Medvinci Research sells research-only singles and blends with prices and size options on the public catalog, including house labels GLP-3 RT and GLP-2 TZ for retatrutide and tirzepatide. The current retrievable /coas/ set contains 18 Freedom Diagnostics documents and 5 Kovera Labs records; PeptideBenchmark confirms all 23 against the exact issuing-laboratory report.
Readers who want an openly priced research catalog with clear house-label mappings and a centralized, independently checked two-laboratory COA index.
GLP-3 RT / GLP-2 TZ are branded storefront labels for retatrutide / tirzepatide. 9 legacy PS* Freedom rows are labeled Previous supplier report and kept as provider-valid history outside current evidence; the 18 current Freedom reports use Medv* codes. Bundles, BAC supplies, and 10-vial kits stay outside the peptide comparison board.
The vendor states Houston, Texas fulfillment area and 346-area support line; no street-level public address verified. Public checkout code WELCOME15 is a vendor promotion, not a PeptideBenchmark affiliate offer.

The current /coas/ index yields 18 Freedom Diagnostics documents and 5 Kovera Labs records. PeptideBenchmark independently confirms the exact search code or report credential at the issuing laboratory and re-checks it on the normal trust cadence. A matched certificate documents the tested sample and does not endorse every vial.

Assayed content is not fill accuracy. Laboratories report net peptide content, and peptides ship as salts, so an honestly filled vial commonly assays below its gross label — a figure under 100% is not evidence of a short vial. These numbers are also not comparable between vendors: they exist only where a laboratory reports net content, so they partly reflect which laboratory a vendor uses.
