Quick take
Nationwide Peptides, run by National Science Labs, LLC in Sevierville, Tennessee, posts Freedom Diagnostics COA PDFs for about 90 product listings, most with a batch number and test date. It names mass spec as a test method, but the listings show purity only, and some batch fields are blank. Its shipping and refund terms, including refunds for unopened returns, are clearly written.
The seven checks
| Independent lab testing | Yes | The COA page names Freedom Diagnostics Testing as the lab and links a PDF report for each listing, with the lab's lookup for verification. |
|---|---|---|
| Batch-specific COAs | Partly | Most listings show a batch number and test date, but some batch fields are blank and a few entries show garbled data. |
| Identity confirmed by mass spec | Partly | HPLC and LC-MS are named as methods, but the listings show purity only, so identity results must be checked in each PDF. |
| Research-use labeling | Yes | Research-use and not-for-human-use notices appear throughout, and no dosing content or effect claims were seen. |
| Age and use confirmation | Yes | A gate before product pages asks visitors to confirm they are 21 or older with a bona fide research purpose. |
| Clear shipping and refund terms | Yes | Separate shipping and refund pages cover cut-offs, delivery times, unopened returns and damage claims. |
| Business transparency | Yes | National Science Labs, LLC lists a Sevierville street address, phone numbers, support hours and terms. |
Nationwide Peptides is run by National Science Labs, LLC, which lists a street address in Sevierville, Tennessee. It sells freeze-dried research peptides to US addresses and describes itself as a chemical supplier, not a compounding pharmacy or outsourcing facility.
We looked at the homepage, the shop, the COA page, the FAQ, a gated product page and the shipping and refund policies. The store pairs a large public COA library from a named lab with clear refund terms, though its identity data is less visible than its purity data.
Who Nationwide Peptides is and what the catalog covers
No founding year or staff names are given. The site says its peptides are made in US-registered facilities with chain-of-custody records, without naming the maker.
The shop runs to six pages of about a dozen products each. It covers single peptides such as BPC-157, Semax, Selank, SS-31, MOTS-C, GHK-Cu and Tesamorelin, blends such as CJC-1295 with Ipamorelin, GLP-1 class compounds under shorthand names, and non-peptide items such as NAD+, glutathione and L-carnitine. Prices seen ran from about $29 to $199, with several sizes for many products.
Freedom Diagnostics COAs and what they show
The COA page names Freedom Diagnostics Testing as the independent lab and lists roughly 90 product and strength entries. Each links to a downloadable PDF and shows a purity figure, and most add a batch number and test date. Examples include a 5 mg BPC-157 batch tested in January 2026 at about 98.8% and a 10 mg CJC-1295 and Ipamorelin batch tested in June 2026 at about 99.96%. To verify a report, buyers enter its accession number in the lab's own lookup tool.
The FAQ says testing uses HPLC for purity and mass spectrometry for identity, and that reports include chromatograms. The listings themselves show purity only, so identity results need to be read in each PDF. Some batch fields are blank, and at least one entry shows garbled purity data. Purity also varies more than the 99% goal suggests, with one listed DSIP batch at about 95.7%.
Labeling and purchase checks
Research-use notices appear in a dedicated homepage section, the footer, the FAQ and the gate page, each stating that the products are not for human use. We saw no dosing content or effect claims. The FAQ names suitable solvents and storage windows but gives no amounts.
Product pages sit behind a gate that asks visitors to confirm they are at least 21 and have a bona fide research purpose. The answer is remembered for a year.
Ordering, shipping, refunds and support
Payment is by Visa, Mastercard or PayPal. Orders placed before noon Eastern usually ship the same business day from a domestic facility by UPS, USPS or FedEx, with three to five days in transit and four to seven days in all. Shipping is free on orders over $200, and only US addresses are served. Cold packs are not mentioned.
The refund policy is more generous than most. Unopened, untampered items can be sent back to the Sevierville address for a full refund to the original payment method. Damaged, defective or incorrect items are replaced or refunded once a claim with photos is approved. Opened items are not refundable, exchanges are not offered and lost parcels are not addressed. Support is by phone and email on weekdays, with replies usually within a day.
Verdict: who Nationwide Peptides suits
Nationwide Peptides suits US labs that want a named lab's report for nearly every listing, card payment, a street address and a return option for unopened stock. It is a weaker fit for labs that need identity data summarized up front or shipping outside the US.
Before ordering:
- Open the PDF for your product and strength, and check that it includes a mass spec identity result.
- Match the batch number on your vial to the report, and confirm it through the lab's lookup.
- Ask support about any entry with a blank batch field before relying on it.
