Frequently Asked Questions — Curated Compounds
Answers to common questions about Curated Compounds research peptides and compounds, ordering, shipping, and laboratory testing.
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 through analytical testing methods. Higher purity is critical for research because impurities can interfere with experimental results and compromise the reproducibility of studies. Our Standard: All our research peptides maintain > 98% purity, verified by third-party laboratory testing and documented in our Certificates of Analysis.
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: Purity Testing: Every batch tested to verify > 98% purity Identity Confirmation: Molecular weight verification for peptide identity Third-Party Testing: Independent laboratory verification Quality Protocols: Proper 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?
All orders are shipped with research-grade handling protocols: Packaging: Insulated containers with cold packs when required Carriers: USPS Priority Mail Processing: Orders are processed and shipped promptly Tracking: Full tracking information provided via email
What is your return and refund policy?
We stand behind every product: Quality guarantee: Full replacement or refund if products don't meet stated specifications Shipping issues: Free replacement for damaged or lost shipments Unopened returns: Accepted within 30 days for Store Credit
