Qureshi Labs
LimitedLast updated September 1, 2026
Qureshi publicly states that every product is independently tested, that every batch has a third-party COA, and that testing verifies identity and purity. The reviewed public evidence supports those claims far better than the deeper panels.
Documented strengths
- ✓Clear public statements: "documented every batch" and "99%+ identity, independently confirmed."
- ✓A COA is stated to be provided for each batch.
Limitations in this review
- —The public COA page in the current crawl does not expose the detailed, searchable lot records seen at PSPeptides, Rejuven8, Panda, Honest or American Peptides.
- —Visible evidence is much stronger for identity and purity claims than for measured vial content, endotoxin, sterility or heavy metals.
- —Included as a lower-transparency comparison point, not as a quality judgment about the material itself.
