The UGL known as Golden Lab Steroids first hit the european market december 2019.  The line up of products looked good, the labelling very professional, and did show some janoshik lab results too, although to be fair, the lab results were performed by the UGL itself, so take from that what you will.   You can find golden labs at https://goldenlabs.org/en/

A customer decided to send Golden Labs Masteron Enanthate off for testing, which the label claim shows to be 200mg per ml.   Not only was the dosage lower but the compound was different. The Masteron Enanthatate made by Golden Labs contains 152mg of Masteron Propionate only.
