Cholecystokinin Dosage

Research-based dosing protocols, timing guidance, and reconstitution reference for Cholecystokinin. All information is for educational purposes only.

Quick Answer

Cholecystokinin (CCK) research primarily uses synthetic analogs like CCK-8. Dosage depends heavily on the specific analog, route of administration, and research goals. Typical doses range from picomoles to micrograms in animal studies. Human use is limited to diagnostic applications (sincalide). No established therapeutic dosage exists.

Standard Dosage Range

Research dosing range: No established therapeutic range. Research doses vary widely.

Educational reference only

These dosage ranges are derived from preclinical research and community protocols. No human clinical dose-ranging trials have established therapeutic doses for most research peptides. Always consult a qualified healthcare provider before starting any peptide protocol.

Dosage by Use Case

Gallbladder Function Testing (Sincalide)

0.02 mcg/kgSingle dose
Duration

Single administration

Sincalide (CCK-8 analog) is FDA-approved for gallbladder ejection fraction measurement. Administered intravenously by medical professionals.

Satiety Research

10–100 pmol/kgSingle dose prior to meal
Duration

Single administration

Primarily used in research settings to study appetite regulation. Dosage varies significantly based on analog and route (IV, subcutaneous).

Pancreatic Enzyme Stimulation

Variable, based on analogSingle dose
Duration

Single administration

Used in research to assess pancreatic function. Dosage is highly variable and dependent on the specific CCK analog used.

Timing & Frequency

For gallbladder function testing, sincalide is administered intravenously. For satiety research, analogs are administered shortly before meals. The short half-life necessitates acute administration for effects.

Cycle Guidance

Not applicable. CCK analogs are not used in cyclic therapeutic regimens. Research and diagnostic applications involve single or short-term administrations.

Frequently Asked Questions

What is the dosage of sincalide for gallbladder testing?
The standard dose of sincalide is 0.02 mcg/kg administered intravenously. It is given as a single dose by medical professionals.
Are there any therapeutic uses for CCK?
Currently, CCK analogs are primarily used for diagnostic purposes (gallbladder function). Research is ongoing to explore therapeutic applications in areas such as appetite regulation, but no approved therapeutic dosages exist.
