Independently verified99.90% pure
Every batch is analyzed by an accredited US third-party laboratory before it ships.
Identity, purity, and concentration confirmed by MZ Biolabs (Tucson, AZ), a US DEA-licensed analytical facility, via HPLC and mass-spectrometry identity confirmation under GLP standards.
Our third-party certificates of analysis are published on our website — no login required.
Mass-spectrometry analysis verifies the peptide’s molecular mass matches the listed specification.
Storage & handling
Peptides require cold-chain handling to preserve integrity throughout your research timeline.
- Before reconstitution: Store the lyophilized vial refrigerated at 2–8 °C (36–46 °F), away from direct sunlight and heat.
- After reconstitution: Keep refrigerated at 2–8 °C and use within 30 days. Do not freeze the reconstituted solution.
- Sterile sealed glass vial to maintain integrity in transit and storage.
- Diluent and laboratory supplies are not included and must be sourced separately for research.
Why source GLP-3 RT from Sports Technology Labs
Research peptides vary widely in identity, purity, and actual peptide content between suppliers, which makes independent third-party verification by HPLC and mass spectrometry essential. Sports Technology Labs publishes its certificates of analysis on the website.
Identity, purity, and concentration verified by MZ Biolabs (Tucson, AZ), an accredited US laboratory.
Vials are freeze-dried and refrigerated to help preserve peptide stability.
Accurate, verifiable specifications with no discreet payment methods or mislabeling.
Transparent business, standard payment methods, no misrepresentation.
What is GLP-3 RT?
GLP-3 RT (LY3437943) is a synthetic single-chain peptide of approximately 39 amino acids, engineered as a triple receptor agonist that engages the glucagon receptor (GCGR), the glucose-dependent insulinotropic polypeptide receptor (GIPR), and the glucagon-like peptide-1 receptor (GLP-1R) (ref. 1). It is produced synthetically for laboratory use.
GLP-3 RT is an experimental research compound supplied strictly for laboratory research. Sports Technology Labs makes no claims regarding its effects, and nothing in this listing should be interpreted as describing outcomes in humans or animals.
Important regulatory information
GLP-3 RT is investigational and has not been approved by the FDA for any therapeutic indication. It is not a dietary supplement, drug, or food, and is not lawful to market for human ingestion.
GLP-3 RT is not individually named on the current WADA Prohibited List, but as an unapproved investigational substance it falls under the S0 (Non-Approved Substances) catch-all, and the broader class of GLP-1/GIP/glucagon receptor agonists is under active anti-doping scrutiny.
In the United States, GLP-3 RT is not a scheduled or controlled substance and may be legally purchased and possessed for laboratory research use.
Sports Technology Labs are chemical suppliers, not medical providers. We do not condone or encourage consumer use of research compounds.
