Research material · Retatrutide

Retatrutide research reference

Retatrutide, also referenced by the development identifier LY3437943, is an investigational peptide associated in the published literature with activity at the GIPR, GLP-1R and GCGR receptor systems. Peptique supplies it as a lyophilized laboratory research material in single vials and 10-vial kits.

01Compound profile

Retatrutide research material

Retatrutide is the name attached to the investigational peptide that public scientific records also list under the development identifiers LY3437943 and LY-3437943. Those identifiers establish the identity of the published reference substance. They are separate from the lot-specific analytical data that characterizes a physical production lot of research material.

Public pharmacology records classify the reference compound as a triple receptor agonist associated with three systems: the glucose-dependent insulinotropic polypeptide receptor (GIPR), the glucagon-like peptide-1 receptor (GLP-1R) and the glucagon receptor (GCGR). That classification is research context for the reference molecule. It is not a therapeutic, dosing, administration or clinical-use statement about any Peptique lot.

02Identification

Research material identification

Accurate compound identification and lot-level documentation are the two components a controlled study depends on. The identifiers below locate the public record for the reference substance; the lot report characterizes the material in the vial.

03Receptor profile

GIPR, GLP-1R and GCGR

GIPR

The glucose-dependent insulinotropic polypeptide receptor, one of the three systems in the published profile of the reference compound.

GLP-1R

The glucagon-like peptide-1 receptor, the second component of the multi-receptor classification recorded for the reference compound.

GCGR

The glucagon receptor, the third system in the published triple-receptor classification.

Reference, not result

Receptor information summarizes public records about the reference molecule. It does not establish the identity, purity or composition of a physical lot; the lot report does.

04Status

An investigational research compound

Retatrutide has been studied in a registered clinical development program under the LY3437943 identifier, and public trial records continue to describe it as investigational. It is not an approved medicine.

Published research and trial records give scientific context for the reference molecule. They do not independently establish the identity, purity, composition or characteristics of a separate physical research sample. That is what the lot-matched Certificate of Analysis is for.

05Formats

Single vials and 10-vial kits

Single vials

Eight nominal strengths from 5 mg to 60 mg, with automatic volume savings from the third vial.

10-vial kits

Nine kit configurations from 5 mg to 100 mg per vial. A kit is one lot, ten labeled vials, one carton.

Price per mg

The buy card shows the price per milligram for the selected configuration so laboratories can compare strengths and formats directly.

Bulk quantities

Laboratories that need more than standard kits can contact Peptique for wholesale terms.

06Research environment

Laboratory research applications

Supplied for use within appropriate research environments by personnel familiar with laboratory procedures, material identification, contamination control and experimental documentation.

Material preparation

Suited to laboratory workflows that call for a defined, documented research material inside an established experimental protocol.

Analytical workflows

Suited to controlled procedures where the researcher independently determines material suitability for the assay in hand.

Research documentation

Product identity and lot information support organized laboratory recordkeeping and later review.

Controlled handling

Researchers remain responsible for selecting handling procedures and contamination-control practices.

07Quality documentation

Lot-specific analytical information

Research conclusions should rest on the analytical documentation for the specific production lot being evaluated. General product-page information is not a substitute. The lot report records:

  • Compound identification
  • Production lot reference
  • Declared material quantity
  • Analytical testing information
  • Purity information where applicable
  • Testing methodology where documented
  • Certificate of Analysis for the lot
  • Research material traceability
08Traceability

Research records and lot control

01Identify

Confirm the compound, the selected strength and the lot identifier on the label.

02Match

Open the lot's report in the COA library and confirm the lot number matches.

03Review

Read the laboratory, the sample identifiers, the methods and the reported measurements.

04Preserve

Keep the product, lot, analytical, receipt and storage records with your research documentation.

09Laboratory handling

Storage and container integrity

  • Keep the original sealed container during storage
  • Protect from direct sunlight and excessive heat
  • Store lyophilized material at -20C, protected from light and moisture
  • Inspect container and closure integrity before laboratory use
  • Observe appearance and record it with the lot in your research records
  • Use appropriate contamination-control procedures

11Research FAQ

Retatrutide research questions

What is Retatrutide?
Retatrutide is a synthetic research peptide supplied by Peptique as a lyophilized laboratory material. It is sold for in vitro research and analytical use only.
What form is the material supplied in?
A lyophilized solid in a sealed glass vial. Appearance can vary by lot and does not indicate identity or purity; the lot's Certificate of Analysis does.
Is Retatrutide intended for human use?
No. Peptique supplies this product strictly for laboratory research. It is not a drug, food, supplement or cosmetic and is not for human or veterinary use.
Does Peptique provide dosing or administration instructions?
No. Peptique does not provide dosing, administration, injection, therapeutic or personal-use instructions for any product.
Why is the lot number important?
Analytical results apply to the tested lot only. The lot on your vial is what links the material in hand to its report in the COA library.
Is analytical documentation available?
Yes. A lot-matched Certificate of Analysis is published for every released lot and is linked from this page and from the COA library.
Is LY3437943 the same identifier as Retatrutide?
Yes. LY3437943 (also written LY-3437943) is the development identifier under which the reference compound appears in public scientific and trial records.
What does a 10-vial kit contain?
Ten vials of the selected nominal strength from one production lot, each labeled with the compound, the strength and the lot, packed in one carton that repeats the lot.
Is Retatrutide an approved medicine?
No. Public records describe it as an investigational compound. Peptique supplies it only as laboratory research material.
