From my experience Masterone has its place and thats in prep. Ive used a few times when just cycling and I didnt see anything different except hair loss. I probably cycled 6 times before trying Mast, high dosage cycles no less and never had any hair issues. My hair shed when I used mast at low dosages, but this time in prep I used a higher dosage, my hair hasnt stopped falling out and I lost a ton, not a little. I feel the risk versus reward isnt there unless used in prep. Used in a regular cycle you most likely wont even be able to tell if its doing anything. You could just run your tren a little higher or add some deca to it and get much more from your cycle.
