    After being burned so many times by other labs on their masteron, I was hesitant to buy yet another masteron product. Considering the many other reviews I’ve heard from flash’s version, I decided to give it one last shot at finding a decent masteron . Sure am glad I did. I have no doubts this is the real deal. Masteron is my favorite aas and I am glad flash is here to supply it.

    So many fakes out there… I knowhow Mast affects me… This is by far the best Masteron I’ve run in a loooong time… Won’t use anything else… Smooth as silk to pin too!!

    Every time I start using Flash’s Mast Prop within a week I can noticeably start to see my veins pop out with that added hardening of the muscles, excellent Product.

    I’m using this to keep some e2 down while running some extra compounds from Flash. It’s doing it’s thing and helps to make me just feel good. Great compound and excellent service Flash thanks.

    I’ve been using FLASH LABS Masteron Prop for several months because I was getting half hard erections. Now my wiener is hard as steel. I recently added proviron and the two compounds together make my dick like it was in high school, always ready to go. The masteron brings out crazy vascularity and pulls subcutaneous water out giving me a great contest ready look. I love this stuff!!!
