Evidence summary

NextSelf Labs COAs and evidence

A substantial testing record

NextSelf’s report library contains 59 complete reports dated June 7–October 8, 2026: 32 from Freedom Diagnostics Testing and 27 from ILS Laboratories. We verified the reports against their issuing laboratories. Sixteen reports are dated June, 13 July, 25 September and five October, showing repeat testing across the period; BPC-157, Selank, SS-31 and Thymosin A-1 each have repeat reports. An example is the Freedom GHK-Cu 50 mg report.

What the reports measure

The 58 compound and blend reports document identity, purity and measured content; 26 ILS reports additionally screen for fentanyl. The water report uses a PCR microbial screen. Numerical purity ranges from 97.69% to 99.96%, with one of 58 below 98%. The DSIP report records 97.69%, above the laboratory’s printed 95% limit. Exact compound, formulation and strength reports match 27 of the 40 eligible offers reviewed. Other sizes can use a related report when the compound and formulation match; mist listings do not inherit vial reports.

Company and operator

NextSelf lists a Cleveland Heights, Ohio mailing address and support email in its terms. A NEXTSELF trademark application filed July 9, 2026 names NEXTSELF, LTD., an Ohio limited liability company, at that same address. The domain was registered April 6, 2026. Peptide Source Review reports that the person who submitted NextSelf and GhostLabz said they run both.

Customer reputation

Independent feedback for the exact store is still limited. Peptide Scanner’s review reported no external customer reviews in its November 2026 check. Its assessment and its smaller certificate sample are separate from our 59-report review.

Shipping, payment and returns

The store ships within the United States and advertises free shipping over $200. A $39.99 order quoted UPS Ground $9.98, 2nd Day Air $16 and Next Day Air $49.99, with optional Route protection separate. The checkout listed credit or debit cards and a Cash App / cryptocurrency option displaying USDC and USDT. Processing time and delivery estimates were not stated. Its refund policy says sales are final, with remedies for damaged or incorrect deliveries, confirmed loss and qualifying independent testing discrepancies.
