Is Retatrutide for human use?

No. Retatrutide supplied by HALO Research Supplies is strictly for in vitro laboratory research use only (RUO). It is not approved by the FDA or any regulatory agency for human or veterinary use, diagnosis, or treatment.

What purity standard does HALO Research Supplies use for Retatrutide?

All HALO Research Supplies peptides including Retatrutide are verified at ≥98% purity by reverse-phase HPLC at an independent third-party accredited laboratory. Molecular identity is confirmed by mass spectrometry. A certificate of analysis (COA) is included with every shipment.

How should Retatrutide be reconstituted for research?

Reconstitute Retatrutide lyophilized powder with sterile bacteriostatic water or another validated research diluent. Add diluent slowly along the inner vial wall and swirl gently to dissolve. Do not vortex. Store reconstituted material at 4°C and follow the lot COA or institutional stability protocol. Store lyophilized material at −20°C protected from light.

Does HALO Research Supplies provide a COA with Retatrutide?

Yes. Every HALO Research Supplies shipment includes a certificate of analysis (COA) from an independent third-party ISO-accredited laboratory, documenting HPLC purity (≥98%), mass spectrometry identity confirmation, and batch number for full traceability.

What shipping conditions apply to Retatrutide?

HALO Research Supplies ships Retatrutide as lyophilized powder in gold-closure vials within 24 hours of order confirmation. Lyophilized peptides are stable at ambient temperature in transit for short durations; express shipping is recommended for large-quantity orders. Orders include all batch documentation.

Description
Additional information

Description

Retatrutide (LY3437943) is a tri-agonist peptide targeting GLP-1, GIP, and glucagon receptors simultaneously—a profile that distinguishes it from dual-agonist comparators in metabolic research models. HALO Research Supplies provides Retatrutide as lyophilized powder at ≥98% purity (HPLC), with each batch accompanied by an independent certificate of analysis confirming identity and purity.

In preclinical research settings, Retatrutide is studied for its effects on energy metabolism, adipose tissue signalling, and insulin secretion pathways. Available in a broad dose range (5 mg–100 mg) to support dose-response study design.

Format	Lyophilized powder
Purity	≥98% HPLC
