My opinion for what it is worth. That is way too much gear and more than you would need to see results. More is not always better and there is not quick way to get big. I takes time and work. I think there are pros that don't slam the much stuff. Just save what you have and spread it out a little. I have seen things that said Arnold would use 30 to 50 mg of dbol a week and that was it. Last time I checked he did not look all that bad in his day. Good luck and be safe with your health bro. You dont want to die young!!
Do some research on the stuff my bro. Unless you have an endless supply of cash and a spare organs you get to a point where the risk is not worth the benefit. Your receptors can only except so much shit and the excess will manifest itself in nasty side effects. The point of diminishing returns as you would have it.
My buddy is as big as a fucking house. 6'2" about 260 with 8% BF or so and he has done nothing more than 300 mg of deca for 10 weeks and 30 mg of DBOL for the first 6, with about a 6 week break between cycles. I am not the expert on gh. though, but from what I have read it is not all that effective for the $$ spent. It is more for someone who has reached their potential on roids alone and it helps solidify your gains. I would doubt that you have reached your potential on your third cycle. Save the GH for when you are ready to turn pro would be my advice.
Good luck and I hope that I have helped. Remember you have a lot of life to live in your body and make sure it is a healthy one. You may feel good now but everything has it's price!!!
