Know your compound
What is GLP-3 RT?
This compound belongs to the incretin analog class studied for activity at multiple receptors involved in metabolic regulation. Published clinical and preclinical literature on this compound class is extensive and rapidly developing.
Supplied as a lyophilized powder for laboratory research use only. Nothing on this page describes an approved therapy or a use in humans; it summarises what published research has examined.
- C-terminusAmide (–NH₂)
- Residue 17The Lys17 ε-amine carries a single AEEA spacer, then γ-glutamate, then an eicosanedioic (C20) diacid — a shorter linker than the two-AEEA arrangement used by the GLP-1 and dual-agonist analogs.

Read left to right from the N-terminus. Mass spectrometry checks each lot against this sequence — that result is the “Identity” line on the certificate.
Identity
What the molecule is.
- Amino acids
- 39
- How many residues make up the chain.
- Molecular formula
- C221H342N46O68
- The atom count in a single molecule.
- Molecular weight
- 4731.3 g/mol
- The mass of one mole. You need this figure to calculate concentration when reconstituting.
- CAS
- 2381089-83-2
- The registry number that identifies this substance unambiguously in chemical databases.
Verification
How we know the material matches the label.
- Purity
- ≥99% (RP-HPLC, per lot)
- The share of the material that is the target compound, measured by reverse-phase HPLC on every lot — not a blanket brand claim.
- Identity method
- LC-MS confirmed
- Mass spectrometry compares the material against the expected sequence to confirm it is the right molecule.
- Documentation
- Certificate of Analysis, per lot
- The certificate for your specific lot is published before it ships and stays searchable by lot number.
Handling
What arrives, and how it is kept.
- Form
- Lyophilized powder
- The physical state the vial arrives in.
What the literature examines
Studied pathways
Summaries of what published research has investigated. Preclinical unless stated otherwise — not claims about this product.

Questions
GLP-3 RT FAQ
Is GLP-3 RT approved by the FDA?
No. GLP-3 RT is not an FDA-approved drug and is not approved for human or veterinary use. It is supplied exclusively as a research material for laboratory use, and it is not intended to diagnose, treat, cure, or prevent any disease.
Does this lot come with a Certificate of Analysis?
Yes. Every lot is assayed by an independent U.S. laboratory for purity and identity, and the certificate for the lot you receive is published in our COA library — you can read it before you order.
How is purity determined?
Purity is quantified by reverse-phase HPLC against a reference standard, and identity is confirmed by mass spectrometry. Both results appear on the lot certificate.
How should this be stored?
Lyophilized material is typically stored cold and protected from light. Handling and storage are the responsibility of the receiving laboratory; refer to the lot documentation for specifics.
How does the buy-one-get-one offer work?
Every second vial is free, sitewide and automatically. Add two vials and you pay for one; add six and you pay for three. Compounds can be mixed, there is no code, and there is no limit.
When will my order ship?
Orders are processed promptly and shipped with tracking. Free US shipping applies over $100; Priority shipping is $8.95 otherwise.
