FAQ — Research Peptides & Molecular Compounds

What does “research use only” mean?

“Research use only” (RUO) indicates that PRG products are supplied exclusively for in vitro scientific research or further manufacturing use within controlled laboratory environments. They are not intended for clinical, diagnostic, therapeutic, personal, human, or animal use. All materials are designed for professional research applications and experimental programs only.

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)?

All PRG research materials are analytically tested for purity and identity in accordance with EU laboratory standards. Manufacturer Certificates of Analysis (COAs) are available upon request. If independent third-party analytical testing confirms results consistent with our published specifications, PRG may reimburse the verified laboratory testing costs following review.

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.

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.

Do you ship internationally?

Yes. PRG provides secure, tracked worldwide shipping with discreet packaging.

How long does shipping take?

Processing typically occurs within 24 hours on business days.
Delivery times vary by region, but most shipments arrive within:
