Tren is a wierd drug for me too! Some days I feel great and others I feel like sh*t. Moods are definatly all over the place, especially at higher doses. I've found if you adjust your dose it is possible to find a happy medium between too many sides and not working. That dose for me is about 86 mg ED.
Just try to remember when you feel like ripping someone's face off, it's just the tren telling you its working.
