Frequently Asked Questions
*All products sold by Etched Research are for research use only. Not for human consumption.*
Legality and Compliance
Q: Are research peptides legal to buy in the United States?
A: Research peptides sold as research-use-only (RUO) compounds are legal to purchase for laboratory and scientific research purposes in the United States. They are not approved by the FDA for human consumption and may not be sold or marketed for that purpose. Etched Research sells all compounds strictly as research chemicals intended for in-vitro and preclinical laboratory research.
Q: What does “for research use only” mean?
A: “For research use only” means the compound is sold exclusively for laboratory investigation and scientific study, not for human or veterinary use. RUO designation is a recognized classification within the life sciences supply chain. It means the product has not been evaluated by the FDA for any human application, and the seller does not represent it as suitable for such use. Atlas operates fully within this framework across all product categories.
Q: Are these compounds controlled substances?
A: The peptides and research compounds in the Atlas catalog are not scheduled controlled substances under the DEA’s current scheduling framework. This status can change, and researchers are responsible for staying current on applicable federal and state regulations governing the compounds relevant to their work. Atlas does not ship internationally and does not ship to jurisdictions where specific compounds are restricted.
Q: Can I purchase these products for personal use?
A: Etched Research compounds are sold for research use only. They are not for human consumption, personal use, or any use outside of legitimate laboratory research. Purchases constitute the buyer’s agreement that the compounds will be used in accordance with all applicable laws and solely for research purposes.
Q: Do I need any credentials or a license to purchase?
A: Atlas does not require a license to purchase RUO compounds, consistent with standard practice for research chemical suppliers. By completing a purchase, buyers represent that the compounds will be used for lawful research purposes only. Researchers affiliated with academic or commercial laboratories are encouraged to purchase under institutional accounts where applicable.
Product Quality and Testing
Q: How do I know the purity claimed on the label is accurate?
A: Every Etched Research product is tested by an independent third-party laboratory using HPLC and mass spectrometry before shipment. The batch-specific Certificate of Analysis, downloadable from each product page, shows the exact purity percentage confirmed for the specific lot number in your order. We do not use in-house testing or self-reported purity figures.
Q: What is HPLC and why does it matter for peptide purity verification?
A: High-performance liquid chromatography (HPLC) is the analytical gold standard for confirming peptide purity. The method separates compound components by chemical affinity and quantifies each fraction, producing a chromatogram that shows the percentage of the target compound versus impurities. A purity figure without an accompanying HPLC chromatogram is unverifiable. Every Atlas COA includes the HPLC chromatogram from the testing laboratory.
Q: What does mass spectrometry confirm that HPLC does not?
A: Mass spectrometry confirms the molecular identity of a compound by measuring its exact mass. HPLC confirms purity percentage; mass spec confirms you have the right molecule. Both tests are required for complete quality verification. Atlas uses both, and both results appear on the batch-specific COA.
Q: What is the purity standard for Atlas products?
A: All Etched Research compounds are verified at greater than or equal to 99% purity via HPLC and mass spectrometry. That figure is documented on the batch-specific COA for every product and every lot.
Q: What form do the compounds ship in?
A: All Atlas peptide compounds ship as lyophilized (freeze-dried) powder in sealed vials. Lyophilization is the standard for long-term peptide stability, protecting structural integrity during storage and shipping. Compounds requiring cold chain handling are stored and shipped accordingly.
Ordering and Payment
Q: What payment methods does Atlas accept?
A: Etched Research accepts all major credit cards. Stable, consistent payment processing is a core operational commitment. We do not rely on workaround payment processors or cryptocurrency-only checkout that disappear without notice.
Q: Is your checkout secure?
A: Yes. The Atlas checkout is SSL-encrypted and processed through a PCI-compliant payment gateway. Order data is not stored on our servers beyond what is required for order fulfillment.
Q: Can I change or cancel my order after placing it?
