noob needs help

[Matt]

First of all, welcome! - You've come to the right place for advice.

Right then. Deca for 4 weeks!? - Unfortunately that's just enough time for it to shut you down, and pretty much nothing else. You should have run it for a good 10+ weeks along with testosterone to get the benefits. Winny is okay to stack with Deca, but you'll still need the test.

I'm pretty new myself, so I'll let the veterans help you out mate...

Grandmaster how old is this person your giving advice to?
He could be 16, thats why Big asked for age..
