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

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.

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

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

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

All orders are shipped with research-grade handling protocols:

  • Packaging: Insulated containers with cold packs when required
  • Carriers: USPS Priority Mail
  • Processing: Orders placed before 12 PM EST ship same business day
  • Tracking: Full tracking information provided via email

At House of Compounds, product quality, consistency, and research integrity are at the core of everything we do.
