- Documented dose
- 5–20 mg
- Typical frequency
- Once daily, or split into 2-3 doses
- Cycle
- 10 weeks on, 5 off
- Half-life
- Long relative to most peptides
- Regulatory status
- Research chemical — not approved for human use.
No syringe needed
Dihexa is taken oral capsule or tablet, so there is no U-100 syringe draw for it.
What it does
Dihexa is used by people looking for a strong, long-lasting cognitive effect — better memory formation, faster learning, and clearer thinking. It is taken as a capsule, usually in the morning on an empty stomach, in 8-12 week blocks.
Mechanism
Boosts hepatocyte growth factor (HGF) signalling at the c-Met receptor, which drives the formation of new synapses.
Storage — lyophilisedwhat's this?
Store capsules cool and dry.
Storage — reconstitutedwhat's this?
Not applicable — oral capsules.
Reconstitution noteswhat's this?
No mixing needed. 1-4 capsules (5-20 mg) per day, taken on an empty stomach 30 minutes before food. Morning dosing avoids sleep disruption.
Stacks well with
- SemaxSynapse growth plus immediate focus and clarity.
- PinealonTwo different brain-repair mechanisms in one course.
Popular combinations reported in the community and research literature — not a recommendation. Adding peptides multiplies side-effect risk; check with a clinician.
Commonly reported side effects
- Sleep disturbance if dosed late
- Headache
- Overstimulation
Contraindications noted
- Any active cancer — synapse-growth signalling is not selective
Research notes
Animal work is striking, but there is no published human trial. The growth-factor mechanism is the main reason for caution.
