Heres may take. Bro science " you never need an AI on cycle… Taking an AI stops gainzzzzz" just like most bro science there is some truth to it.
The first part you never need an AI. Thats part truth. I dont think people need an AI on cycle nearly as much as they think they do. Problem is these first cycle plans all over the internet have an AI built in which leads the reader to assume its neccessary. I think you should have one on hand and take only if necessary. Im running 750mg test /week and i took an AI for a few weeks mid cycle then stopped. Id take it when i started feeling emotional but then realized that id rather feel a bit emotional then how i feel when i take added drugs.
The last part “it stops gainzzz” this is just pure bullshit. I forget how the bros explain this but its dumb. Ya maybe if you tank your estrogen it will hinder gains but thats it.
I have a love hate relationship with bro science. Bottom line is most of the time there is truth to it even if it sounds stupid. You just need to be able to filter out what that is. Try to listen to smart bros, bros with results to back up their bro science claims.
