Standard Dosage Range

Research dosing range: 0.2 mcg/kg (diagnostic)

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

Pancreatic Function Testing (SecreFlo, ChiRhoStim)

0.2 mcg/kgSingle dose
Duration

Single administration

Administered intravenously as a bolus injection. Used to stimulate pancreatic fluid secretion and measure bicarbonate output.

Gastrinoma Diagnosis (Zollinger-Ellison Syndrome)

0.4 mcg/kgSingle dose
Duration

Single administration

Administered intravenously as a bolus injection. Used to stimulate gastrin release from gastrinoma cells.

Research Purposes (Neurological/Autism Studies)

Variable, based on study protocolVariable, based on study protocol
Duration

Variable, based on study protocol

Dosages in early research studies on autism have varied significantly and results have been inconsistent. Currently not a standard treatment.

Timing & Frequency

For diagnostic purposes, secretin is administered by a medical professional during the testing procedure. The timing is critical to the test protocol and will be determined by the specific diagnostic test being performed.

Cycle Guidance

Secretin is not typically used in cycles due to its diagnostic application and short half-life. Research use protocols would dictate any potential cycling strategies, but these are not standardized.

Reconstitution Reference

Quick reference for reconstituting Secretin. For custom vial sizes and concentrations, use the Reconstitution Calculator.

Common Vial Size16 mcg (SecreFlo)
BAC Water Volume8 mL sterile saline (SecreFlo) to yield 2 mcg/mL
Concentration & Draw2 mcg/mL when reconstituted as directed (SecreFlo). Requires specific dilution calculations based on patient weight for diagnostic use.
StorageRefrigerate at 2–8°C after reconstitution. Use immediately after reconstitution (within 3 hours).
StabilityUse immediately after reconstitution. Lyophilized powder stable until expiration date per manufacturer specifications.
Use the Reconstitution Calculator → for precise injection volumes based on your exact vial size, water volume, and desired dose.

Frequently Asked Questions

What is the standard dose of secretin for pancreatic function testing?
The standard dose for pancreatic function testing is 0.2 mcg/kg body weight, administered intravenously as a single bolus injection.
How is secretin administered?
Secretin is administered intravenously by a medical professional. The specific administration protocol depends on the purpose of the test (e.g., pancreatic function testing, gastrinoma diagnosis).
Can secretin be taken orally?
No, secretin is not typically administered orally. Intravenous administration is required for its diagnostic applications. Oral administration is unlikely to be effective due to peptide degradation in the gastrointestinal tract.
What are the possible side effects of secretin?
Common side effects include flushing, headache, and abdominal discomfort. Rare but more serious side effects can include allergic reactions and changes in blood pressure. Secretin should only be administered under medical supervision.
