Aprox 2 weeks ago i weighed about 215 lbs. I have been on SD for 1 week. I weighed in at 223 Lbs today which is a all time record for me. I never been able to put on mass so quickly in all my days of lifting. Theres no question if this stuff is working or not. Im still wondering how much more i can gain. Its honestly been about .5lbs a day. I think i prlly weighed about 217 when i started the SD. 5lbs in one week is huge!. My goal for the summer is to weigh 230 and put up 300lbs on the bench. As far as strength gains I am deff seeing some, but not anything as drastic as the mass ive gained. I must keep in mind that ive only completed 1 week.Also does SD have any affect on hair loss?lol Overall im very impressed with this product....so far
