Dihexa Dosage Guide: Protocols, Calculator & Safety
Everything you need to know about Dihexa dosing — protocols, safety, and where to buy.
Dose Range
5 to 40 mg oral per day (anecdotal range; no established human dose)
Frequency
Once daily (oral), typically in the morning
Cycle Length
2 to 4 weeks on with a break between cycles; highly experimental, no established cycle length
Half-Life
Not characterized in humans. Dihexa was engineered for metabolic stability (resistant to plasma and enzymatic degradation) and blood-brain-barrier penetration; in preclinical work its central procognitive effects appear to outlast its plasma presence.

Dosing Protocols
Research use only; no established human dose. Anecdotal starting protocol: 5 to 10 mg once daily, oral, for 2 to 4 weeks. Begin at the low end to assess tolerance. There is no controlled human safety data.
Anecdotal only: 10 to 20 mg once daily, oral, in short cycles of up to about 4 weeks with breaks. Not evidence-based; no human trials support any dose.
Upper anecdotal range: 20 to 40 mg once daily, oral, for up to about 4 weeks followed by a break. No safety data supports doses this high or chronic use, and the theoretical HGF/c-Met oncogenic concern rises with cumulative exposure.
Weight-Based Dosing
Commonly Stacked With
Some researchers use alongside NSI-189 for synergistic neurogenic effects. Given the cancer concern, this is a compound to approach with significant caution and personal risk assessment.
Side Effects & Safety
Contraindications
Active cancer or a personal history of cancer (HGF/c-Met is an oncogenic pathway); do not use without oncologist oversight. Pregnancy or breastfeeding. History of seizures. Active neurodegenerative disease (unstudied interaction). Concurrent use of other potent nootropics without careful titration. When in doubt, do not use; there is no human safety data.
Additional Notes
HIGHLY EXPERIMENTAL. No human dosing or safety data exists; all figures are anecdotal. Dihexa is orally active, so oral is the primary anecdotal route. Foremost concern: the HGF/c-Met pathway it targets is implicated in tumor growth and metastasis, so cumulative or long-term exposure carries a theoretical cancer risk. Not recommended without a thorough personal risk assessment and, ideally, clinician oversight.

Frequently Asked Questions
What is the recommended Dihexa dosage?
The typical dose range for Dihexa is 5 to 40 mg oral per day (anecdotal range; no established human dose). It is usually administered Once daily (oral), typically in the morning. Always start with the lowest effective dose.
How often should I take Dihexa?
Once daily (oral), typically in the morning
Does Dihexa need to be cycled?
Yes, typical cycle length is 2 to 4 weeks on with a break between cycles; highly experimental, no established cycle length.
What are Dihexa side effects?
No controlled human safety data. Anecdotal user reports include headache, fatigue, irritability or anxiety, insomnia, and vivid dreams, usually at higher doses. The most serious concern is theoretical rather than reported: because dihexa acts on the HGF/c-Met pathway, a driver of tumor growth and metastasis, its long-term effects are unknown.
