What is Larazotide?
Larazotide is an octapeptide investigated for celiac disease and intestinal-barrier dysfunction. It is most often studied as an oral formulation; injectable use is uncommon and reference doses here are illustrative only.
| 5 mg | lyophilized powder |
| 0.5 mg | ≈ 20 U-100 units (at 5mg / 2mL) |
| 1 mg | ≈ 40 U-100 units (at 5mg / 2mL) |
How it's typically prepared
Larazotide is most often delivered orally. Reconstitution math may not apply to your formulation.
