What kind of results are reasonable to expect with these pics?

[hopeitworks]

I realized I was thinning for a while but it wasn't until I started getting the comments about a bald spot (thanks everyone ) that I took a picture. Crap, so that's what my scalp looks like.

I'm 25. My whole father's side of the family is bald, but my mothers side is not. Not sure if it matters but I have always suspected I have stupidly high testosterone (type A, athlete, all other physical signs).

I do not feel that my front or temple hairline has really receded at all and I'd actually be okay with no growth here as long as I could prevent it from receding. However I'm starting to get self-conscious about the thinning on my scalp.

I read all the sticky threads and am considering starting the big 3, but in my situation - assuming I can tolerate the drugs - is it reasonable to expect to prevent my hairline from receding in the future while eliminating my bald spot on the top? I realize nobody can tell for sure and I've taken a look through the success story questions, but has anyone started a regimen with similar pics to mine?

Thanks everyone, I appreciate it.
