FAQ — Research Peptides & Molecular Compounds

What does “research use only” mean?

All products offered by PRG are strictly intended for scientific and laboratory research applications. They are not supplied for clinical, personal, or diagnostic use. Our materials are designed for controlled experimental environments and professional research programs.

What are research peptides and small molecules?

Research peptides and small molecules are laboratory-grade compounds used to study cellular signaling, mitochondrial function, metabolic pathways, and longevity-related biological processes.
They are produced under controlled manufacturing standards and used exclusively in scientific environments to support experimental research and discovery.

Are your products high-purity?

Yes. PRG supplies high-purity, European-manufactured research-grade compounds. Each batch undergoes analytical testing to verify identity and purity before distribution.

Do you provide Certificates of Analysis (COAs)?

Yes — COAs are available upon request.
We are also preparing to publish downloadable batch COAs directly on product pages soon.

Are your compounds third-party tested?

Yes. Every batch is subject to independent analytical testing to verify:

  • Identity

  • Purity

  • Stability

  • Structural integrity

This ensures reliable performance in precision laboratory environments.

Do you offer a purity guarantee?

Yes. All PRG compounds are manufactured to high-purity research standards and undergo analytical verification before release.

If an accredited third-party laboratory performs independent purity testing and the result does not match the stated specification for the batch received, we will provide a full refund or replacement.

To submit a verification request, please include:
• Your order number
• Batch number
• Accredited third-party purity report (HPLC/MS or equivalent)

This guarantee applies only to purity-based discrepancies and products used exclusively for research purposes in accordance with our guidelines.

Where are your peptides manufactured?

All PRG compounds are manufactured in Europe under advanced quality systems.
Each product undergoes analytical validation and purity testing to support consistent and transparent research-grade quality.
