My Man i would do some research before you delve into all of this. Not trying to be a dick just trying to help but you have started i believe 3 threads about different anabolic topics in a very short time frame.Guys on here are knowledgeable just check some threads and chime in here and there and you'll find all the info you need. With that being said back in the day guys used to run primobolan/nandrolone and maybe a little dianabol here and there without any testosterone so that can be done for sure. But we need estrogenic conversion and dht conversion for keeping an optimal mood,libido,outlook ect.
