Deda gyno is caused by all the prolactin. Your prolactin levels only become a problem when your estrogen levels are out of whack. Just keep your estrogen under control and you will be fine. Don't need to do anything fancy or add any other ancillaries. The only thing you may need to end up doing is slightly changing your regular AI dosage but that's something you will have to figure out.
Are you really going with that 300/600 bullshit you were talking about in the other thread? Bruh please don't do that, you will most likely lose a fair amount of dick function at that level. 750 test/500 deca is what you want JM,,,,at the least,,,with deca your test should always be higher imo
