Summary
Alpha Pharma Healthcare’s Mastebolin is presented in 1-milliliter ampules, labeled to contain 100 milligrams of drostanolone propionate per milliliter. To validate these claims, AnabolicLab procured samples from a European-based internet source between October 7, 2015, and November 7, 2015, and submitted them to ChemTox SAS, an independent analytical laboratory specializing in anabolic steroid analysis.
Testing included GC-MS/MS quantitative dosage testing to confirm the product’s composition and potency. The analysis revealed a measured concentration of 83 mg/ml drostanolone propionate, indicating an accuracy of 83% of the label claim. This falls significantly below the declared dosage, highlighting potential issues with manufacturing consistency.
The product’s authenticity was verified using its serial number (IRU21L7C5G) and authentication code (V4T924iUi) on check-alpha.com.
Testing Results and Authentication
The samples were received by ChemTox SAS on November 19, 2015, and the analysis was completed on December 17, 2015. The product was identified with a batch number of MB1403.
