Caber is not going to help with aggression or insomnia. Lot of people resort to anti-anxiety meds with Tren, like Xanex or Ativan. R/X sleep meds work for the insomnia. Not suggesting you take any of the above, but I know many who utilize these drugs when using Tren, especially at high doses. Understand going in that the potential for abuse and addiction when taking these drugs can be very high.
