSO concentrate into an injectable solution
• Tween 80 (polysorbate 80) — helps keep the solution stable and well-mixed
• Sterile saline (0.9% NaCl) for final dilution
• Insulin syringes (for SubQ)
• Alcohol swabs
• Sterile vial

1. 1Dihexa does not dissolve in water or ethanol — you must use DMSO as the solvent
2. 2For a 10mg vial: add 100 µL (0.1 mL) of pharmaceutical-grade DMSO to dissolve the powder completely
3. 3Add 400 µL (0.4 mL) PEG300 and gently swirl until the solution is clear
4. 4Add 50 µL (0.05 mL) Tween 80 and gently swirl until clear
5. 5Add 450 µL (0.45 mL) sterile saline and gently swirl until clear — this gives you 1 mL total at 10 mg/mL
6. 6The final ratio is 10% DMSO / 40% PEG300 / 5% Tween 80 / 45% saline — always add solvents in this order and make sure the solution is clear before adding the next one
7. 7Store at 2-8°C, protected from moisture. Use within 30 days. Avoid repeated freeze-thaw cycles.
8. 8For oral: No reconstitution needed — use capsules as provided

Week 1-2: Subtle cognitive changes, possible headaches. Week 2-4: Improved focus and memory formation. Week 4-8: Peak cognitive benefits, enhanced learning. Post-cycle: Effects may persist for days to weeks. Common effects: Mental clarity, faster learning. Side effects: Headaches (most common), anxiety, sleep disruption if taken late.

Not FDA approved - research compound only. Theoretical cancer risk via c-Met activation. No long-term human safety data available. Avoid if history of cancer. Not for pregnant/nursing women. May cause overstimulation or anxiety. Requires cycling to prevent tolerance.

Dihexa should be stored at Oral capsules: room temperature. Injectable: requires DMSO to dissolve (Dihexa won't dissolve in water), store DMSO stock solution at 2-8°C. Always use pharmaceutical-grade DMSO..
