Important Notice
This product is intended for laboratory and research use only. Not for human or veterinary use. By purchasing, you confirm this product will be used exclusively for in-vitro research purposes.
Reconstitution Required
This peptide ships lyophilized (dry powder) and requires bacteriostatic water to reconstitute before use. BAC water is sold separately.
Recommended: BAC water · stable for 21 days at 2-8°C once mixed.
When This Product May Not Suit Your Research
- ⚠If your research requires GMP-grade material for clinical applications — research-grade peptides are not intended for clinical use.
- ⚠If your lab lacks proper cold storage (-20°C freezer) — this peptide's stability may be compromised at higher temperatures.
- ⚠If your study protocol requires FDA-approved reference standards — contact USP or a certified reference material provider.

Overview
This listing supplies the retatrutide vial together with common laboratory consumables: one 10mg lyophilized retatrutide vial, bacteriostatic water, and graduated syringes. Retatrutide (CAS 2381089-83-2) is a triple-agonist peptide that engages three receptors simultaneously — the glucose-dependent insulinotropic polypeptide (GIP) receptor, the glucagon-like peptide-1 (GLP-1) receptor, and the glucagon receptor — making it one of the most-studied multi-receptor metabolic peptides currently in the research literature.
This listing groups the retatrutide vial, bacteriostatic water, and graduated syringes together for laboratory handling. CertaPeptides is a reseller: we assemble the supplied components and do not manufacture, formulate, or select the salt form of the retatrutide it contains. The compound is provided as a research reagent only.
Research Areas
Retatrutide is studied as a probe of simultaneous multi-incretin and glucagon-receptor signalling. Its three targets are distinct G-protein-coupled receptors: GLP-1 receptor activity is associated with incretin-mediated insulin signalling and central appetite pathways; GIP receptor activity contributes additional incretin signalling and is studied in relation to adipose function; glucagon receptor activity is studied in the context of hepatic glucose handling and energy expenditure. Published clinical research has characterised the compound in controlled trials: a Phase 2 obesity trial reported dose-dependent body-weight change in the study population (Jastreboff et al., 2023), and a separate Phase 2 trial investigated the GIP/GLP-1/glucagon agonist in people with type 2 diabetes (Rosenstock et al., 2023). These datasets are the standard reference points for researchers modelling triple-agonist pharmacology against single- and dual-receptor comparators.
Specifications
| Kit Component | Quantity | Specification |
|---|---|---|
| Retatrutide (lyophilized) | 1 × 10mg vial | CAS 2381089-83-2; ≥98% purity (supplier batch specification) |
| Bacteriostatic Water | 1 × 5ml vial | Sterile, 0.9% benzyl alcohol, endotoxin tested (<0.5 EU/ml); for refrigerated storage after laboratory reconstitution, per supplier handling guidance |

Storage: Store the lyophilized vial at −20°C. After reconstitution, store at 4°C and use within 28–30 days.
Quality & Verification
The retatrutide vial ships to a ≥98% supplier batch specification. In addition, selected lots are independently tested by Janoshik Analytical (HPLC and mass spectrometry), with batch reports searchable at certapeptides.com/verify. We do not test every batch and make no in-house testing claim — the model is a supplier specification on all units, plus third-party verification on selected lots. EU-based handling and fulfilment under CERTALAB S.R.L.
Frequently Asked Questions
What is included in the retatrutide kit?
The listing includes one 10mg lyophilized retatrutide vial (≥98% purity per supplier batch specification), one 5ml vial of bacteriostatic water, two 3ml Luer-lock syringes for reconstitution, and five 1ml graduated syringes — components supplied together for laboratory handling.
What does retatrutide target in research?
Retatrutide is a triple agonist that engages the GIP, GLP-1, and glucagon receptors simultaneously. This multi-receptor profile is why it is studied as a research tool for investigating combined incretin and glucagon-receptor signalling, in contrast to single- or dual-receptor peptides.
How is the retatrutide in the kit reconstituted?
Refer to laboratory SOPs and supplier handling guidance for reconstitution and refrigerated storage after laboratory reconstitution.
Is 10mg of retatrutide included in the kit?
Yes. The kit includes one 10mg vial of retatrutide in lyophilized form at ≥98% purity per supplier batch specification, with selected lots independently tested by Janoshik Analytical. Retatrutide is also available separately for researchers who need a different quantity.
Why buy the kit instead of components separately?
This listing supplies the retatrutide vial together with commonly used laboratory consumables (bacteriostatic water and graduated syringes) as a single order for convenience.
