Product details

Dual-receptor incretin research.

Tirzepatide is a 39-amino-acid synthetic peptide characterised as a dual agonist at the GLP-1 receptor (GLP-1R) and glucose-dependent insulinotropic polypeptide receptor (GIPR). This two-receptor profile places Tirzepatide between single-pathway Semaglutide and triple-agonist Retatrutide in incretin and metabolic-signalling research. This variable product supplies 10 MG or 20 MG lyophilized research vials within the NZM-Labs research peptide range.

Every production lot is independently analysed by HPLC and mass spectrometry, with lot-specific documentation available for matching the vial to its analytical record. For laboratory research only.

Weight Reduction

Tirzepatide is a 39-amino-acid GLP-1 / GIP dual agonist. The dual receptor profile produces a steeper satiety-pathway response than single-pathway GLP-1, with downstream effects on body weight and adiposity in both research models and published clinical literature.

The reference SURMOUNT-1 trial reported a mean body-weight reduction of −22.5% from baseline at 72 weeks in the highest published study arm, with monotonic responses across published study arms. Results referenced for in-vitro / animal-model protocol design only.

A1C ↓ 1.9–2.6%

Glycemic Control

GLP-1 / GIP dual agonism amplifies insulin secretion and steepens the glycemic-response curve compared with single-pathway GLP-1 agonism. The reference literature reports HbA1c reductions of 1.87% to 2.59% across published weekly study arms in T2D research populations.

up to 73%

Liver Fat Reduction

GLP-1 / GIP co-agonism engages hepatic lipid handling beyond what GLP-1 alone produces. The Tirzepatide MASLD substudy reported relative liver-fat reduction of up to 73% at 52 weeks measured by MRI-PDFF in the highest published study arm.

Improved

Metabolic Flexibility

Beyond direct glycemic effects, dual incretin agonism improves measured markers of insulin sensitivity (HOMA-IR) and metabolic flexibility in research populations - a profile that distinguishes Tirzepatide from single-pathway references in published comparison studies.

Questions?
We have answers.

(01)

Why dual agonism and not single GLP-1?

Adding GIP-receptor activation amplifies the satiety and glycemic effect of GLP-1 without proportionally amplifying GI side effects. Most published metabolic-research protocols using dual-pathway compounds reference Tirzepatide as the canonical example.

(02)

How is the Certificate of Analysis verified?

Every lot is sent to Janoshik Analytical for independent HPLC and mass spectrometry testing. The COA you receive is theirs, not ours - searchable by lot number on our Science page, no account required.

(03)

How is the product shipped?

Lyophilized vials are shipped across the EU. Store sealed vials below 16°C after delivery. Typical delivery takes 3–5 working days.

(04)

Is this a research product?

Yes. NZM peptides are sold strictly for in vitro and animal research use only. They are not for human consumption, off-label use, or clinical application. Please consult applicable local regulations before ordering.

(05)

What is the Tirzepatide research peptide price?

The current Tirzepatide price is shown on this page. Pricing applies to B2B research procurement only and may vary by lot, format, and availability.

(06)

Can research customers buy Tirzepatide from NZM-Labs?

Yes. Research customers can order Tirzepatide through NZM-Labs for in vitro and animal research use only. It is not sold for human consumption, clinical use, or self-administration.
