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

After reconstitution:

  • Store at 36–46°F and use within 4 weeks
  • Avoid repeated freeze-thaw cycles to preserve peptide integrity

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.

These products are not intended for human or veterinary use, have not been evaluated by the FDA for safety or efficacy, and must not be used for diagnostic, therapeutic, or any other clinical purpose.

These statements have not been evaluated by the Food and Drug Administration. These products are not intended to diagnose, treat, cure, or prevent any disease.

Orders are generally processed and transferred to our shipping partners within 1–2 business days (Monday through Friday, excluding U.S. holidays). Orders placed and paid by 12:00 PM PST on a business day typically ship the same day. Orders placed after this cutoff, or on weekends and holidays, ship the next business day.

  • Carriers: USPS, UPS, and FedEx
  • Free Shipping: Available on orders over $400.00 (pre-tax/pre-shipping total)
  • Expedited Options: USPS Priority, FedEx 2-Day, FedEx Overnight, FedEx Overnight with Signature, and FedEx Saturday Delivery (orders placed before noon PST on Friday)
  • Tracking: A shipping confirmation email with your tracking number is sent upon dispatch — check your spam folder if not received
  • Insurance: Shipping insurance is included on all orders to protect against loss or damage in transit
Note: Once a package leaves our facility it is under the carrier's responsibility. Occasional product backorders may extend preparation time.

Lost Packages: A minimum waiting period of 20 business days from the carrier's initial pick-up date must pass before we can officially declare a package lost and file an insurance claim.

Damaged Shipments: If your order arrives damaged, you must contact us within 3 calendar days of delivery. Our insurance provider requires clear photographs of both the damaged product and the internal and external shipping packaging to initiate a claim.

Theft: Our insurance policy does not cover packages confirmed as delivered by the carrier but subsequently stolen from the delivery location. We are not responsible for losses due to theft after delivery confirmation.

To protect order accuracy, all packages are photographed with their shipping label prior to dispatch. Signature confirmation is required for high-value orders.

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
