Nobody wants gyneomastia and I'd like to play it safe as possible...

This will be my first cycle ever. I was planning on a cycle of enanthate. Probably about 350mg first injection, then 250mg for the rest until my last which I'll reduce to 150mg to get off easier. After this, I was planning nolvedex, or clomid 2 weeks after my last injection for 2 weeks.

My question is, can gyneomastia occur after a cycle like this? Generally, what is the cause and what other precautions can I take? I want to start slow in case my body doesn't react well. If gyneomastia can occur after one cycle I'm not sure.if it's worth it.

I appreciate the help in advance.
