Compound Identity
Retatrutide / LY3437943
Retatrutide is the official name associated with the
investigational peptide also referenced by the development
identifiers LY3437943 and
LY-3437943 in public scientific records.
These identifiers establish the identity of the published
reference substance. They should be distinguished from
lot-specific analytical data used to characterize an individual
production batch of physical research material.

Reference data:
molecular information above reflects the current public GSRS
Retatrutide substance record. It is reference information for
the published entity and does not replace analytical
characterization of a specific Royal Peptides production lot.
Research Targets
GIPR, GLP-1R & GCGR Research Profile
Public pharmacology records classify Retatrutide as a
triple receptor agonist associated with three
receptor systems: the glucose-dependent insulinotropic
polypeptide receptor, glucagon-like peptide-1 receptor, and
glucagon receptor.
GIPR
Glucose-Dependent Insulinotropic Polypeptide Receptor
GIPR is one of the three receptor systems associated with
the published pharmacological profile of Retatrutide.
GLP-1R
Glucagon-Like Peptide-1 Receptor
GLP-1R is another component of the multi-receptor profile
described for the Retatrutide reference compound in
scientific pharmacology records.
GCGR
Glucagon Receptor
GCGR represents the third receptor system included in the
published triple-receptor classification of Retatrutide.

Scientific Context
An Investigational Research Compound
Retatrutide has been investigated in an extensive clinical
development program under the LY3437943 development identifier.
Public trial records continue to identify Retatrutide as an
investigational compound.
Published research and clinical-trial records can establish
scientific context for the reference molecule, but they do not
independently establish the identity, purity, composition, or
characteristics of a separate physical research sample.
Identity
Compound Identification
Retatrutide, LY3437943, CAS 2381089-83-2, and UNII
NOP2Y096GV provide established identifiers for locating
corresponding public scientific records.
Entities
Receptor Classification
Public pharmacology resources associate the Retatrutide
reference compound with GIPR, GLP-1R, and GCGR.
Literature
Published Research
Peer-reviewed literature and registered studies provide
historical and experimental context concerning the
investigational Retatrutide molecule.
Evidence
Lot-Specific Documentation
Characterization of supplied research material should rely
on documentation corresponding to the applicable physical
production lot.
Research Kit Format
Retatrutide 10-Vial Research Kits
This product page is dedicated to
Retatrutide 10-vial research kits.
Available research quantities are organized through the product
variation selector above so laboratories can select among
currently available kit configurations without requiring a
separate indexed product page for every variation.
Each kit variation contains ten vials associated with the
selected nominal research quantity. Current pricing, variation
availability, and inventory status are displayed by the live
WooCommerce product record above.
Format
10-Vial Configuration
Multi-vial research kits consolidate ten vials within a
single product configuration while retaining the applicable
product and batch identification.
Variations
Multiple Research Quantities
Available kit quantities are managed as variations of this
primary Retatrutide kit product rather than separate
near-duplicate product pages.
Records
Batch Identification
Product and lot identification should be retained with
associated analytical and laboratory research records.
Procurement
Bulk Research Requirements
Laboratories requiring quantities beyond standard
10-vial research kits can review Royal Peptides wholesale
and bulk research procurement information.
Analytical Verification
Retatrutide Batch Documentation & COAs
Royal Peptides maintains analytical documentation for
applicable Retatrutide production lots. Analytical reports
should be evaluated in relation to the
specific batch or lot represented by the tested sample
rather than treated as universal documentation for every
Retatrutide material.
The Royal Peptides Certificate of Analysis library provides a
central location for reviewing available analytical records and
matching applicable documentation to research material.
01
Identify
Confirm the Retatrutide product, selected research quantity,
and available batch or lot identification.
02
Match
Locate analytical documentation associated with the
corresponding production lot whenever lot-level information
is available.
03
Review
Review the laboratory, sample identifiers, analytical
methods, reported measurements, and other information
contained in the report.
04
Preserve
Retain relevant product, lot, analytical, receipt, and
storage records within the laboratory's research
documentation.
Research Traceability
Compound Record vs. Production Lot
Scientific databases describe the referenced Retatrutide
substance. Published literature describes material and
experimental conditions evaluated by individual investigators.
Analytical documentation, by contrast, can provide information
about the specific sample evaluated from an individual
production lot.
Royal Peptides therefore distinguishes
reference-compound information from
lot-specific analytical documentation.
Maintaining that distinction supports clearer research records
and material traceability.

10-Vial Kits & Bulk Research Quantities
Laboratories evaluating larger research quantities can compare
Retatrutide 10-vial kits with
wholesale and bulk research procurement.
Royal Peptides maintains separate resources for standard kit
formats and larger-volume research requirements.
The Royal Peptides wholesale research guide covers multi-vial
procurement, unit and price-per-milligram comparison,
analytical documentation, lot traceability, fulfillment, and
considerations relevant to larger research orders.

Retatrutide FAQ
Retatrutide Research Questions
What is Retatrutide?
Retatrutide is the official name associated with the
investigational peptide compound also identified as
LY3437943 or LY-3437943. Public pharmacology records
describe it as a triple receptor agonist associated with
GIPR, GLP-1R, and GCGR.
Is LY3437943 the same identifier associated with Retatrutide?
Yes. LY3437943 and LY-3437943 are development identifiers
associated with Retatrutide in public scientific and
regulatory records.
What receptor systems are associated with Retatrutide research?
Public pharmacology records describe the Retatrutide
reference compound as an agonist associated with the
glucose-dependent insulinotropic polypeptide receptor
(GIPR), glucagon-like peptide-1 receptor (GLP-1R), and
glucagon receptor (GCGR).
What is the CAS number associated with Retatrutide?
The validated GSRS substance record lists CAS Registry
Number 2381089-83-2 for Retatrutide. This is a
reference-compound identifier and does not replace
lot-specific analytical documentation for supplied
research material.
What does a Retatrutide 10-vial kit contain?
This product is organized as a 10-vial research kit.
Selecting a variation above determines the nominal research
quantity associated with each vial in that kit. Current
variations and inventory are displayed by the live product
selector.
Are Retatrutide single vials available separately?
Yes. Royal Peptides maintains a separate Retatrutide
single-vial product for laboratories requiring individual
research quantities rather than a 10-vial kit.
Is analytical documentation available for Retatrutide?
Royal Peptides maintains analytical documentation for
applicable research-material lots. Researchers should use
the available lot or batch information associated with the
material to locate corresponding records in the Royal
Peptides COA library.
Why should a Retatrutide COA be matched to its lot?
An analytical report describes the sample evaluated by the
testing laboratory. Matching documentation to the applicable
production lot supports traceability between the physical
research material and its analytical record.
Is Retatrutide an approved medicine?
Retatrutide remains an investigational compound. Royal
Peptides supplies its Retatrutide material exclusively for
laboratory, analytical, and scientific research and not for
human or veterinary use.
Does Royal Peptides provide Retatrutide dosing or administration instructions?
No. Royal Peptides does not provide dosing, prescribing,
injection, administration, treatment, or personal-use
instructions for this research material.
