Frequently Asked Questions

Every production batch is sampled across multiple vials and sent to an independent, ISO/IEC 17025-accredited laboratory. The lab verifies four parameters: purity (by HPLC), identity (by mass spectrometry), concentration (quantitative), and endotoxins (by LAL). Only when all four parameters pass acceptance criteria does the batch earn the Nuva Verified designation, and the full Certificate of Analysis is published to our public COA library.

A COA reports four values that matter most. Purity (the percentage of the sample that is the target compound). Identity (confirmation that the compound matches its expected molecular profile). Concentration (the measured active content). Date (when the test was performed). The Batch Number on the COA must match the batch code on your vial. If they do not match, the COA is not for your product.

Every Nuva vial ships with a QR code printed on the label. Scan it with your phone and you land on the Certificate of Analysis for that exact batch. No searching, no account login, the document your specific vial was tested against in under 30 seconds.

Locate the batch code on your vial label. Every Nuva batch code begins with “NV-” followed by an alphanumeric code. Visit our COA library and enter that exact batch code in the search bar. The matching Certificate of Analysis will appear for download. Cross-reference the batch number on the document against the code on your vial before reviewing the results.

Three things. First, we sample multiple vials from every batch, not a single vial representing an entire production run. Second, we test across four parameters including endotoxins, not just purity. Third, every COA is published publicly by batch and linked via QR code on every vial. Verification is built into the product itself, not separated from it.

Batches that fail any acceptance criterion are rejected and do not enter the catalog. Failed batches are documented internally and never released for sale.

Our Bacteriostatic Water undergoes USP 71 sterility testing in addition to standard identity and concentration verification. USP 71 is a pharmacopeial standard that goes beyond typical industry practice for BAC Water.

Our current testing partners include Freedom Analytics, Vanguard Laboratory, and Ethos Analytics (ISO/IEC 17025 accredited). The testing laboratory is named on every Certificate of Analysis we publish.

No. All Nuva products are sold strictly as research materials for in-vitro and pre-clinical laboratory research. They are not approved by the FDA, not intended for human or animal consumption, and not intended for use as a drug, food additive, cosmetic, or household chemical. By purchasing, you acknowledge you are a licensed researcher operating in a properly equipped laboratory environment.

We cannot. Nuva has no visibility into your research protocols, institutional context, or experimental design, and due to legal regulations around research compounds, we do not provide guidance on product usage outside of storage-related questions. Storage guidance is available on individual product pages and in this FAQ. For research-design and usage questions, consult the peer-reviewed literature or your institution's research lead.

Lyophilized products are peptides supplied as a freeze-dried powder in a sealed vial. They require reconstitution with a suitable solvent such as bacteriostatic water before use. Dry-fill products are pre-measured research units supplied in a dry format, ready for direct use in research protocols that require discrete fixed quantities. Liquid products are supplied pre-dissolved at a specified concentration and are ready for immediate research application. Choice of format depends on your protocol. Lyophilized offers longer shelf life, dry-fill offers pre-measured consistency, liquid eliminates a preparation step.

Lyophilized products require reconstitution with a suitable solvent before use. Bacteriostatic Water is the most common choice for research protocols because it is sterility-tested and contains 0.9% benzyl alcohol as a bacteriostatic agent. Our BAC Water goes through USP 71 sterility testing and is available in the Reconstitution category of our catalog.

N-acetylated analogs are chemically modified versions of their parent compound where an acetyl group has been added to the peptide structure. This modification can alter the compound's stability, half-life, and receptor interaction profile in research contexts. Which version is appropriate for your study depends on the specific research question. Consult the published literature for your research area.

Nuva compounds are ≥99% purity by default, measured by HPLC. Each Certificate of Analysis shows the exact purity value for that specific batch. If you receive a product whose COA shows purity below 98%, contact us. This is outside our standard and we will review.

Lyophilized peptides should be stored at -20 degrees C or below, in a dry environment away from direct light. Lyophilization removes water, which slows nearly all degradation pathways, but temperature still matters for long-term stability. Do not store lyophilized product in hot temperatures for extended periods.

Once reconstituted, peptides should be stored in single-use aliquots. Reconstituted material is far more susceptible to degradation from repeated freeze-thaw cycles, hydrolysis, and oxidation than lyophilized material. Dividing into single-use portions immediately after reconstitution is the advised storage practice.

Working solutions kept at refrigerated temperatures (2-8 degrees C) should generally be used within 30 days depending on the compound. For longer storage, the solution should be aliquoted and frozen. Refer to the product page for compound-specific guidance.

Lyophilized peptides typically carry a shelf life of YEARS when stored properly in a sealed vial. Specific shelf-life details vary by product.

Nuva air dispersal spray products are pre-mixed and can be stored at room temperature or refrigerated. They do not require reconstitution. Check the individual product for compound-specific storage details.

Yes. The $150 match-or-refund guarantee requires independent testing within 30 days of purchase and assumes proper storage throughout. Variations in test results from improperly stored material cannot be attributed to the original product, so improper storage disqualifies a guarantee claim.

Due to the nature of our products and services, we do not offer refunds, returns, or exchanges once a purchase has been completed. By placing an order, you acknowledge and agree that all purchases are non-refundable. Please review all product information, descriptions, and pricing carefully before completing your purchase. If you have any questions prior to ordering, we encourage you to contact us so we can assist you.

Yes, within 2 hours of placement, provided the order has not yet shipped. Email our support team immediately with your order number. Cancellations before shipment are subject to a 10% restocking fee (covers card-processing fees on settled transactions) if it has been longer than 2 hours. Once the order has shipped, cancellations are not accepted.

Shipped orders are non-refundable under the standard policy. In limited cases we may accept a reversal at our discretion, in which case a 10% restocking fee plus the original shipping cost will apply, and the customer is responsible for return shipping. Contact support to discuss.

Submit the product to an ISO-accredited independent laboratory for testing within 30 days of purchase. If the results do not match the COA we published for your batch, we issue a full refund plus $150 in store credit. This is the Nuva Match-or-Refund Guarantee. The customer selects the accredited laboratory. We do not require use of a Nuva-affiliated lab.

No. Exchanges are not offered. If you placed the order within the last 2 hours and it has not shipped, you can reach out to our service team for an adjustment or cancel the order and place a new order for the correct product. Once shipped, orders are non-exchangeable.

Double-check format, strength, and quantity before checkout. Product pages list the exact specifications for each variant. If the order has not shipped and you are within the 2-hour cancellation window, email support immediately. Orders that have shipped are subject to the All Sales Final policy.

Kit pricing applies automatically on every peptide, no code needed. Save 20% on a Kit of 10 – buy ten vials of the same compound and the kit price drops in at checkout. Each product page also has a featured “Kit of 10” purchase option that sets quantity to 10 in one click. Kit pricing applies at the single-product level: the tiers count your quantity of that specific compound, not your total cart.

No. Kit pricing is a per-compound discount. Five vials of Compound A plus five vials of Compound B is not a Kit of 10. It is five of one and five of the other, priced independently. This keeps the discount tied to actual bulk-per-compound purchasing, which is what the pricing is designed to reward.

Yes. Verified research institutions placing regular bulk orders can qualify for institutional pricing and invoicing with Net-15 terms. Email us with your institution name and purchasing contact to begin the approval process.
