The peptide library
Every entry states its evidence level and approval status up front. Filter by what the research shows, not by what a product page claims.
Cosyntropin (tetracosactide)
The active first 24 amino acids of ACTH, licensed mainly as the standard test for adrenal function.
Desmopressin
A long-acting vasopressin analogue approved for central diabetes insipidus, bedwetting and mild bleeding disorders.
Glucagon
The pancreatic hormone that raises blood glucose, licensed as emergency treatment for severe hypoglycaemia.
Insulin glargine
A long-acting insulin analogue that provides a flat basal insulin level over roughly 24 hours.
Lanreotide
A long-acting somatostatin analogue approved for acromegaly and gastroenteropancreatic neuroendocrine tumours.
Mecasermin
Recombinant IGF-1, licensed for the rare children whose growth failure comes from an IGF-1 deficiency that growth hormone cannot fix.
Octreotide
The first synthetic somatostatin analogue, approved for acromegaly, neuroendocrine tumours and variceal bleeding.
Salmon calcitonin
A fish-derived hormone that slows bone breakdown, still used for Paget's disease and cancer-related high calcium. Its osteoporosis use was withdrawn in Europe over a cancer signal.
Teriparatide
The active fragment of human parathyroid hormone, used as the main bone-building treatment for severe osteoporosis. Strong evidence, and a good example of dose timing changing a drug's entire effect.
Terlipressin
A slow-release vasopressin analogue licensed for hepatorenal syndrome and bleeding oesophageal varices.
