Summary

Dragon Pharma Masteron 100 is presented in a 10-milliliter re-usable vial, labeled to contain 100 milligrams of drostanolone propionate per milliliter. To ensure transparency and accuracy in product claims, AnabolicLab procured samples of this product from a European-based internet source between October 7, 2015, and November 7, 2015.
