Joe's advice is 100% accurate.
Before my first cycle, I had a similiar build to you, except you are leaner and looks like you have more mass.
I did Anavar at JUST 25mg ED for 6 weeks and Clen for 2 weeks and I gained about 4-5lbs of muscle and lost some bodyfat. My body also changed to look more like a body builder. My diet also wasn't that great. I was on a calorie deficit and was basically just getting my protein in but with no carbs and fat, so the results would have been much better with a smarter diet plan.
You should be happy with Anavar at 60mg ED for 8 weeks. You WILL see mass gains and your definition will be enhanced. Maybe even some extra fat loss.
