There is a 13 y.o. f2m in my support group. I believe he has been on puberty blockers. I'm not sure what age he can start T, but he turns 14 soon and will be starting then. I don't whether his age, or the time in therapy/on blockers is the determining factor. I'm not sure how old you are, but the puberty blockers only can be started before the onset of puberty.
This is what his ally (his aunt) talked about in group. I don't claim to know the facts, just passing on what I've heard.
