Dihexa vs Octreotide
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Dihexa
Dihexa is a nootropic peptide derived from angiotensin IV. It has shown remarkable cognitive-enhancing properties in animal studies, being described as potentially millions of times more potent than BDNF.
Full details →Octreotide
Octreotide (Sandostatin) is a synthetic somatostatin analog FDA-approved for acromegaly, carcinoid tumors, and VIPomas. It inhibits growth hormone and various GI hormones.

| Aspect | Dihexa | Octreotide |
|---|---|---|
| Mechanism | Acts as a hepatocyte growth factor (HGF) potentiator by binding to its receptor c-Met. Promotes synaptogenesis, neuronal survival, and cognitive enhancement through this pathway. | Binds to somatostatin receptors (primarily SSTR2 and SSTR5) to inhibit GH, glucagon, insulin, and gastric secretions. Reduces blood flow to GI tract and inhibits tumor hormone secretion. |
| Typical Dosage | Research dosing is highly variable due to extreme potency. Typical range: 10-40mg orally or sublingually. Start with lowest doses due to potency. | Varies by indication. Acromegaly: 50-100mcg three times daily initially, up to 500mcg TID. LAR (long-acting): 20-30mg IM every 4 weeks. |
| Administration | Can be taken orally, sublingually, or intranasally. Extremely potent - careful dosing is essential. Best used cyclically. | Subcutaneous injection for immediate-release (between meals). Intramuscular for LAR depot form. Requires monitoring of gallbladder, glucose, and thyroid. |
| Side Effects | Limited human data. Reported effects include headache, temporary brain fog during adjustment, and potential mood changes. | GI effects (diarrhea, nausea, abdominal pain), gallstones (up to 25% of long-term users), injection site reactions, and blood glucose changes. |
