Sincalide
Sincalide activates CCK receptors, triggering gallbladder contraction and pancreatic enzyme secretion. This effect is used diagnostically to measure the gallbladder ejection fraction (e.g. in HIDA scintigraphy).
Teriparatid
Teriparatide corresponds to the biologically active first 34 amino acids of human parathyroid hormone and binds the PTH-1 receptor on bone and kidney cells. The literature describes that intermittent receptor activation preferentially stimulates the activity of bone-forming osteoblasts, whereas continuously elevated PTH exposure (as in hyperparathyroidism) tends to favor bone resorption. This time-dependent difference is regarded as the mechanistic basis for the bone-anabolic effect observed in studies.

Frequently asked questions
- What is the difference between Sincalide and Teriparatid?
- Sincalide is classified as "Исследования (прочее)", while Teriparatid is classified as "Исследования (прочее)". Sincalide: Sincalide is the synthetic C-terminal octapeptide of the hormone cholecystokinin (CCK-8). As Kinevac it is FDA-approved to stimulate gallbladder contraction for diagnostic imaging. Teriparatid: Teriparatide is the recombinant N-terminal fragment 1-34 of human parathyroid hormone (PTH). It is regulatory-approved and studied in the scientific literature as a bone-anabolic agent for the treatment of osteoporosis. Unlike antiresorptive agents, studies attribute to it an effect that stimulates new bone formation. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Sincalide or Teriparatid?
- The highest available evidence level is "Исследование на людях" for Sincalide and "РКИ на людях" for Teriparatid. A higher evidence level means more robust data, but says nothing about suitability for an individual. The full body of evidence is on each peptide's own page.
- What is the legal status of Sincalide and Teriparatid in Germany and the United States?
- Германия: Sincalide — Неясно, Teriparatid — Рецептурный. США: Sincalide — Рецептурный, Teriparatid — Рецептурный. These are factual summaries with source and review date on the individual pages.
