High-purity Retatrutide without excipients now available in bulk quantities for laboratories, clinics, and verified resellers.

United States, 24th Jul 2025 – BulkGLP, a leading supplier of high-purity research peptides, has announced the launch of mannitol-free Bulk Retatrutide, now available in wholesale quantities for research laboratories, clinical facilities, and authorized resellers.

This new formulation offers 98%+ purity with zero excipients, providing researchers with a cleaner, more stable compound for long-term studies on obesity, metabolic health, and glucose regulation. By removing mannitol, a common filler used in many peptide formulations, BulkGLP is meeting the growing demand for unadulterated Retatrutide that delivers consistency and precision for sensitive research environments.

Retatrutide: The Next-Generation Research Peptide

Retatrutide is a triple agonist peptide that simultaneously activates GLP-1, GIP, and glucagon receptors. This unique mechanism has shown remarkable potential in clinical trials, achieving superior weight loss and metabolic improvements compared to existing dual agonists like Tirzepatide and single agonists like Semaglutide.

With its ability to influence multiple pathways involved in appetite regulation, glucose metabolism, and energy balance, Retatrutide has quickly become one of the most sought-after peptides in advanced obesity and diabetes research.

As interest in this compound accelerates, research labs worldwide are seeking reliable sources of high-purity Retatrutide in larger quantities. BulkGLP’s new mannitol-free bulk Retatrutide offering meets this demand with superior quality and batch consistency.

Why Mannitol-Free Retatrutide Matters

Many peptide suppliers rely on mannitol as an inexpensive excipient to improve lyophilization and handling. However, for sensitive research applications, fillers like mannitol can:

  • Introduce unnecessary variability in experiments
  • Alter stability or solubility under certain conditions
  • Interfere with analytical measurements or compound isolation

By removing mannitol entirely, BulkGLP delivers pure Retatrutide, exactly as intended, with no hidden additives.

“Researchers deserve true, uncompromised compounds for their work,” said a spokesperson for BulkGLP. “Our Mannitol-Free Retatrutide gives labs complete confidence that what they’re testing is exactly what’s on the label—nothing more, nothing less.”

Bulk Retatrutide for Serious Research Projects

BulkGLP specializes in bulk peptide supply for labs that require long-term consistency. The company’s new bulk Retatrutide program offers:

  • 10-vial packs – ideal for mid-sized labs
  • 50-vial wholesale lots – perfect for clinical trials or institutional research
  • 100+ vial custom orders – designed for resellers and large-scale projects

Every bulk order is batch-matched, meaning all vials come from the same production lot. This eliminates inter-batch variability, ensuring that large-scale studies maintain reproducibility over weeks or months.

Quality, Purity & Documentation

All BulkGLP peptides, including Retatrutide, undergo:

  • HPLC analysis for purity verification
  • Mass spectrometry testing for molecular identity
  • Independent third-party verification upon request

Each bulk shipment includes a Certificate of Analysis (CoA) documenting batch purity and test results.

Typical purity levels for BulkGLP Retatrutide exceed 98%, making it suitable for even the most demanding research applications.

Secure Packaging & Cold-Chain Shipping

Bulk Retatrutide is supplied as a lyophilized powder in sealed sterile vials to ensure maximum stability. For large shipments, BulkGLP uses temperature-controlled, insulated packaging with desiccants to protect against moisture and environmental fluctuations.

Express delivery ensures minimal transit time, reducing the risk of temperature exposure. Bulk shipments can also be split into multiple cold-chain parcels for international orders.
