Medvinci Research Review: Lot-Matched Lab PDFs, Researcher Gate and Final-Sale Terms

Medvinci Research is the store name of Medvinci Research LLC, which lists a mailing address in Sheridan, Wyoming. It sells research peptides as single vials, multi-compound blends and 10-vial kits, and every page presents them as material for laboratory research only, not for human or animal use.

We looked at the homepage, the shop, a product page, the COA directory, the FAQ, the refund policy and the page that holds its shipping and payment terms. The standout is a public report directory tied to lot numbers; the main gap is that test methods are not summarized outside the reports themselves.

Who Medvinci Research is and what it sells

The homepage counts 29 single vials, 5 blends and 30 ten-vial kits, alongside bundles and supplies such as bacteriostatic water. The single-vial range includes BPC-157, KPV, Semax, Selank, GHK-Cu, MOTS-c, Epithalon, NAD+ and several GLP-1 class compounds listed under shorthand names. Single vials ran from about $30 to $120 when we looked, and 10-vial kits cost more, up to about $400.

No founding year or staff names are given. Product pages list strength in milligrams but say little else about the vial contents, and orders ship in a foam-fitted case inside a plain outer box.

Lot-numbered reports from Freedom Diagnostics and Kovera Labs

The COA directory held 40 reports covering 19 compounds when we looked. Freedom Diagnostics issued 35 and Kovera Labs issued 5. Each entry shows a report number, a purity figure, net content, endotoxin status where tested and, in most cases, a lot number in the store's own format, such as MVR-KPV10-003. Reports open as PDFs, and a verify link leads to the issuing lab; Kovera entries add an access code for that check.

The KPV product page carries the same lot, the Kovera certificate number and a purity of about 99.5%, so a buyer can trace a vial to a report without asking support.

There are gaps:

• Three entries list no lot number, and two have no PDF on file.
• Some entries are marked as reports from a previous supplier rather than reports the store commissioned.
• The directory does not name the test methods. It says to read them in each report, so whether a mass spec identity result is included has to be checked report by report.

Labeling and purchase checks

Research-use-only notices appear in the header, the footer and on product pages, and the footer adds that the products are not approved by the FDA for any use. We saw no dosing content, usage guidance or effect claims on the pages reviewed.

On entry, a gate asks visitors to confirm they are 21 or older and acting as a qualified researcher or institutional professional, with an option to leave. The written terms go further, asking buyers to state that they have the training for lawful laboratory work and to accept responsibility for handling and storage.

Ordering, shipping, refunds and support

Payment options include Visa, Mastercard and American Express, the USDT stablecoin and e-debit through Plaid, with wire or ACH available for large orders. Most in-stock orders ship the same business day by USPS, UPS or FedEx, and weekend orders go out on Monday. Shipments are FOB origin, so risk passes to the buyer once the carrier has the parcel. No shipping origin or cold-pack use is stated.

The refund policy, last updated in April 2026, makes all sales final once an order ships. Damaged, defective, tampered or wrong items must be reported within 72 hours of delivery with the order number and photos. Wrong items are corrected at no charge, and approved damage claims lead to a replacement or refund, with a target of 14 business days. Refunds go back to the original payment method, and shipments seized by customs abroad are not refunded.

Support runs by contact form, email and a phone and text line, Monday to Saturday from 7 am to 6 pm Central, with replies usually within one business day.

Verdict: who Medvinci Research suits and what to check

Medvinci Research suits labs that want to match a vial to a named lab's report and that value a written claim window and a published phone line. It is a weaker fit for buyers who need mass spec identity confirmed up front, or who want a return option after shipment.

Before ordering:

• Find your compound in the directory and open the PDF to see which methods were run.
• Match the full lot number on your vial to the report, then use the lab's verify link.
• Ask support which lot your order will ship from, since an older report may not cover it.
