What Octreotide is
Native somatostatin is cleared from the body within minutes. Octreotide keeps the core of the active region but adds D-amino acids and a terminal amino-alcohol, which makes it far more stable.
In research it is used to study somatostatin receptors, especially subtypes 2 and 5, and the hormone-release pathways they regulate. Its cyclic structure is held together by a disulfide bond.
What the research literature studies
- Binding profile across the five somatostatin receptor subtypes
- Inhibition of hormone release in cell and tissue models
- Stability gains from D-amino acids and a cyclic scaffold
Evidence rating: 5/5
Approved drug, phase 3 trials. Approved medicine with decades of clinical use in its authorised indications. See our methodology for how levels are assigned.
- Most outcome data come from the branded medicine, not from research-grade material.
- Receptor-subtype selectivity measured in vitro is a simplification of what happens in tissue.
Regulatory status
Octreotide is authorised as a prescription medicine by the MHRA, EMA and FDA under brand names. Laboratory research material is not that medicine and must not be used in people or animals.

Octreotide FAQ
Why is octreotide only eight amino acids?
It keeps only the short segment of somatostatin that drives receptor binding, which is enough for activity and makes the molecule easier to stabilise.
What holds octreotide's ring together?
A disulfide bond between two cysteine residues.
Where can I buy Octreotide for research?
Nordapep does not currently list Octreotide. You can ask Nordapep about availability, or compare related compounds that are in stock.
Is Octreotide approved?
Octreotide is authorised as a prescription medicine by the MHRA, EMA and FDA under brand names. Laboratory research material is not that medicine and must not be used in people or animals.
