The August 2026 ranking cycle incorporates six new laboratory reports, two resolved consumer-report cases, and refreshed fulfillment testing across all twelve indexed companies.
Apex Peptides extends its lead at 92 — its third consecutive cycle at the top — on the strength of a perfect testing record and newly published manufacturing disclosures. BioRegen Research climbs to 85 after posting the cycle’s highest single purity result.
The cycle’s largest movement is negative: Cascade Research Group falls from 58 to 41 following two failed purity verifications, detailed in our June testing reports. The company remains under active review.
