In the end, if u were lucky enough to keep 10-15 lbs, realistically it wouldnt b 10-15 lbs of "literal muscle". Heres my personal experiences....Im 48 yrs old, did my first cycle @ 40 yrs old. For 7 1/2 yrs, I did 2 cycles a year, always taking the recommended time off between cycles. I ALWAYS lost most all of my gains every damn time. Ive read all the post...."I did a cycle & kept 90% of my gains", or 80%, or 70% & so on. Personally I dont believe any of that. Ive never done it nor seen any of the many guys I know that juice do it either. Ill believe it when I see it. Ive experimented with diff pct & it got a tad better. My belief & experiences are if you think you're gonna do a cycle & keep most all your gains, you will be very dissapointed "in my opinion." I hope you hav better results. I took 2 1/2 months off from my last run, lost most of my gains & went bac to the spot I always seemed to go bac to & for me that is 264-268 lbs with the same loss of strength. Had a physical, test levels were 400ng. I went bac on Jan 1st & have been on since & hav no plans on coming off again. Im 6'3", currently 287 lbs & max 420 on bench. At 280 u could still see a little ab seperation on me. My points are...I feel my training is good due to where Ive gotten myself. My diet, I eat all I can for calories, some of its not healthy food, a lot is. Im not on a specific diet. I got tired of the roller coaster of cycling, gettin big, loosing it, gettin big, loosing it. RickRock13 said this...."Now once you go beyond your genetic potential, things change. You need to stay on gear to stay at that level, but that's a whole different story and the majority or people never see that level." I feel like this describes my situation. This is a heck of a game to figure out wat works best for each of us. I know some will disagree with my beliefs & thats cool bro's, just throwin my thoughts out there. If you can run a cycle & keep a lot of your gains then you're doing great. I couldnt & got tired of the ups & downs. I hope everyone has awesome cycles, grows a lot & best wishes & good health to us all! "Living Well Is The Best Revenge"
