Dbol can be felt. Out of any compound it's known also for it's euphoric/mood boost aspect. I'm sure it's to do with a dopamine/gaba increase? Don't quote me though. Moreplatesmoredates did do a video on it.
Alot of people report the mood effect from dbol specifically.
I personally don't like the compound. The back pumps/pain are horrendous. I would wake in the morning feeling like I had done 40 deadlift sets the day before. Destroyed my lower back.
In terms of results. It just whacks a huge amount of water onto you. It does build some mass but it's mostly just water. Which in a strength aspect is perfect.
For the OP. I doubt it's fake dbol as it's such a cheap compound. Give it more time and see how it goes
