Dihexa vs GB-115

Comprehensive side-by-side comparison of mechanisms, dosing, side effects, and research

Dihexa

Also: N-hexanoic-Tyr-Ile-(6) aminohexanoic amide

Preclinical

A potent cognitive-enhancing peptide derived from angiotensin IV. Reported to be 10 million times more potent than BDNF at promoting synaptogenesis.

CognitiveAnimal Studies
GB-115

Also: Ranquilon, N-phenylacetyl-L-prolylglycine ethyl ester

Clinical Trials

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.

CognitiveHuman Trials

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).

Mechanism of ActionDihexa 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.

Research SummaryAnimal 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.