A: Order changes and cancellations can be requested by emailing orders@etchedresearch.com. If the order has not yet shipped, we will accommodate the request. If the order has already shipped, cancellation is no longer possible, but our return policy applies.
Q: Will my order confirmation include the COA?
A: Yes. Order confirmations include a link to the batch-specific COA for every product in the order, keyed to the lot number shipped. The COA is also permanently accessible through the verification portal at etchedresearch.com/coa.
Shipping and Delivery
Q: Where does Atlas ship?
A: Etched Research ships domestically within the United States only. We do not offer international shipping at this time.
Q: How is the package labeled?
A: Orders ship in generic, discreet packaging via USPS. There is no indication of contents on the exterior of the package. The return address reflects Etched Research’ US address.
Q: How long does shipping take?
A: Most orders ship within one to two business days of placement. Standard USPS delivery is typically two to five business days from ship date, depending on destination. Tracking information is provided with every shipment.
Q: Are compounds kept cold during shipping?
A: Lyophilized peptides are stable at ambient temperature for short transit periods. Compounds with specific cold chain requirements are shipped with appropriate cold packs. Storage instructions are included in every shipment and reflected in the product specifications on each product page.
Storage and Reconstitution
Q: How should I store lyophilized peptides?
A: Lyophilized peptides should be stored at -20 degrees Celsius until reconstitution. Once reconstituted, compounds should be stored at 4 degrees Celsius and used within 30 days. Avoid repeated freeze-thaw cycles, which degrade compound integrity. Specific storage instructions are listed on each product page and included with every shipment.
Q: What solvent is used to reconstitute research peptides?
A: The appropriate reconstitution solvent depends on the specific compound. Bacteriostatic water is standard for most peptides intended for laboratory research requiring extended sterile storage. Sterile water is used for compounds that will be used immediately. Solvent recommendations for each compound are documented in the Atlas reconstitution guide, available at etchedresearch.com/reconstitution-guide.
Q: How do I calculate the research concentration after reconstitution?
A: Research concentration is calculated based on the mass of lyophilized compound in the vial divided by the volume of solvent added. For example, a 5mg vial reconstituted with 2mL of bacteriostatic water yields a concentration of 2.5mg/mL. The Atlas peptide calculator at etchedresearch.com/calculator automates this calculation for any vial size and reconstitution volume.
Q: Does reconstitution affect purity or compound integrity?
A: Reconstitution does not affect the verified purity of the compound, provided the appropriate solvent is used and handling is consistent with standard laboratory practice. The purity reflected on the COA was measured on the lyophilized form. Proper reconstitution preserves that compound in solution. Exposure to heat, repeated agitation, or incompatible solvents can degrade the compound after reconstitution.
Company and Trust
Q: Is Etched Research a real company?
A: Yes. Etched Research is a US-based operation with real team members, a verified business address, and a monitored contact email at orders@etchedresearch.com. We are not an anonymous dropshipper or a reseller of unverified foreign raw material. Orders are fulfilled. COAs are real and batch-specific. Emails are answered by people.
Q: What happened to Peptide Sciences, Amino Asylum, and Paradigm Peptides?
A: Several major research peptide vendors closed or were effectively shut down between 2025 and 2026, including Peptide Sciences, Amino Asylum, Paradigm Peptides, and Science.bio. Etched Research was built specifically in response to that market collapse, with the operational infrastructure and testing rigor required to be a long-term, dependable supplier. We understand the abandonment anxiety that followed those closures. Stability, transparency, and verifiable quality are the three things Atlas was designed to deliver.
Q: How do I verify an Atlas COA is legitimate?
A: Every Atlas COA includes the issuing laboratory name, a unique batch number, the test date, the compound name and molecular weight, the HPLC chromatogram, the mass spec result, and the confirmed purity percentage. You can cross-reference the batch number against your order confirmation at etchedresearch.com/coa. If any detail on a COA you receive does not match what is listed there, contact orders@etchedresearch.com immediately.
