Retatrutide (GLP-3)
GLP-1, GIP & Glucagon Tri-Agonist Peptide 30mg
Original price was: $290.00.$203.00Current price is: $203.00.
Retatrutide (GLP-3) is a cutting-edge tri-agonist peptide that is transforming the field of metabolic research. Engineered to simultaneously activate three key metabolic receptors—GLP-1, GIP, and GCGR (glucagon)—this multifunctional compound offers a comprehensive and synergistic approach to modulating appetite signaling, enhancing insulin function, and accelerating fat metabolism pathways in research settings. Available in 5 mg and 30 mg single-bottle sizes.
⚠️ Important Disclaimer
Research purposes only. Not for human consumption or therapeutic treatment.
Retatrutide brings three related metabolic signals into one research compound. It interacts with GIP, GLP-1 and glucagon receptors—receiving points that help cells respond to chemical messages. That makes its main research distinction the ability to examine several connected signals together.
What researchers investigate
- Three-receptor signaling: Compare the response from GIP, GLP-1 and glucagon receptors within the same experimental system.
- Energy regulation: Study the cellular signals involved in glucose handling and energy balance.
- Comparative research: Compare a three-receptor compound with materials that target one or two receptors.
What makes it different?
Its defining feature is its three-receptor profile. Tirzepatide targets GIP and GLP-1 receptors; retatrutide also engages the glucagon receptor.
Research findings describe the materials and conditions studied; they do not predict results in people.

What the results mean
- Identity: checks whether the tested sample matches the reported compound.
- Purity: measures the chromatographic purity reported by the method; it is different from milligrams in a vial.
- Content: reports how much material was measured in the tested sample.
A certificate documents the tested sample and the tests shown. It does not establish clinical effectiveness or regulatory approval. Purity testing is not a sterility test.
Handling & Storage
Good handling protects the integrity of your research sample. Use the product label, any matching technical documentation and your laboratory’s approved procedure for this exact material.
- Check before opening: confirm the compound, vial size and relevant report.
- Keep dry material protected: minimize unnecessary exposure to moisture, light and temperature changes; follow the storage instructions supplied with your vial.
- Choose the solvent for the material: solubility and stability vary. Water, saline, PBS and acidic solutions are not automatically interchangeable.
- Label prepared samples: record the contents, concentration, preparation date and validated storage period. Use aliquots where appropriate to reduce repeated handling.
There is no universal reconstitution volume or shelf life for every peptide. A clear solution alone does not confirm identity, stability or sterility.
FAQ
What is the labeled amount?
5 mg or 30 mg per vial. For a blend, this is the total of the listed components. A concentration is calculated only after the final solution volume is known.
Where can I check the testing?
The Certificate of Analysis tab displays COA7924 from Bioviridian Inc. Open the full-size image and use the lab’s verification page to check the report. Confirm the sample size and how the report relates to your vial.
Is purity the same as the amount in the vial?
No. Purity is a measurement made by an analytical method; content is the measured amount of material. A high purity percentage does not, by itself, tell you how many milligrams are present.
How should I interpret the research?
A receptor response is a laboratory measurement, not a prediction of weight loss or another result in a person.
