There both great.
Personally I love superdrol.. 20mg up to 6week. 30mg is normally recommend no more than 4 weeks. Make sure to take some type of cycle support. Drink plenty of water.
You may experience some crazy back pumps, or if your someone who loves cardio or just does a lot of cardio. Your calf's will feel like there gonna rip through your skin..
Also superdrol can make you feel sluggish. Keep an eye on your bp. You may have to dial in your carbs. Superdrol is known as a carb monster also.
Changes on superdrol can happen rather quickly. Strength will go up very fast.. take caution not to injure yourself. Often times your tendons and ligaments may take a hit because they can't keep pace.. so move with caution. I'm not trying to scare you but want you to be properly informed.. your body will seem to transform in those 4-6 weeks. You will definitely look and feel like a boss..
Also a pct is definitely recommended!
Good luck and keep us updated on what you decide.
