Retatrutide

  • ≥99% HPLC
  • Mass Spec Verified
  • COA Per Lot
  • US Lab

Retatrutide is a synthetic 39-amino acid triple receptor agonist targeting the GIP (Glucose-Dependent Insulinotropic Polypeptide) receptor, GLP-1 (Glucagon-Like Peptide-1) receptor, and glucagon receptor simultaneously. It incorporates a fatty acid chain modification for extended plasma half-life via albumin binding. Retatrutide represents a novel class of triple incretin agonist research compounds, and is among the most recently characterized peptides in this research category. Heartland Bio Labs supplies Retatrutide as a lyophilized research compound of verified purity.

Retatrutide is a synthetic 39-amino acid triple receptor agonist targeting the GIP (Glucose-Dependent Insulinotropic Polypeptide) receptor, GLP-1 (Glucagon-Like Peptide-1) receptor, and glucagon receptor simultaneously. It incorporates a fatty acid chain modification for extended plasma half-life via albumin binding. Retatrutide represents a novel class of triple incretin agonist research compounds, and is among the most recently characterized peptides in this research category. Heartland Bio Labs supplies Retatrutide as a lyophilized research compound of verified purity.

Retatrutide is studied in preclinical and clinical research settings examining the simultaneous pharmacology of three metabolic receptor pathways. Published research has investigated its effects on insulin secretion, glucagon regulation, metabolic signaling, and receptor co-agonism mechanisms in animal and human study models. The addition of glucagon receptor agonism to the dual-incretin model (GIP + GLP-1) represents a distinct and actively studied pharmacological approach in metabolic biology research.

This compound is supplied strictly for research purposes. No clinical or therapeutic application is implied or represented.

Vial arrived sealed, labels clear and lot numbers match the COA exactly. Professional packaging.

How should I store this peptide?+

Lyophilized peptides should be stored at −20°C in a dry, light-protected environment. Avoid repeated freeze-thaw cycles. Once reconstituted, store at 2-8°C and use within 4-8 weeks depending on the compound.

What should I reconstitute it with?+

Bacteriostatic water or sterile water for research use. We recommend our companion BAC Water for consistency. Specific reconstitution volume depends on your research protocol — refer to the Specifications tab for solubility data.

How quickly do orders ship?+

Orders confirmed before 2:00 PM CT ship the same business day from our facility in Tulsa, OK. Standard US transit is 2-5 business days. Tracking provided at shipment.

Is the COA verified independently?+

Yes. Every lot is tested by HPLC for purity (target ≥99%) and mass spectrometry for molecular identity before release. The COA is generated from the actual lot data, not a generic template.

Can I get bulk or institutional pricing?+

Yes — qualified research facilities and high-volume orders receive tiered pricing. Contact us with your institution information and target quantities.
