Direct answer
Is Merit Sciences legit?
Yes, with caveats. Merit Sciences has very good assay depth across 14 complete, vendor-named ILS Laboratories reports that resolve in the laboratory’s verifier. The complete reports cover one documented batch, dated July 30–August 1, 2026, and exact strengths for 13 of 27 eligible single-vial offers. Independent customer history and public company ownership details remain limited.
COA evidenceCOA quality 8/10✓COA verified14 complete ILS Laboratories reports, including 13 compound reports with identity, purity, content, metals, PCR sterility, endotoxin and fentanyl screening.
Purity: 99.01%–99.81% across 13 compound reports; none below 98%. The water report measures benzyl-alcohol content.

Yes, with caveats. Merit Sciences’ complete ILS reports provide very good assay depth, including identity, purity, measured content and extended testing.
The main gaps are incomplete current product coverage, limited independent customer history and limited public company ownership details.
01
Independent laboratory testing
Merit Sciences publishes 14 complete, two-page reports from ILS Laboratories. We checked each printed access code in the laboratory’s official verifier. Every record names Merit Sciences and matches the submitted compound, lot, total content, purity and analysis date. The files include the laboratory’s identity and purity results, chromatograms and complete supplementary pages.
02
Results and current product coverage
Thirteen reports cover research compounds and blends, including both listed strengths of Semaglutide and Tesamorelin. These report HPLC purity of 99.01%–99.81%, measured content, identity, five heavy metals, PCR sterility, endotoxin and fentanyl screening. All printed pass/fail tests pass; endotoxin is reported as a measured value. The four blend reports identify their components and total content. Exact report strengths match 13 of the 27 eligible single-vial offers. The fourteenth report covers bacteriostatic water, including benzyl-alcohol content and pH.
03
Testing history and source documents
The complete ILS files are dated July 30 and August 1, 2026. They establish one documented batch, with the shared printed lot reference LOT2026-06-0001. The assay depth is very good, while the complete files leave 14 of 27 eligible single-vial offers without an exact report match. The vendor’s source library also has 67 merchant-written result summaries, including older batches dated from March 2025. Those pages redact the laboratory and manufacturer and provide no original laboratory file. Our report count includes the 14 complete ILS documents. Original PDF results and current laboratory-web versions are retained where metals values or blend component allocations differ.
04
Company and customer evidence
The company pages identify Merit Sciences LLC and San Antonio, Texas, with support@meritsciences.com as the public contact. The domain registration record dates meritsciences.com to May 6, 2026. The exact-name Texas Comptroller search returned no company record on November 10. The reviewed public pages provide no named owner or street address. Searches under the exact brand and domain found no independent customer review history. Older third-party directory descriptions reflect an earlier version of the store and do not establish customer experiences.
