They will definitely limit your growth.
That's completely false. I store my contact lenses in test cyp. That way when I put them in right before I go to the gym each day I get a quick testosterone boost due to the good absorption of the eye membranes. I use test cyp due to the shorter half life. My buddy was using prop and his dosage was too high. The "spot injection" really threw of his symmetry.
I know some of you guys are gonna claim BS so attached is a pic of my training partner after high dosing using the contact method.
