Geez, take a breath between your sentences, seriously. And maybe you should do some research on yourself. Did you try
TSRoadMap.com? It's an amazing starting point. There are a lot of questions you won't need to ask if you read that website. It's interesting.
Grammar naziing and annoying advice aside, here is a very short description.
Blockers: Those block the hormones your hypophysis produces. These hormones, named FSH and LH, are the chemical signals that tell your body, notably your testicles, that it's time for puberty. It's reacting to these hormones that your testicles make testosterone, which masculinizes your body.
Essentially, these hormones will halt, for now, puberty. You will stop changing and might go back a little. If you'd started them at, say, 10, you'd have stayed a "child" until you stop taking them. Note the quotes though: blockers do not block growth; it stops the "male bonuses" that come with it: broader bones, shoulders, more muscle, destructed voice, beard, etc. So you'd be a hm. Tall "child", more like an androgynous being.
The goal for blockers is to put your body on "pause" until therapists and doctors have made sure transition is right for you, and law/culture allows you to go forward (18 most of the time). After blockers, if they're taken soon enough, if you start HRT, you pretty much develop following a complete female pattern, without the scars from male puberty.
Hormones (estrogen, actually) are what will, instead of just stopping the changes, start female changes: breasts, etc. If you've not had a male puberty, or not all of it like in your case (if started early or blockers have been taken), they are 100-300% more effective (those numbers are NOT scientific, just my opinion). But in all cases, male puberty or not, they instigate a female puberty, minus the periods. Soft tissue changes, whilst bone only changes if there has not been a full male puberty. It may change a little if it's recent.
But hormones, unlike blockers, have permanent effects, so you can't get them as young as you want.
If you're on blockers, you can "almost" have a normal female adolescence (you won't have breasts real curves, but well, for some girls, it happens much later). And as soon as the doctors authorize you to, you can blossom into a woman, to so say. And if for some reason you can't or don't want to transition, it's possible to just stop blockers, and male puberty will start "as planned" by the body.
Does that help you?
