How should GLP-2 TZ be stored?

In lyophilized powder form, GLP-2 TZ is stable at room temperature short-term but should be refrigerated (2–8°C) for longer storage and kept away from light and moisture. Once reconstituted, keep refrigerated and use within 30 days. Avoid freeze-thaw cycles.

Is GLP-2 TZ approved by the FDA?

A GLP-2 receptor agonist is FDA-approved for short bowel syndrome. NextSelf Labs’ GLP-2 TZ is a distinct research-grade compound, not FDA-approved for any use, and is sold strictly as a research chemical for laboratory research.

What is the purity of your GLP-2 TZ?

All NextSelf Labs GLP-2 TZ is manufactured to ≥99% purity and verified by third-party laboratories using HPLC and mass spectrometry. The Certificate of Analysis for every batch is available on this page — match the batch number on your vial to the COA header to verify.

What has GLP-2 been studied for?

Research on GLP-2 has focused on its trophic effects on the small intestine, including stimulation of mucosal growth, improved nutrient and fluid absorption, and support for intestinal barrier integrity.

How does GLP-2 differ from GLP-1?

Though co-secreted from the same intestinal L-cells, GLP-1 and GLP-2 have distinct research profiles. GLP-1 is studied primarily for its effects on insulin secretion and appetite, while GLP-2 research centers on intestinal tissue growth and gut barrier function.

Do I need a prescription to purchase GLP-2 TZ?

No. NextSelf Labs sells GLP-2 TZ as a research chemical for laboratory use only.

About the Peptide

The gut’s own growth signal.

GLP-2 TZ is a synthetic, protease-resistant analog of glucagon-like peptide-2 (GLP-2), a 33-amino-acid hormone naturally co-secreted with GLP-1 from intestinal L-cells in response to nutrient intake. Native GLP-2 is rapidly degraded by the enzyme DPP-4; stabilized analogs like GLP-2 TZ are designed to extend its research window.

Gut health rarely gets the attention it deserves until something goes wrong. Digestive sensitivity, nutrient malabsorption, and a compromised gut lining touch far more of daily life than most women realize: energy, skin, mood, and immune resilience all trace back, in part, to intestinal integrity.

Published research has documented GLP-2’s role in stimulating growth of the intestinal mucosa, enhancing nutrient and fluid absorption, slowing gastric emptying, and supporting the tight-junction proteins responsible for gut barrier integrity. It remains one of the most studied hormones in the intestinal repair and gastrointestinal research literature.

Research Applications

Gut health, taken seriously.

The intestinal lining does more work than most research gives it credit for. GLP-2 TZ is studied for supporting the tissue-level foundation of digestive and absorptive health.

Intestinal Tissue Growth

GLP-2 has been extensively studied for its trophic effect on the intestinal epithelium, supporting mucosal growth and repair of the gut lining.

Nutrient Absorption Research

Published research documents GLP-2’s role in enhancing nutrient and fluid absorption by increasing intestinal surface area and slowing gastric emptying.

Gut Barrier Integrity

Studies have examined GLP-2’s ability to support the tight-junction proteins that maintain a healthy, less permeable intestinal barrier.
