Homebrew Tren Quality Control?

Half way through an 8 weeker sust/tren/d-bol and just switched (4days) to a second batch of homemade tren.
Suddenly i am getting irritable and sweating profusely for no apparent reason. I also seem to have more energy. Is this normal effects of tren? Taking 75mg/ed but i was wondering if the second batch could be alot stronger. Can homebrew tren really vary that much in strength?

The answer is yes and tren effects everyone differently.
