Quick take
Natty Plus Labs publishes Janoshik reports for nine peptides, each with a batch number, task number and verification key, which is better batch paperwork than many small stores show. The reports cover HPLC purity only, its six SARMs are sold in solution with no reports, and its shipping and returns page could not be read. Contact is by email only, with no business address.
The seven checks
| Independent lab testing | Yes | Each peptide entry names Janoshik Analytical and links the full report on the lab's site, with a verification key. |
|---|---|---|
| Batch-specific COAs | Partly | Nine peptides have batch-numbered reports dated March 2026, but the six SARMs have no reports and a few catalog items are not covered. |
| Identity confirmed by mass spec | No | The reports listed are HPLC purity tests, with no mass spec identity result. |
| Research-use labeling | Partly | Research-only notices are clear and no effect claims were seen, but SARMs are sold as liquids in solution alongside vials. |
| Age and use confirmation | Partly | Age terms appear only in written policies, which disagree: the terms say 21 and the research disclaimer says 18. |
| Clear shipping and refund terms | Partly | A Shipping & Returns page is linked but could not be read when we looked, and no refund terms appear elsewhere. |
| Business transparency | Partly | Natty Plus Labs LLC gives support, wholesale and affiliate emails and full terms, but no phone number or business address. |
Natty Plus Labs is the store of Natty Plus Labs LLC, whose terms point to California law. It sells a short list of research peptides in 3 mL vials, plus a separate group of SARMs, and states that everything is for laboratory research only and not for human, medical or veterinary use.
We looked at the homepage, the product list, the COA page, the about page, the terms and the research disclaimer. Two pages, including Shipping & Returns, returned errors when we tried to read them. The store's strength is its Janoshik paperwork for peptides; its gaps are identity data, the SARM range and thin policies.
Who Natty Plus Labs is and what it sells
No founding year, owners or street address are given. The about page says the company does no in-house testing and relies on an outside lab for every batch.
The product list showed 18 items. Twelve are peptides or supplies, including BPC-157, TB-500, GHK-Cu, Ipamorelin, Semax, Selank, CJC-1295 without DAC, NAD+, one GLP-1 class compound and bacteriostatic water. Six are SARMs listed as supplied in solution, two of them out of stock. Prices ran from about $38 to $80.
Janoshik batch reports for peptides
The COA page lists nine peptides. Each card shows the vial size, a batch number in the store's format, a Janoshik task number, the analysis date, an HPLC purity figure and a verification key, with a link to the full report on Janoshik's site. The BPC-157 5 mg batch, for example, was analyzed in March 2026 at about 99.05%, and the other listed batches ran up to about 99.95%.
Three gaps stand out:
- No mass spec identity result appears, so the reports show purity but not a measured mass.
- The six SARMs carry no third-party reports, which the product list states plainly.
- The page header says results are published without request, while the footer says COAs are available on request.
Because each card carries a verification key, a buyer can check the report on Janoshik's verification page and compare the batch number with the vial label.
Labeling and purchase checks
Research-use notices appear in the footer, the terms and a separate research disclaimer, which bars personal use and administration to people or animals. We saw no dosing content or effect claims. The SARMs, though, are sold as liquids in solution next to the vial range, a format that falls short of strict research-use labeling.
No age gate appeared. The terms require buyers to be 21 or older, while the research disclaimer gives 18 as the minimum and treats placing an order as confirmation.
Ordering, shipping, refunds and support
The site says orders are packed and shipped in the USA, usually within 24 to 48 hours. Carriers, delivery times, costs and cold-pack use are not stated on the pages we could read. Payment methods are not listed; the terms say only that prices are in US dollars and that payment must clear before an order ships.
Refund and reship terms sit on a Shipping & Returns page that returned an error when we tried to read it, and the terms and disclaimer do not cover them. The terms let the store refuse or cancel any order and cap its liability at the order price. Support, wholesale and affiliate contacts are separate email addresses; there is no phone number.
Verdict: who Natty Plus Labs suits
Natty Plus Labs suits labs that want a small peptide range with batch-level Janoshik reports they can verify themselves. It is a weak fit for labs that need mass spec identity data, written refund terms before ordering, or reports for every item in the catalog.
Before ordering:
- Check the batch on your vial against the COA page, and confirm it with Janoshik's verification tool.
- Ask support for the current shipping and refund terms in writing.
- Ask whether identity testing is available for your batch.

Questions
Is Natty Plus Labs legit?
Natty Plus Labs LLC publishes Janoshik reports with batch numbers and verification keys for its peptides, plus written terms and a research disclaimer, but no business address, phone number or readable refund policy. No outside reviewer can vouch for a single order, so match the batch number on your vial to its report and confirm the report with Janoshik.
Which lab tests Natty Plus Labs products?
The COA page names Janoshik Analytical for every peptide listed and links each report on Janoshik's site. The SARMs have no published reports.
What is the Natty Plus Labs refund policy?
Refund terms sit on a Shipping & Returns page that could not be read when we looked, and the other policies do not cover them. Ask support for the current terms in writing before ordering.
