Introduction

Gen-Shi Laboratories Testo-P 500 is presented in a 5-milliliter multidose vial, labeled to contain 100 milligrams of testosterone propionate per milliliter. As part of its harm reduction initiative, AnabolicLab independently procured samples of this product from a European-based internet source to verify its composition and confirm whether it meets its labeled claims.

The samples were purchased between September 21, 2015, and November 7, 2015, and were submitted to SIMEC AG, an internationally recognized analytical laboratory, for HPLC-UV quantitative dosage testing. The analysis, funded entirely by AnabolicLab, revealed significant discrepancies between the product’s label claim and its actual content. This investigation underscores AnabolicLab’s mission to provide consumers with accurate, unbiased data to enhance safety and transparency in the anabolic steroid market. The findings are intended solely for harm reduction purposes.

Testing Results and Authentication

The samples were received by SIMEC AG on November 17, 2015, and the quantitative dosage testing report was finalized on January 5, 2016.
