Research use only. Survodutide: Research Guide to the GLP-1 and Glucagon Receptor Peptide is supplied for laboratory research. It is not a drug, food, cosmetic, or dietary supplement. It is not FDA-approved. It is not for human or veterinary administration. This page does not give a dose or a method of administration. A study cited on this page describes that study’s own test article. It does not make this lot an approved medicine. To check a fact, open the PubMed or DOI link, confirm the authors and year, and match the paper’s compound name, CAS number, or sequence to the specification table. The full method is on the research desk page. Identity and purity for a lot are only what that lot’s certificate of analysis reports. An HPLC percentage is not a sterility result and not an endotoxin result unless the certificate prints those tests.
Survodutide (BI 456906) is a synthetic peptide with CAS 2805997-46-8. The public compound record gives the formula C192H289N47O61 and describes the substance under the glucagon-like peptide research names survodutide and BI-456906. Published descriptions place it at the GLP-1 receptor and the glucagon receptor.

Analytical testing notes for Survodutide
Survodutide is identified in this guide as CAS 2805997-46-8, formula C192H289N47O61. An identity test compares a measurement with those values. A mass spectrum is the usual measurement for a peptide. FTIR, when a certificate uses it, is a supporting infrared fingerprint and is less specific for closely related sequences.
Survodutide carries a fatty-acid or other lipophilic modification, so it is among the later-eluting peptides on a C18 column. Laboratories often raise the acetonitrile fraction, the column temperature, or move to a C8 or C4 column so the main peak is sharp enough to integrate. The mass used for identity has to include the lipid chain and linker, not only the amino-acid backbone. Area-percent purity still ignores water and counterion.
HPLC purity for this material is an area-percent result at the wavelength and gradient the laboratory states, commonly ultraviolet detection near 214 nm on a reversed-phase column. The instrument is a gradient pump, injector, column oven, and UV or diode-array detector. That percentage is not the number of milligrams in the vial. Water, acetate, trifluoroacetate, and other UV-silent material can dominate the gross weight while the purity figure stays high. Net peptide content, from an assay or amino-acid analysis, is the separate result to read when the certificate reports it.
A sterility test and an endotoxin test are not included in a chemical purity result. The compendial sterility test is a culture method (USP <71>): membrane filtration or direct inoculation into fluid thioglycollate medium and soybean-casein digest medium, incubated for 14 days. A PCR sterility screen uses a thermal cycler to detect microbial DNA and is a different method. The endotoxin test (USP <85> LAL, or USP <86> recombinant Factor C) reports endotoxin units with an incubating reader or a cartridge reader. Use a result only when that method is printed on the lot certificate. One published example in this catalog states that the report does not cover microbial contamination or endotoxins. The full description of equipment, standards, and how US laboratory accreditation works is in peptide analytical testing. Lot records are on the COA page.
