Is NextSelf Labs legit?
NextSelf Labs scores 6.26 out of 10 (Fair, #55 of 100) as of November 6, 2026 and passes our testing gate: 29 of the 32 products we score carry a certificate, 29 confirmed with the issuing lab (labs we grade A to B+). Its strongest area is lab testing (7.1/10); its weakest is operating history (1.4/10), with about seven months of records.
On lab evidence, the heaviest-weighted factor, NextSelf Labs has independently verified third-party COAs, with COA work on record from ILS Laboratories, Freedom Diagnostics Testing. We hold 46 lot certificates in all. Its lowest price per milligram in our data is on Glutathione (see the table below).
How this score was calculated
Every point below follows the published tables in our methodology, with the policy wording we scored and a link to where we read it. Evidence last checked November 6, 2026. Lab credibility is worked product by product from the certificates on file.
Lab credibility7.1/10
Each carried product (lab supplies excluded) is scored from the certificate on file for it, on the published lab rubric: 3 for a published certificate, then points for the laboratory, the verification key, the tests on the certificate and its purity, held to 0 to 10. A certificate that is self-issued, names no laboratory, or comes from a laboratory whose independence is not established scores a flat 2.0; a product with no certificate, a certificate the laboratory’s own record fails, or a posted copy that differs materially from the laboratory’s copy scores 0. Calculated on , the day this page was built; the date each certificate was tested is shown on its row.

No certificate on file for this product: scores 0, counted at 0.5 weight because it is not one of the core products.
Weighted mean of 32 products (3 non-core products without a certificate counted at half weight): 230.5 ÷ 30.5 = 7.557.
- −0.20LOT Lot numbers that do not identify a single batch (cap −0.2): lot label NS-2609-026 is printed on the Tesamorelin 20mg (COA-2026-957272) and Thymosin Alpha-1 10mg (COA-2026-957033) certificates, both scored, and on Bac Water 3mL (COA-2026-957271), with the laboratory records carrying the same label; and 17 posted ILS copies print an NS-2609 lot label where the laboratory record for the same access code prints a GL-2609 label. One LOT adjustment covers both (owner ruling 2026-11-06; the rule is capped at -0.2)
- −0.30CLAIM Claims the certificates do not support (cap −0.3; −0.30 entered, held to the cap): test panel: every product page says 'Identification: Mass spectrometry confirmed' and the home page says identity is confirmed using HPLC and mass spectrometry, while the ILS certificates report identity by HPLC retention time against a reference standard, with no mass spectrum; purity: the landing page says every batch is tested to confirm purity of no less than 99%, while five scored certificates read below 99% (DSIP 97.69%, GLOW 98.17%, KPV 98.41%, retatrutide 20mg 98.85%, CJC/Ipamorelin 98.98%); accreditation: product pages carry the badge '4X Tested - ISO 17025', while ILS Laboratories' own site says 'Peptide testing is not within any accreditation scope and is provided for Research Use Only', and Freedom Diagnostics Testing, the only laboratory on five badged pages, publishes no accreditation
7.557 − 0.500 = 7.057, rounded to 0.1: 7.1/10.
Testing gate: 29 of 32 products have a certificate from a directory laboratory (not tier D, not self-issued) with the key confirmed at the laboratory. That is at least half, so the vendor counts as third-party tested and no cap applies.

We compared NextSelf Labs’s current single-vial prices on 32 products, each matched to the same product and milligrams per vial, with the median price of the other vendors. Its typical price (the median ratio across those products) is 2% above the market median (ratio 1.02), which the published scale maps to 6.9/10. checked
Operating history1.4/10
Counted from April 6, 2026, the earliest dated evidence of this business operating: 7 months as of November 6, 2026, which the published table maps to 1.4/10.
The site names no operating company, so no registry start could be used. The store domain nextselflabs.com was registered 2026-04-06 (RDAP) and no earlier use was found; the home page is dated 2026-05-04, the earliest certificate was received by the laboratory on 2026-06-03, and the first archived capture is 2026-10-13. The submitter says the brand is run with GhostLabz, whose domain dates from 2025-11-29; that is not used because no shared operating company is named or recorded.

Editor’s notes
NextSelf Labs sells research peptides from nextselflabs.com and ships within the United States. The site names no company and no person. It gives a Cleveland Heights, Ohio address, where a local business offers virtual mailboxes, and no phone number; its hours are in Mountain Time and its terms, dated May 2026, follow Arizona law. The domain was registered in April 2026, and the earliest certificate we hold was received by the laboratory in June 2026. Of the 32 catalogue products we list, 29 have a posted certificate; Ovagen, LL-37 and VIP do not. We scored the newest certificate for each: 24 from ILS Laboratories and 5 from Freedom Diagnostics Testing. All 59 certificates posted on the store were found at the issuing laboratory. Purity on the scored certificates runs from 97.69% to 99.93%, none includes an endotoxin or sterility result, and ILS confirms identity by HPLC retention time, not mass spectrometry. NextSelf's ILS reports match reports issued to GhostLabz, another store: 25 of its 26 ILS peptide reports have a GhostLabz report with the same dates, results and chromatogram. On 17 reports the copy on the store carries an NS lot label where the laboratory's record carries a GL label. The person who submitted both brands told us they run both; no public record names a shared company. One lot label, NS-2609-026, also appears on the Tesamorelin and Thymosin Alpha-1 certificates. The site says identity is confirmed by mass spectrometry on every batch, that every batch tests at no less than 99% and that products are tested to ISO 17025. The ILS reports show identity by retention time, five scored certificates read below 99%, and ILS's own site says peptide testing is not within any accreditation scope, while Freedom Diagnostics Testing publishes no accreditation. Tirzepatide and retatrutide are sold as NS-2TZ and NS-3RT, and their pages do not name the compound. All sales are final. Damaged, wrong and lost orders are replaced or refunded, with a 7-day window for damage and wrong items, though the terms and the refund policy differ on returns. The site shows card logos and a free-shipping threshold; it states no dispatch time and no tracking. In November 2026 prices sat close to the market median.
