To begin, your diet is way off. Your BF% is extremely high for someone wanting to use AAS.
Deca only cycles are a BAD idea.
If you want to get big, you have to adjust your diet accordingly. Instead of 3000 calories a day, up your caloric intake to about 5000-7000 calories a day. Your protein intake should be about 1.5gr - 2gr per body pound. So, your protein intake should be doubled.
Tren enan is good stuff, granted you are familiar with tren and know how much your body can handle. Taking it at 75mg a week will go unnoticed for sure. It's hard to tell how much your body can take, and that's why tren enan should be used by those who have used ace at least once before. Tren enan is best suited for experienced users of tren ace.
Since you have what you have, I would probably drop the tren and do a test only cycle. I would still try to get your BF% to the low to mid teens before you start. I would suggest a dose around 400-500mg e/w.
Since you have prop, you can take it ED or EOD (you have to with prop). And I would save the tren for another time. I think you will be wasting your money if you use tren now, and risking the sides. Your BF% is too high for tren to work it's magic.
If you run a test only cycle, all you will need is some clomid for PCT. You can take HCG during your cycle to prevent testicular atrophy, or you can take large doses at the end during PCT. I prefer the first method. This way, you can save both the nolva and tren for another run. This is my advice to you given the stats you quoted. I'm sure others might have a different suggestion for you. Good luck!
