Dihexa vs GB-115
Comprehensive side-by-side comparison of mechanisms, dosing, side effects, and research
Also: N-hexanoic-Tyr-Ile-(6) aminohexanoic amide
A potent cognitive-enhancing peptide derived from angiotensin IV. Reported to be 10 million times more potent than BDNF at promoting synaptogenesis.
Also: Ranquilon, N-phenylacetyl-L-prolylglycine ethyl ester
A dipeptide anxiolytic and nootropic that acts as a CCK-1 (cholecystokinin) receptor antagonist. Developed in Russia with completed Phase 3 trials for anxiety. Users report significant improvements in focus, attention, and ADHD-like symptoms.
Key Comparison Insights
- Both peptides belong to the Cognitive category, suggesting similar primary applications.
- GB-115 has stronger research evidence (Human Trials) compared to Dihexa (Animal Studies).
Detailed Comparison
| Attribute | Dihexa | GB-115 |
|---|---|---|
| Category | Cognitive | Cognitive |
| FDA Status | Not FDA Approved | Not FDA Approved |
| Clinical Status | Pre I II III IV FDA | Pre I II III IV FDA |
| Mechanism of Action | Dihexa activates hepatocyte growth factor (HGF) signaling through the c-Met receptor. This promotes dendritic spine formation, enhances synaptic connections, and supports neuronal survival. Crosses blood-brain barrier orally. | GB-115 works by blocking central cholecystokinin-1 (CCK-1) receptors in the brain. CCK is involved in anxiety, panic responses, and cognitive modulation. By antagonizing these receptors, GB-115 reduces anxiety while improving attention, processing speed, and reaction time. It also modulates dopaminergic pathways involved in focus and motivation. |
| Common Dosing | 5-20 mg oral or sublingual daily Once daily, effects can last up to 10 days | 6 mg daily (2 mg three times daily) 2-3 times daily (morning, afternoon, evening) |
| Administration | Oral, sublingual, or intranasal | Oral tablets or sublingual |
| Typical Duration | Cycles of 2-4 weeks | 21+ days in clinical trials, effects noted by day 7 |
| Best Time to Take | Morning | Morning and throughout the day |
Possible Side Effects May vary by individual |
|
|
| Research Summary | Animal studies show remarkable cognitive enhancement and reversal of scopolamine-induced memory deficits. Research demonstrates increased dendritic spine density. Limited human data but significant interest in nootropic community. | Clinical studies in patients with Generalized Anxiety Disorder (GAD) showed GB-115 (6mg/day) significantly improved reaction time, attention, and processing speed within 7 days of treatment. A 21-day trial with 31 patients demonstrated anxiolytic effects comparable to benzodiazepines without sedation or dependency. Currently in Phase II/III trials (NCT05586789) for anxiety disorders. Anecdotal reports suggest benefits for ADHD symptoms, though direct ADHD trials are pending. |
Frequently Asked Questions: Dihexa vs GB-115
What is the difference between Dihexa and GB-115?
Dihexa is a cognitive peptide that a potent cognitive-enhancing peptide derived from angiotensin iv. reported to be 10 million times more potent than bdnf at promoting synaptogenesis. GB-115 is a cognitive peptide that a dipeptide anxiolytic and nootropic that acts as a cck-1 (cholecystokinin) receptor antagonist. developed in russia with completed phase 3 trials for anxiety. users report significant improvements in focus, attention, and adhd-like symptoms. The main differences lie in their mechanisms of action and clinical applications.
Which is better, Dihexa or GB-115?
Neither is universally "better" - the choice depends on your specific goals. Dihexa is typically used for cognitive purposes, while GB-115 is used for cognitive. Always consult with a healthcare provider to determine which may be appropriate for your situation.
Can Dihexa and GB-115 be used together?
Some peptide protocols combine multiple compounds for synergistic effects. However, using Dihexa and GB-115 together should only be considered under medical supervision, as both compounds have their own side effect profiles and potential interactions. Research on their combined use may be limited.
