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

Legit quality - verified myself

The purity checked out when I verified the COA on the lab's website. Shipped with ice packs and arrived in perfect condition. This is how every supplier should operate.

Switched from another supplier

My previous supplier was inconsistent. BioInfinity's COAs are verifiable and the quality is consistent batch after batch. Worth the switch.

You get what you pay for

Tried cheaper options before but the quality was sketchy. BioInfinity's third-party testing gives me confidence. Worth the price.

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.
