This research peptides FAQ collects the questions laboratories actually ask before, during and after an order — what research peptides are, what a certificate proves, how purity is guaranteed, and how shipping, storage, returns and wholesale work. Each answer is written in plain language and cross-linked to the page where the full detail lives, starting with the Shop catalog and the Lab Reports archive.

Research Peptides FAQ: The Questions Researchers Ask

• Q: What are research peptides?
  Research peptides are short chains of amino acids synthesized for laboratory study — signaling molecules, growth factors and metabolic modulators examined in vitro and in approved animal models. Every product in the Shop is furnished for laboratory research use only, never for human or veterinary use. The What Are Research Peptides? guide explains the science in more depth.
• Q: Why must these be sold “for research use only”?
  Unapproved peptide compounds may only legally be supplied for legitimate research purposes. A vendor that gives human dosing guidance breaks the rules that keep this market available — and that is a vendor you cannot trust. PeptideLabNova labels every vial, publishes the Terms & Compliance page, and never advises on human use.
• Q: What is a COA and why does it matter?
  A Certificate of Analysis is a lab report from an ISO 17025-qualified third-party laboratory for one specific batch, showing HPLC purity, mass-spectrometry identity, net peptide content, testing laboratory and date. It converts “trust me” into “verify me”. Ours are published for every batch on Lab Reports, and the How to Read a COA guide decodes each figure.
• Q: What purity do you guarantee?
  98% or better by third-party HPLC, with mass-spectrometry identity confirmation, batch by batch. The COA for your exact batch is downloadable before you buy, and every batch record stays in the Lab Reports archive permanently. Any batch below 98% is destroyed, never shipped.
• Q: How do you price below every major vendor?
  Direct sourcing and lean operations. We publish per-milligram prices openly and still third-party test every batch. Compare our $/mg on any product page, then check whether the cheaper-looking vendor publishes batch-specific COAs — most cannot, and that difference is the real price.
• Q: How are peptides shipped?
  Vacuum-sealed and discreet, handed to USPS or UPS within 24 business hours with automatic tracking by email. Lyophilized powders are transit-stable at ambient temperature; refrigerate at 2–8 °C on arrival. Carriers, packaging and rates are detailed on the Shipping & Returns page.
• Q: How should I store peptides?
  Powder: refrigerate at 2–8 °C, or hold at −20 °C for long-term storage past six months, sealed and away from light and temperature swings. Reconstituted: keep at 2–8 °C and use within your protocol window, avoiding freeze-thaw. The full Reconstitution & Storage guide covers each stage.
• Q: What is your return policy?
  Unopened, sealed vials can be returned within 30 days of delivery for a full refund, and damaged shipments are replaced free if photo-documented within 48 hours. Opened vials cannot be returned for integrity reasons. The written terms live on Shipping & Returns and the Refund Policy.
• Q: Do you ship internationally?
  Currently within the United States only. If you are outside the US, Contact Us and we will add you to the notification list and email you the moment your country opens. No spam — a single email, when the news is real.
• Q: What payment methods do you accept?
  Major credit and debit cards at checkout, plus [LIST YOURS: major cards, Zelle, crypto, etc. — set this up with your payment processor before launch.] All payments are processed by our payment processor, and full card numbers are never stored on our servers. See the Privacy Policy for the detail.
• Q: Do you offer wholesale pricing?
  Yes — any five or more vials, mixed freely across categories, switches volume pricing on automatically in the cart, and 20+ vials unlocks the deepest tier. Standing orders, custom pricing and institutional purchasing go through the Contact Us form with a Wholesale Inquiry subject.
• Q: How do I get the COA for the batch I bought?
  Every batch certificate is on the Lab Reports page, keyed by batch number, and rows appear the moment quality control releases a batch. If you cannot find yours, use the COA request form there and we reply within one business day.

Questions This FAQ Answers in One Line

If your question is not on this research peptides FAQ, the Contact Us form is the next stop — a real person answers within 24 business hours, usually faster. For COA requests, the Lab Reports archive and its request form are the fastest path.

Every answer on this research peptides FAQ is written against the documents linked here — the Lab Reports library and the How to Read a COA guide — rather than against vendor folklore. If the question you need is not in the list above, send it through the Contact Us form and a person from the lab-support desk replies; when there is no honest answer, we say exactly that instead of inventing one.
