01
Independent laboratory testing
Peptixa publishes eight current-hub reports and a ninth historical NAD+ image in its public media library. All nine one-page reports match specific Chromate records naming Peptixa Labs and showing its branded sample vials. Analysis took place June 16–17, 2026; the reports were produced June 17–25. They test identity, purity and content by HPLC with UV detection. The reviewed files contain no sterility, endotoxin or heavy-metals results, despite the homepage’s broader testing statement.
02
Current products and exact certificates
The six compared offers are Tesamorelin 10 mg, NAD+ 1000 mg, MOTS-c 40 mg, KPV 10 mg, Wolverine 20 mg and KLOW 80 mg. Exact reports cover Tesamorelin, KPV, Wolverine and KLOW. MOTS-c has no recovered report. The current COA hub says NAD+ documentation is coming soon, so its historical report remains separate from the current product. Peptide and blend purity runs from 98.511% to 99.936% across eight reports, with no result below 98%.
03
GLOW and NAD+ findings
Chromate report 36436 identifies the tested sample as GLOW: GHK-Cu 50 mg, BPC-157 10 mg and Ac-SDKP 10 mg. The homepage names TB-500 as the third component, while the product page directs readers to the applicable lot COA. The report measured BPC-157 at 8.744 mg and Ac-SDKP at 8.932 mg, or 12.6% and 10.7% below their 10 mg labels. KLOW’s TB-500 measured 11.14 mg against 10 mg. The historical NAD+ report measured 92.025% purity against a >90% criterion and is marked Conforms.
