Frequently Asked Questions

Essential information about our research-grade peptides and quality standards.

What are research peptides?

Peptides are short chains of amino acids linked by peptide bonds, typically consisting of 2-50 amino acids. They serve as the building blocks of proteins and play crucial roles in biological processes.

Research peptides are synthesized versions of naturally occurring peptides, manufactured to precise specifications for use in scientific studies.

Key characteristics: High purity (≥98%), lyophilized form for stability, accompanied by Certificates of Analysis (COA), and manufactured under strict quality control protocols.

What does peptide purity mean and why does it matter?

Peptide purity refers to the percentage of the target peptide present in a sample, measured via High-Performance Liquid Chromatography (HPLC).

Our Standard: All our research peptides maintain ≥98% purity, verified by third-party laboratory testing and documented in our Certificates of Analysis.

Higher purity is critical for research because impurities can interfere with experimental results and compromise the reproducibility of studies.

What form do your peptides come in?

All products are supplied in lyophilized powder form within sterile, sealed vials. This format provides:

Maximum stability: Extended shelf life compared to liquid solutions
Precise measurement: Researchers can work with desired quantities
Contamination protection: Sealed vials prevent environmental exposure
Shipping durability: Powder form is more stable during transit

How should research peptides be stored?

Lyophilized peptides:

Store at -4°F for long-term storage (up to 24 months)
Store at 36-46°F (refrigerated) for short-term storage (up to 3 months)
Keep away from light, moisture, and repeated temperature fluctuations

Who can purchase research peptides?

We supply research-grade peptides to:

Academic and university research laboratories
Pharmaceutical and biotechnology companies
Independent research institutions
Licensed professionals conducting legitimate scientific research

How do you ensure peptide quality?

We maintain rigorous quality control through a multi-step verification process:

HPLC Analysis: Every batch tested to verify ≥98% purity
Mass Spectrometry: Molecular weight confirmation for peptide identity
Third-Party Testing: Independent laboratory verification
Sterility Protocols: Aseptic handling and packaging procedures
Batch Documentation: Complete traceability from synthesis to delivery

What does "Research Use Only" mean?

"Research Use Only" (RUO) is a classification indicating that a product is intended exclusively for laboratory research and experimental investigation.

How are peptides shipped?
