Yes it is ok. If you are new to gear, 350mg should do alot, but you can go to 500mg mid cycle. Just remember that it takes a few wks for test cyp to kick in, so what you are seeing at wk 3-4 isn't nearly as much benefit as what the same dose will feel like at wk 6-8. Also, if you up the dose, you may need more AI. The more you take, the more chance there is that you will see estrogen side effects. For your first few cycles, I would not go above 500mg EW
