I've been researching winstrol and asked a buddy of mine who is a sprinter if he took it and how his results from it were. (I knew he has taken it in the past) To my surprise he said he was no longer using it but using a steroid I have never heard of by the name of mestanolone. Looking it up online, it was said to be used by the Germans back in the day and helped with strength but didn't help with putting on weight. My friend explained that a lot of sprinters he knows have transferred over to using mestanolone instead of winny due to the lower chances of sides and joint pain. Does anyone know anymore information on mestanolone? If it really is better than using winny? And what the differences between the two are?
