Wouldnt worry about getting huge, that aint gona happen, deca is good for some and a good compound to add with test but it aint as strong as test. Deca has to be run longer than 4 weeks, it takes three weeks to kick in.
No need for winny unless your cutting for a comp. I would run this:
TEST E weeks 1-10 400mg/w
DECA weeks 1-8 200mg/w
Follow with a solid PCT as Deca is very suppressive, eat well without getting fat and train hard and you should gain 10-15 pounds which is a good gain.
