all AAS come with side effects.. they are drugs.
people react differently though. i am in the minority but tren did not give me any insomnia, i slept better on it actually.
i think the reason tren gives insomnia in most guys is cause it can raise bp which has a domino effect on the body and cause additional sides.. headaches, insomnia, feeling blah. for me drols make me feel like that so i know exactly what guys feel on it.
tren gave me raging horniness, de-hydrated body, and suppressed appetite. those were the 3 symptoms that hit me hard. and I also got some bad pumps when i would go heavy.. everyone is different, only way to find out is try it yourself.. if the symptoms become counter productive and hurt your workouts then you should try another AAS.
i had zero symptoms on primo for example so i did not have to worry about my workouts getting affected
