COA & lab verification
Public per-product COAs: every product page carries a 'View Certificate of Analysis' button linking a batch-specific PDF (full-catalog coverage), all from Freedom Diagnostics — a recognized US third-party lab (reports verifiable by Search Code at FreedomDiagnosticsTesting.com). Reports cover LC-MS identity confirmation + HPLC-UV purity + net-content (labeled-quantity) verification; a standard 3-test panel (no endotoxin, sterility, or heavy-metals screen). Verified genuine from 3 real reports downloaded this session, all identity-'Confirmed' at 99%+: BPC-157 10mg 99.04% (lot 20260312, accession 2604220150, net 11.65mg), Retatrutide 10mg 99.83% (lot 20260109, accession 2604220151, net 11.89mg — sold under the compliance codename 'GLP-3 RT'), and Melanotan-2 10mg 99.55% (lot 20260211, accession 2604220152, net 8.38mg). Backed by a '99% purity guaranteed' claim with refund. The COA factor is genuinely strong (public, named third-party lab, batch-linked, present on the highest-fraud-risk GLP-1/2/3 + BPC compounds) but sits below the top public programs because it's a SINGLE representative COA per product (not a per-batch lookup/history like Glacier's /coas or Evo's library) on a basic 3-test panel. Notes OUTSIDE the COA factor: brand-new (storefront + COA uploads dated ~Apr 2026), 'Woosh Labs' with no physical address or named ownership disclosed, and no externally verifiable Trustpilot/Reddit/Eroids footprint yet (on-site testimonials are not independently verifiable, so not counted as social proof); the affiliate program's paid-comment-shill growth model is a caution on the reputation signal. Operations: card checkout, tracked/insured USPS, US-only (50 states + DC), discreet packaging, full catalog in stock; info@wooshlabs.com, 21+. GLP codename decoded via the COA itself: GLP-3 RT = Retatrutide (slug glp-3). PeptidePrices is an affiliate partner (30% commission via GoAffPro + 'peptideprices' for 10% off) — disclosed per FTC; affiliate status does not influence the rating.
Our verdict on Woosh
Yes on the testing, with a caveat about age. Woosh publishes a public, batch-specific COA on every product page, all from a named third-party lab (Freedom Diagnostics), and we verified three real reports as genuine and 99%+ (BPC-157, Retatrutide, Melanotan-2), backed by a 99% purity guarantee. For a young brand, that's a real verification layer on the compounds people worry about most.
The reason it's an 8 and not higher is COA depth and reputation, not the lab work or the operation: it's a brand-new vendor (~April 2026) with little independent review footprint yet, the COAs are one representative report per product rather than a per-batch library, and the panel is purity/identity/net-content only. Where it shines is execution — a polished, well-run operation with clean card checkout, tracked/insured US shipping, discreet packaging, and a full catalog in stock. A strong COA program for its age, backed by sharp operations — let the reputation catch up and it could climb further.
More about 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.
Woosh — pros & cons
Strengths
- Public per-product COAs across the full catalog — every product page has a 'View Certificate of Analysis' button linking a batch-specific PDF, including on the highest-fraud-risk compounds (the GLP-1/2/3 line + BPC-157)
- Named third-party lab on every report — Freedom Diagnostics (a recognized US lab) — with LC-MS identity confirmation, HPLC-UV purity, net-content verification, and a batch lot number checkable by Search Code at FreedomDiagnosticsTesting.com
- Verified genuine: we downloaded three real reports and confirmed them — BPC-157 99.04%, Retatrutide 99.83%, Melanotan-2 99.55%, all identity-confirmed and 99%+ — backed by a 99% purity guarantee with refund
- Aggressively low pricing (BPC-157 10mg $39.99, Retatrutide 10mg $59.99), full catalog in stock, US tracked/insured shipping with discreet packaging
Watch-outs
- Brand-new (storefront and COA uploads dated ~April 2026) with no externally verifiable reputation yet — no accessible Trustpilot/Reddit/Eroids track record; on-site testimonials aren't independently verifiable, so we don't count them as social proof
- COAs are a single representative report per product (not a per-batch lookup or history like the top public programs), on a basic 3-test panel — no endotoxin, sterility, or heavy-metals screen
- Minimal company transparency — trades as 'Woosh Labs' with no physical address or named ownership disclosed; US-only shipping (50 states + DC)
- Uses a compliance codename on Retatrutide (sold as 'GLP-3 RT') — decoded via the COA itself, but worth confirming with the vendor
