Switching brands. 250mg/10ml question

[Loser123]

I have a quick question just an example..

Say you're on trt using like 120mg twice a week..
A 250mg/10ml bottle..

Then you switch to some other dudes brand..

If you start getting oily or acne or fatigue

That's a sign that it's over dosed or underdosed?

Also would upping an extra 30mg a week be noticeable if it was actually a 300mg/10ml?
Not gonna say the whole issue but apparently the label was mislabeled
