changing tren brands

switched from mos to lambo tren ace on week 6, its been 1 week,
so far my appetite just came back put on 4 kg from binging in 1 week, sleeping better, feeling better, more aggressive, no injection pain, not dreaming much.
With the mos tren i had anxiety, waking up earlier than i want to, tired, dreaming, unbearable shoulder pip that affected training and mood for weeks, not in glutes though.

I got even bigger pumps after putting on the 4kg in 1 week and veins are still there. Is it possible that changing brands has taken away some of the tren side effects (mostly bad ones, except lower appetite) or the tren is dud?
