Test + deca is pretty much the gold standard for increasing size and strength. It's a classic 'bulking cycle'. Your test dosage is really low. I like a dosage of 500mg/week for testosterone + 300mg/week for deca. Running the testosterone higher then the deca will prevent libido side effects.
The main problem is that both deca and test are known to cause a lot of water retention if you aren't using the proper support supplements with your cycle.
Remember to include the proper support supplements with your cycle:
1. An AI to keep estrogen in the low-normal range. Aromasin at 10mg EOD or liquidex AI from n2bm.com works.
2. An anti-prolactin drug to keep prolactin in the low-normal range. Cabergoline at 0.25mg EOD is a good dosage.
The support supplements are very important because high estrogen and prolactin levels can lead to side effects like gyno and water retention.
Here is how I would run your cycle:
Weeks 1 - 14 <- It's best to do long and mild cycles with deca because it has such a long ester
testosterone e/cyp 500mg/week
deca 300mg/week
aromasin 12.5mg every other day OR liquidex AI from n2b.com (follow the directions on the bottle)
cabergoline 0.25mg every other day
After your cycle run the perfect PCT protocol:

^You need a much better PCT then just nolvadex. That is no where near sufficient for a PCT. Your natural testosterone production won't recover and you won't keep all the gains you made on your steroid cycle. Run the perfect PCT protocol after your cycle and you have nothing to worry about.
