Honestly guys if I was getting such severe sides from a compound I would stay well away from it.
I've never run cycle doses but felt wonders from 150mg pw Tren A. No unwanted sides other than HDL down to 30.
It boosted mood, confidence, libido, even reduced anxiety, better sleep, made me aggressive but in a balanced way.
That, as long as I have enough estrogen circulating, or hell breaks loose.
Right now I'm running 200mg (100mg 2x w) Tren E and I'm not feeling much from it.
As of lethargy, Tren makes me feel rather hyperthyroid in the start, but this evens out in day. My opinion is that it affects thyroid binding proteins so that an high is reached initially followed by slight hypothyroidism.
Mindlessness? Tren is a progestin. Endogenous P4 (progesterone) has anti-cholinergic activity. That means it antagonizes acetylcholine to some extent in the nervous system. ACh is your friendly neurotransmitter associated with reason, logic, and memory. When such antagonism is present, the system will try to balance it by compensation mechanisms. But, if dosage of the compound if too high, the system might fail in the attempt.
Sides are most of the time dose dependent, if you feel overrun by Tren, you are either pinning too much or you should avoid it.
