COA evidenceCOA quality 4/10✓COA verifiedOne exact Janoshik match for GLP-3R 10 mg; the report prints batch Unknown.
In short: a working EU store and a tested discount, but only one lab report, with its batch printed as Unknown, and a small, low-rated review record.

02
Customer reviews
Trustpilot’s exact-domain profile shows 2.4/5 from eight reviews. Negative accounts concern non-delivery, payment and support; one September reviewer later updated the complaint after receiving a delayed order. The separate ProvenExpert summary has a different source/collection scope and is not merged into this count. Our overall rating stays at 4.5/10.
03
Business and delivery
The legal notice names BergdorfBioscience and publishes Bahnhofsgasse 1, 07407 Rudolstadt, Germany; it says the business is not entered in the commercial register. Its about page claims a 1994 Tübingen founding, but Verisign dates bergdorfbio.com registration to March 23, 2026 and we found no independent record corroborating that founding story. The storefront states worldwide shipping, EU delivery in 5–11 business days, and €9.99 shipping below €250. Checkout showed major cards, Apple Pay, Google Pay and Revolut Pay.
