Retatrutide (Reta)

Retatrutide (Reta) is a next-generation investigational peptide currently being studied as a triple agonist targeting the GLP-1, GIP, and glucagon receptors. This multi-pathway activity has made it one of the most closely watched compounds in the field of metabolic and weight management research.

In preclinical and early clinical studies, Retatrutide has been explored for its potential to influence appetite regulation, glucose metabolism, and weight reduction. Its broad receptor activity differentiates it from single-pathway GLP-1 analogs such as semaglutide.

Research Notes

Retatrutide is a synthetic peptide analog currently under investigation for its ability to activate GLP-1, GIP, and glucagon receptors, contributing to research on glucose metabolism, appetite regulation, and energy expenditure. Its unique tri-agonist mechanism distinguishes it from previous incretin-based peptides.

All Poly Biotech peptides are produced using a lyophilization (freeze-drying) process that guarantees product stability during shipping and storage. This process removes moisture under controlled low-pressure conditions, creating a stable white powder that preserves the peptide’s structure and potency.

Before reconstitution:

• Lyophilized peptides remain 100% stable for 3–4 months during normal shipping and storage.
• Vials can be safely kept at room temperature if they will be used within a few weeks or months.
• For long-term storage (several months to years), keep vials in a freezer at -20°C to -80°C (-4°F to -112°F) to maximize stability.
  

After reconstitution:

• Once mixed with bacteriostatic water, peptides should be stored in the refrigerator (2–8°C / 36–46°F).
• Reconstituted peptides remain stable for up to 30 days when refrigerated.
• Keep all vials away from direct light and heat to maintain product integrity.
  

By following these guidelines, you’ll ensure your peptides retain their full quality and effectiveness from shipment to final use.
