I recently purchased some Liquid Clenbuterol.

I started working out in January. I'm working with a trainer and am doing 20 minutes of medium impact cardio followed by weight lifting with free-weights.

I'm 6'2" tall
I currently weigh 420lbs.
I have no heart problems or any other health problems.
My cholesterol is borderline high
My blood pressure is just a hair UNDER what the doctor would call "high"

My current goal for working out is weight loss. I'd like to get down to a weight of approximately 300-325. I like being a big guy. Since I have started working out 3-4 times per week, I have lost about 30-40 pounds and have replaced quite a bit of "flab" with muscle. I have a LOT more to go...

Based on this information, what dosage for Liquid Clenbuterol would someone recommend for me? This is my first time ever taking it.
