Teduglutide
FDA ApprovedSince 2012
Also known as Gattex, Revestive
Function
Primary
Short bowel syndrome
Secondary
Intestinal mucosal growth research
Mechanism
DPP-4-resistant GLP-2 analog that increases intestinal villus height, crypt depth, and nutrient absorption.
Evidence
Clinical RCT (Phase III)
Research
Phase III STEPS program
Dosing
Range
0.05 mg/kg/day
Frequency
Daily
Route
Subcutaneous
Administration & Technique
Subcutaneous (SubQ)
Default route for most research and therapeutic peptides — best absorption for reconstituted powder.
Device31G × 5/16" insulin syringe (U-100). 100 units = 1 mL.
TechniquePinch skin at abdomen (2" from navel), outer thigh, or love handle. Insert at 45–90°. Rotate sites daily to prevent lipohypertrophy. Alcohol-swab site, air-dry, inject slow, hold 5 sec.
Injection & Application Sites
Front
Back
Subcutaneous (SubQ)
- Abdomen — 2 in (5 cm) away from the navel, either side. Fastest, most consistent SubQ absorption.
- Flank / love handle — Lateral fat pad above the hip. Good rotation site when the abdomen is tender.
- Outer thigh — Upper outer quadrant, a hand-width below the hip. SubQ pinch at 45°.
Diagram is a general illustration, not a medical instruction. Rotate sites every injection, keep 1 in (2.5 cm) between recent sites, and avoid scars, moles, bruises and the navel area.
Cycling
Continuous daily therapy with periodic colonoscopy.
Timing & Interactions
When to take
No strict time-of-day requirement. Dose consistently at the same time daily and rotate injection sites. Follow the per-peptide dosing section above.
Do not combine with
- ·Avoid stacking with peptides that share the same receptor or mechanism without clinical guidance.
- ·Avoid combining with alcohol or immunosuppressants unless cleared by a clinician.
Complements
- ·Most peptides pair safely with baseline nutrition, sleep, and resistance training.
Storage & Reconstitution
Powder (Pre-Reconstitution)
Lyophilized powder: refrigerate 2–8°C for up to 24 months, or freeze at –20°C for extended storage. Keep sealed, desiccated, and protected from light.
After Reconstitution
After reconstitution with bacteriostatic water, refrigerate at 2–8°C and use within 28 days. Discard if cloudy, discolored, or precipitated.
Notes
Do not freeze after reconstitution — freeze/thaw cycles degrade most peptides.
