Medvinci Research Review: Pricing, COAs, Testing, and What We Found
An independent Medvinci Research review covering Houston-area fulfillment claims, openly priced research vials, GLP-3 RT / GLP-2 TZ house labels, and 13 exact Freedom Diagnostics / Kovera Labs records on the public /coas/ index.
Medvinci Research is now a curated vendor on PeptideBenchmark. That decision rests on what a reader can check without guessing — public prices, milligram strengths, house-label mappings, and exact Freedom Diagnostics / Kovera Labs records linked from a centralized COA index.
Reviewed August 9, 2026; testing evidence re-audited August 20, 2026. PeptideBenchmark has no affiliate, coupon, sponsorship, or paid-placement relationship with Medvinci Research. The vendor sells research-use-only products; this is a commercial-transparency and documentary-evidence review, not human-use guidance or medical advice.
The short version
We found a research storefront with:
- openly priced single-vial offers and Size variations on the public catalog;
- house labels GLP-3 RT and GLP-2 TZ for retatrutide and tirzepatide;
- Houston-area fulfillment language and a 346-area support line (no street-level address verified);
- a public /coas/ index with nine exact Freedom Diagnostics reports and four exact Kovera Labs records.
The catalog is usable for $/mg comparison without an account. Certificates are centralized on /coas/ rather than scattered JPEG galleries on each product page. PeptideBenchmark confirms exact Freedom Diagnostics and Kovera Labs report credentials independently; a matched report documents the tested sample and does not endorse every vial.
What we found in the catalog
Medvinci Research lists live prices on its public catalog. PeptideBenchmark promotes every clean mg-normalized vial so Pricing and Stack Builder stay honest.
| Catalog result | Count | PB treatment |
|---|---|---|
| Public parent / variation offers audited | 24 | Kept in the catalog check |
| Comparable in-stock vial rows | 14 | Published to Pricing and Stack Builder |
| Out of stock | 0 | — |
| Deferred | 0 | — |
| Out of scope | 10 | Bundles, BAC supplies, 10-vial kits, Lipo-C |
House labels matter here:
- GLP-3 RT → retatrutide
- GLP-2 TZ → tirzepatide
Current offers can be compared on PeptideBenchmark Pricing, and mixed-product requirements can be modeled in the Stack Builder.
Testing transparency
Browse preserved records in the Medvinci Research COA results.
The current retrievable /coas/ set contains nine Freedom Diagnostics documents and four Kovera Labs records. PeptideBenchmark confirms every exact Freedom search code or Kovera report credential against the issuing laboratory. Eleven legacy PS* Freedom cards now say Index only and are excluded from the current-origin count; the nine current Freedom reports use Medv* codes.
A matched laboratory report documents purity, identity, and net content for the tested sample; ten of the current reports also expose endotoxin results. It is not a sterility guarantee for every vial that later ships under the same label.
Location and fulfillment claims
Public contact blocks reference Houston, Texas fulfillment and a 346-area support line. PeptideBenchmark maps the vendor-stated city-level location on the peptide map and does not treat marketing purity language as laboratory-confirmed unless an exact issuing-laboratory report supports a number.
The checkout code WELCOME15 is a vendor promotion. It is not a PeptideBenchmark affiliate or sponsored discount.
What this review does not claim
- No binary “safe / unsafe” or “legitimate / illegitimate” verdict
- No endorsement of human use

Common questions
Is Medvinci Research legitimate?
PeptideBenchmark does not issue binary legitimacy or product-safety endorsements. We confirmed an openly priced research catalog, Houston-area contact language, and 13 current public records—nine Freedom Diagnostics documents and four Kovera Labs records—against the exact issuing-laboratory report. Those facts create an inspectable commercial and documentary record; they do not establish the condition or safety of a physical vial.
Does Medvinci Research publish COAs?
Yes. The current retrievable /coas/ set contains nine Freedom Diagnostics documents and four Kovera Labs records. PeptideBenchmark confirms each exact search code or report credential at the issuing laboratory. Eleven older Freedom rows are index-only and are not counted as current certificate origins.
What do GLP-3 RT and GLP-2 TZ mean?
They are Medvinci Research storefront labels. PeptideBenchmark maps GLP-3 RT to retatrutide and GLP-2 TZ to tirzepatide for cross-vendor comparison.
Where is Medvinci Research based?
Public contact blocks reference Houston, Texas fulfillment and a 346-area support line without publishing a street-level address PeptideBenchmark could verify.
Does PeptideBenchmark have an affiliate relationship with Medvinci Research?
No. At the time of this review, PeptideBenchmark had no affiliate, coupon, sponsorship, or paid-placement relationship with Medvinci Research. The public WELCOME15 code is a vendor promotion, not a PeptideBenchmark affiliate offer.
