⚖️ What is Retatrutide?
Retatrutide is a tri-agonist peptide designed to bind GLP-1, GIP, and glucagon receptors. Originally studied for obesity and metabolic syndrome, it has shown promise in supporting:
- Appetite regulation and caloric intake
- Improved insulin sensitivity
- Fat metabolism research
- Multi-receptor synergy studies
⚠️ Why Mannitol-Free Matters
Most commercial peptides contain mannitol as a bulking agent. We eliminate it to preserve:
- Receptor interaction purity
- Accurate microdosing
- Better solubility profiles
- Less filler = more reliable data.
📆 Storage & Reconstitution
Before Reconstitution:
- Keep at -20°C or below
- Avoid repeated freeze-thaw cycles
After Reconstitution:
- Store at 2–8°C (refrigerated)
- Use sterile bacteriostatic water
- Use within 7–14 days (or aliquot + refreeze)
🧮 Research Use Only

❓ Frequently Asked Questions
Where can I buy Retatrutide peptide?
Right here. Our verified Retatrutide peptide ships direct from our U.S. facility and is available in various formats.
What’s the difference between Retatrutide, Semaglutide, and Tirzepatide?
Retatrutide is a triple agonist. Semaglutide is GLP-1 only. Tirzepatide is GLP-1 + GIP. Retatrutide adds glucagon activation for broader effect modeling.
Can you ship to my lab or university?
Yes, we regularly supply institutional researchers, labs, and independent study groups across the U.S. and abroad.
Do you provide COAs or lab reports?
Yes. All vials ship with batch-specific COA. Full SDS available upon request.
