Direct answer
Ascending Labs has a strong public testing archive. PeptidePrices retained all 40 pages for 33 logical certificates and matched all 33 issuer identities: 23 Freedom Diagnostics and ten ILS Laboratories. Ten of 11 active comparison rows receive exact controls. Tirzepatide 20mg remains blank because the certificate itself says 10mg. Six vendor-copy versus live-issuer field differences remain disclosed.
Ascending Labs scored across our four rubric factors — COA practices (40%), reputation, transparency, and operations (20% each).
Weighted factor result: 8.3/10. The published score follows the weighted result after rounding.

What we reviewed, with the limits of that evidence kept explicit.
Ascending Labs is a US research vendor operated by Ascending Labs LLC. The site publishes a support email and phone number. It advertises same-day fulfillment and fast US shipping. The current catalog has individual peptides, supplies, and bundles. PeptidePrices includes only supported single-compound items and supported standard blends.
The archive is the strongest signal. PeptidePrices inspected all 33 logical certificates and retained all 40 pages. The set contains 16 current and 17 historical records: 23 from Freedom Diagnostics and ten from ILS Laboratories. Every certificate identity matched the official issuer record and names Ascending Labs. Six records preserve field-level differences, including five heavy-metal differences between vendor-published pages and live ILS records. Identity verification does not resolve those field conflicts.
Ten of 11 active comparison rows have an exact current certificate, including BPC-157 5mg and Retatrutide 10mg/20mg. Tirzepatide 20mg remains deliberately empty because both the vendor page and exact Freedom file print GLP-2 10mg. NAD+ 1000mg is unavailable and does not appear as an active offer. Ascending receives 8.5/10. Limited public company disclosure prevents a higher score. Code PEPTIDEPRICES gives 10% off; affiliate status has no score weight.
