The ratio is fine. Everyone always say to keep the ratio no higher then 1 to 1 and not let the deca go higher then the test. But.....everyone is different. I have ran deca 100mg higher then my test before with no sides what so ever.
i would just never go above 400 w/deca--b/c it is the law of diminishing returns and increased sides....but that is just me, everyone is different. you will find what is best for you--but it is trial and error. when mr wee wee will not get harder than a cotten ball--well, you went too high.
