Direct answer

Is Research Labs legit?

Yes. Research Labs earns 8.5/10. Its complete Ethos Analytics archive contains 59 reports across 84 pages, all naming Research Labs and reporting identity and measured content. Thirty-seven include endotoxin testing, 25 include heavy-metals testing and 16 include microbial testing. Forty-three print purity above 99%. Six reports match official laboratory records; the other 53 are complete vendor files dated before the public index. The catalog has 63 offers, with an exact-strength certificate for 58.

Evidence summary

Research Labs COAs and evidence

Research Labs publishes a complete, consistently documented Ethos Analytics archive and an exact-strength certificate for 58 of its 63 offers. The six records already in the laboratory's public index match byte for byte. The other 53 are not failed tests: their dates precede the portal, and Ethos says pre-launch certificates may not yet be searchable. They remain neutral View COA files until Ethos confirms or indexes them.

The company identifies its LLC, Texas address and support channels. Checkout offers US and Puerto Rico destinations, a $150 free-delivery threshold and a 14-day returns window; the shipping page describes all 50 states. Buyers should compare the exact strength on the product row with the linked report and confirm the final checkout total.

01

Complete Ethos Analytics archive

PeptidePrices reviewed all 59 Research Labs certificates: 84 pages, June 18 to September 18, 2026, all issued by Ethos Analytics. Six records match the laboratory's public index byte for byte: Retatrutide 20 mg and 30 mg, GHK-Cu 50 mg, NAD+ 500 mg, Sermorelin 10 mg and Kisspeptin 10 mg. The other 53 are complete vendor PDFs with the same Ethos template, client line, sample ID and director signature. Their June and August dates precede the public index; Ethos tells visitors that certificates issued before the portal's launch may not yet be searchable. These 53 reports open as complete checked files with neutral View COA controls.

02

Test panels and results

The archive includes 37 reports with endotoxin testing, 25 with heavy-metals testing and 16 with microbial testing. Sixteen capsule and spray reports combine identity and measured content with heavy metals and microbial panels. Twenty-eight June vial reports add endotoxin testing to identity, purity and content; nine August vial reports include both endotoxin and metals. The remaining six reports cover identity, purity and content. Every reported panel passes its printed criteria. Forty-three reports print purity as >99%, a reporting threshold rather than an exact percentage. Measured content runs from 100.4% to 108.1% of label. One historical GLP-3 15 mg report has no current 15 mg offer and remains in the library.

03

Exact catalog coverage

The live catalog has 63 offers across 37 compounds. Fifty-eight offers have an exact-strength certificate. Five do not: GHK-Cu capsules 2 mg x 60, CJC-1295 No DAC 5 mg, Ipamorelin 10 mg, Sermorelin 5 mg and Tesamorelin 5 mg. The GHK-Cu capsules page links the 50 mg vial report, which is not an exact match; the other four have no report at their listed strength.
