We rate Essential Research Labs 6.5/10. Its verified PEPTIDEPRICES code delivers 30% off, and its 28-file COA archive provides substantial laboratory data. The printed clients are PTA, Wave Research and Eric R. Fong, so the reports are not attributed to Essential. One Freedom report also has an identity-result conflict.

Verification notes
What we reviewed, with the limits of that evidence kept explicit.
01
Certificate archive
PeptidePrices retained every file on Essential Research Labs’ public /coa page: 28 one-page certificates. Twenty-six are Freedom Diagnostics, one is BioViridian, and one is MZ Biolabs. Twenty-five Freedom official PDFs match the vendor JPEGs on client, accession, search code, lot, product, identity, purity, and measured content. Accession 2607090016, ADX10 10mg, matches those fields except sample-summary Identity: the vendor JPEG prints Confirmed and the official PDF prints Failed. The 5-Amino 30mg report 2606250155 is a one-page two-vial panel (29.80 mg and 30.21 mg, average 30.01 mg); 2607090018 is an endotoxin screen only.
Those Freedom reports name laboratory client PTA. The BioViridian Ipamorelin 10mg report, COA5558 lot LNC-201713, names Wave Research and matches the official PDF. The MZ Biolabs Tesamorelin 10mg report names Eric R. Fong, lot 2026-04-20, 99.95% and 12.27 mg; MZ has no public registry. PeptidePrices does not count those records as Essential-verified or attach them to listings.

How we rate vendors
Our quality scores are based on a weighted rubric: 40% COA practices (named third-party lab, batch linkage, public availability), 20% community reputation, 20% transparency, and 20% operations. We are independently owned; affiliate status is not a scoring factor.
PeptidePrices is independently owned and participates in Essential Research Labs's affiliate program. We may be paid for qualifying purchases through our links. Essential Research Labs cannot edit or approve this review, and the relationship does not add points to its score.
