Woosh

Woosh's strength is verifiable testing on the compounds that matter most. Every product page links a batch-specific Certificate of Analysis from Freedom Diagnostics — a recognized third-party lab — covering LC-MS identity, HPLC-UV purity, and net content. We pulled three real reports and confirmed them genuine: BPC-157 99.04% (lot 20260312), Retatrutide 99.83% (sold under the 'GLP-3 RT' codename), and Melanotan-2 99.55% — all identity-confirmed, all 99%+ — and the brand backs its line with a 99% purity guarantee and refund. Public, named-lab, batch-linked COAs across the catalog are exactly what our 40% COA factor rewards.

What keeps the score at 8 rather than higher is COA depth and reputation, not the lab work or the operation. The COAs are a single representative report per product rather than a per-batch lookup with history (the gap between Woosh and a 9.5 like Glacier), and the panel is the basic three tests — no endotoxin, sterility, or heavy-metals screen. And it's a brand-new vendor (its storefront and COA files date to about April 2026) with thin independent reputation so far — no verifiable Trustpilot, Reddit, or Eroids footprint, and on-site testimonials we can't independently check; it trades as 'Woosh Labs' with no physical address or named owner. Where it's genuinely strong is execution: a polished, professional operation — clean card checkout, tracked and insured US shipping, discreet packaging, a full catalog in stock, fast fulfillment, and aggressively low prices — clearly run by an operator who knows what they're doing.
