COA evidenceCOA quality 9/10✓COA verifiedAll 29 retained reports resolve to exact Kovera records. Twenty-six also matched downloadable official files; Kovera does not expose downloadable PDFs for the other three.
PuraSynth Labs has a functioning US storefront, a complete retained Kovera archive with all 29 reports verified, published contact and fulfillment terms, and working card and alternative checkout.
The evidence supports 9/10. The remaining limits are four unsupported in-stock single-vial strengths, a PuraSynth domain created in March 2026, and no mature independent review aggregate for that domain itself.
01
Complete certificate archive
PeptidePrices reviewed PuraSynth's complete finite archive: 29 Kovera certificate identities across 35 vendor PDF pages, all tied to batch JA2026164. Every report ID resolves to an exact Kovera record with matching product, strength, batch, and results. Twenty single-page vendor PDFs are byte-identical to Kovera's official files, and six newer two-page files contain the official chemistry report plus the separate USP <85> endotoxin report. Kovera does not expose downloadable PDFs for three resolved records, but the exact lab records match the retained PuraSynth files. Every report on file names Pura Synth or support@purasynth.com and includes identity, purity, measured content, and endotoxin results. Twenty-nine exact current product-and-strength rows have Verified COA matches; unsupported strengths and multi-pack totals remain blank.
02
Reputation record
No mature exact-domain customer-review aggregate was found during the September 11, 2026 review. We set the reputation factor at 7.5/10. That judgment remains separate from the laboratory evidence and the absence of an independent review aggregate.
03
Catalog, shipping, and checkout
The live catalog exposed 23 products and 72 dosage or pack options. After excluding recon water and a multi-product beauty kit and consolidating duplicate total package quantities, the comparison import contains 60 rows; 59 were in stock and Cagrilintide 10mg was out of stock. Checkout accepted major cards, Apple Pay, Google Pay, and Zelle. PuraSynth ships to all 50 states, states 0–2-business-day processing, charges $14 for standard 3–5-business-day shipping, and lists two-day shipping at $20 or free over $300. Sealed products are returnable within 30 days, while damaged or incorrect orders require notice within 48 hours.
