Albert's Verdict
GLP3-R activates all three incretin receptors simultaneously — the breadth of metabolic signaling here is unlike anything in a single-receptor agonist. This is the one I keep coming back to.

Product Description
GLP3-R is a triple-agonist peptide targeting GLP-1, GIP, and glucagon receptors simultaneously. This tri-agonist approach is being researched as the next frontier in metabolic peptide science, leveraging three complementary pathways for maximal metabolic modulation.
Molecular Profile:
- Classification: Triple GLP-1/GIP/Glucagon Receptor Agonist
- Targets: GLP-1R + GIPR + GCGR
- Mechanism: Tri-receptor incretin and glucagon activation
Research Applications:
- Triple receptor synergy versus dual/mono agonists
- Enhanced energy expenditure via glucagon receptor activation
- Superior body composition changes in preclinical models
- Hepatic lipid metabolism and NASH/NAFLD research
- Thermogenesis and brown adipose tissue activation
- Long-term metabolic homeostasis studies
Quality Standards:
- Purity: ≥99% verified by HPLC
- Third-party tested with COA included
- Available in 4 sizes for dose-response studies

Research FAQ — GLP3-R
Frequently asked questions about this compound for laboratory researchers.
What is Retatrutide / GLP-3-R?+
Retatrutide is an investigational triple-agonist research peptide that interacts with GLP-1, GIP, and glucagon receptors. Published Phase 2 trial data describe metabolic and body-composition effects under controlled clinical-research conditions.
Cited: PMID 37314979, PMID 38866447
How does Retatrutide differ from Semaglutide and Tirzepatide?+
Research literature characterizes Semaglutide as a single (GLP-1) agonist, Tirzepatide as a dual (GLP-1 + GIP) agonist, and Retatrutide as a triple (GLP-1 + GIP + glucagon) agonist. Published data on the additional glucagon-receptor activity suggest differentiated metabolic effects in clinical-research populations.
Cited: PMID 37314979
What dosing has been reported in Retatrutide clinical research?+
Phase 2 publications describe weekly subcutaneous administration of 1–12 mg in trial cohorts. Researchers should reference the cited NEJM publication and their IRB-approved protocols.
Cited: PMID 37314979
How is Retatrutide stored?+
Lyophilized Retatrutide should be stored at −20 °C protected from light. Reconstituted solution is typically held at 2–8 °C and used within 28 days. Refer to the product COA and your laboratory's SOP.

Lifelong Customer
Bio Infinity has truly made me a lifelong customer. My order was received quickly and wrapped well so the vials were safe in transit. Also, GLP3-R quality is unmatched. It has stopped my snack cravings and allows me to feel full on a normal portion size of my meal. In doing that, the weight has begun to just shed off. Amazing product!

Excellent purity and fast shipping
This product shipped quickly and arrived with no issues. It appears to be working, although waiting to adjust to it and get results. With a transition from a GLP-1 to GLP-3, it’s to be expected. This was my second time purchasing and will be purchasing again.
