im a big fan of mestanolone but i’ve never ran it by itself, my brother who plays soccer (6′ 175lbs pretty shredded) has the same goals as you. he’s getting ready to start a mestanolone only cycle 100mg/ed for 6wks, as soon as i’m confident he will follow his diet and training schedule 100% i’ll have him start it. im very interested on how it will affect his strength, speed, muscular endurance, and mental state. on paper it sounds ideal for what your goals are but i’ll let you know how it works out with my brother.
