Quick take
Nura Peptide, run by Nura Systems LLC in Parkland, Florida, posts a large library of lot-numbered Freedom Diagnostics certificates, many with endotoxin and microbial results. Its shipping and return terms are clearly written. The catalog also includes capsule products and a liquid item, and the 21+ confirmation sits in the research-use terms rather than a gate.
The seven checks
| Independent lab testing | Yes | Freedom Diagnostics Testing is named on every certificate, and each record links to the original lab PDF with an accession number. |
|---|---|---|
| Batch-specific COAs | Yes | The library holds 122 lot-numbered records dated from September 2025 to October 2026, and product listings show their current lot. |
| Identity confirmed by mass spec | Partly | LC-MS identity is reported as confirmed on each certificate, but observed and expected masses are not shown on the record pages. |
| Research-use labeling | No | Research-use-only notices are clear and the learning pages stay analytical, but capsule products and a 30 ml liquid are sold alongside vials. |
| Age and use confirmation | Partly | A 21+ purchaser certification applies on submitting an order under the research-use terms; no entry gate or checkbox was seen. |
| Clear shipping and refund terms | Yes | A combined shipping and returns page sets out cut-off times, carriers, rates, a 30-day unopened return window and a 48-hour damage claim window. |
| Business transparency | Yes | Nura Systems LLC lists a Parkland, Florida address, a phone number, a contact page and written terms. |
Nura Peptide is operated by Nura Systems LLC, which lists an address on North University Drive in Parkland, Florida, and a phone number on its site. It sells lyophilized research peptides, blends and laboratory diluents, and it frames every product for in vitro research by qualified buyers aged 21 or older. No founding date is given.
Its testing library is the most detailed part of the site. We looked at the homepage, shop, COA library, a single certificate record, the learning pages, the research-use policy and the shipping and returns page.
What the Nura Peptide catalog covers
The shop lists 43 items. Most are single peptides and blends in vials, such as BPC-157, TB-500, GHK-Cu, Tesamorelin, MOTS-c, NAD+, Semax and Selank, along with GLP-class compounds sold under codes such as GLP-3R and GLP-2T. Bacteriostatic water, buffered saline and dilute acetic acid are also offered. Starting prices run from about $10 for water to about $150.
The range also includes four capsule products and a 30 ml liquid item. Their listings carry no usage claims, but capsules and liquids are not standard formats for laboratory reference material, which is a gap in an otherwise research-focused catalog.
Freedom Diagnostics certificates and lot records
Every certificate in the COA library comes from Freedom Diagnostics Testing. The library lists 122 records, dated from September 2025 to October 2026, each tied to a lot code such as BPC-102026-1. Product listings show the lot currently offered.
A record page sets out the results in text. The BPC-157 lot BPC-092026-1, for example, shows:
- A lab accession number and a release date of September 16, 2026.
- HPLC purity of 99.81% and LC-MS identity marked as confirmed.
- Net content of 13.07 mg against a 10 mg label.
- Passing endotoxin and PCR microbial results, with a link to the original PDF.
Coverage varies. The site says 43 records report all eight tests, 80 report endotoxin and 47 report heavy metals, and some capsule records give no purity figure. Observed and expected masses are not shown on the record pages, so buyers should open the PDF. Posted purity runs from 98.62% to 99.96%, so the lowest lot sits below the stated 99% standard.
Labeling and purchase checks
Research-use notices are clear across the shop and certificate pages, which state the products are for in vitro laboratory and analytical use only and not for human or veterinary use. The learning library sticks to COA reading, HPLC and mass spec, sequences and storage, with no usage content.
The 21+ check is weaker. The research-use policy says buyers certify they are at least 21 and qualified simply by submitting an order. The footer says a research account is needed to browse and order, yet prices were visible without signing in and no entry gate was seen.
Shipping, returns and support
Orders placed before 3:00 PM ET on a weekday ship the same day. FedEx 2-day and UPS Ground are the main services, with USPS for P.O. boxes and Puerto Rico. Insured 2nd Day Air costs $12 and is free on product totals from $250; overnight costs $60 on every order. The page says lyophilized products travel without refrigeration and that vials are barcode-scanned before dispatch. The ship-from location is not stated.
Return terms in brief:
- Unopened products can be returned within 30 days after contacting support.
- Damaged or wrong items must be reported within 48 hours with photos of the slip, products and label.
- Lost parcels are reviewed after 7 business days without tracking movement.
- Refunds follow inspection of returned goods, with no timeline given.
Support is by phone and a contact page. Payment methods were not listed on the pages reviewed.
Verdict: who it suits and what to check
Nura Peptide suits US labs that value named-lab certificates with contamination screens and want a broad catalog. Its testing records are more complete than most, and its shipping terms are specific. Labs with strict format rules should note the capsule and liquid items.
Before ordering, confirm the lot on the listing matches a posted record, open the PDF for the mass spec result, and check which tests that lot actually covers.
