Short temper, agressive, irritable and sometimes moody. Night sweats and some insomnia. Maybe a bit of anxiety.
Now for the good part- strength gains through the roof...hard, dense muscle bellies, a perception if not reality of increased leanness.
Overall, my favorite Anabolic Androgenic Steroids (AAS) of all time...nothing has the impact on a physique like tren does. As long as you know what you're getting into and can deal with it, then tren is unbeatable in my opinion. I feel once you get used to it, positives outweigh the sides.
