i think its through androgenic steroids mainly
just becuase their function increases aggression and male characteristics
IMO, and im sure alot of people will agree with this, the feeling that steroids give u, (ill call it invincibility) will effect ur sleep
i mean i rock up to the gym atm, and i just wanna rip the dumbell in half lol
anyways its seems the trend anyways, high androgenic steroids like trenbelone have been shwon to cause sleeping issues
ur using test, which is also fairly androgenic
also i think the huge sex drive from test effects ur sleep, i mean i personally cant get to sleep atm without rooting my gf twice, and then having 2 pulls after that (use to be 4 roots but misses wasnt getting enough sleep so shes limited me to 2 on weekdays
weekends i get 4

, sleep great aswell
