I was under the impresion that 25mg/ml of any prohomone/steroid was the ideal concentration in a transdermal formula for the highest percentage of delivery, and any amount above that would just inhibit absorption.

However I see a few of these 'dermabolics' products going as high as 50mg/ml with some of there transdermals. I also see users of T-gel trying to cram in and disolve as much hormone powder as possible.

I wonder, is there some scientific research showing that more hormone is being absorbed with the higher concentration?
