Frequently Asked Questions

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

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 (≥99%), lyophilized form for stability, accompanied by Certificates of Analysis (COA), and manufactured under strict quality control protocols.

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

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

We supply research-grade peptides to:

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

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