I have been taking this sup since it basically came out... so a long time. I have taken an extended break several times so I have that experience also.
Yes, I feel an increased aggression feeling when using it. I chalked this up to it working like it is supposed to. I never used any true steroids so I can't compare it there. To me, it almost fights depression and lack of motivation.
No issues with hangovers being worse, etc. I just feel so much better when taking it that I certainly notice less anxiety and depressive moods when taking it. I use the 5 days on and two days off cycling and tend to take it during the week and skip weekends.
Best sup ever for this 51 yr old.
