I applaud you whole-heartedly, but I honestly doubt that's 20lbs of muscle, that would be some Fat and Water too. You'd never get that much lean mass that fast. Heck even female pros on Steroids can't get that much that fast, I don't even think a pro could, though possibly at a pinch, and that's on a very advanced cycle lasting 5 maybe 6 months.
I don't know the length of the longest cycles, but they are about that. most new or new-ish users, wouldn't go for that long I don't think.
As I say though, I too applaud the efforts, and think a female of 14, looking to do what you're doing, should be admired and respected.
Just remember though that at some point, you might become a person with some noticable mass, who is given some negative comments, as some people don't like the female with meaty size, not fatty size.
Predjudice, ignorance, fear, call it what you will, but you WILL have to be a bit thick skinned, incase you sometime in the next 1-2 years, start to get the occasional bad comment
As I say, I really wish you so much luck with your goals, and whilst I don't think your goals are a must for all females, it's healthy, it's perfectly acceptable, and it should be supported and encouraged.
For a female of 14 looking to do what you're doing, it's not common, but it's not wrong, so don't ever let anyone make you think you're doing something wrong, because you'll be the one who's feeling better for it, in 60 years.
Keep going, GOOD LUCK, and chin up okay
