I love deca, but i have always used small doses, and never felt the need to go higher. I guess I am lucky with it, at 300 a week i continue steady, happy gains with no noticable sides. No puffy nips, no hair loss, no bloat really, no acne, etc etc.
I have been cycling for 6 years now, and more and more I am happier using low doses of just about everything.
