Rowan! I doubt you will read this as you made one post and were sucked into the GS black hole never to return as most do who come here. You are not alone in the black hole! You share it with about 20,000 never to be seen again members.
You say you are underage? According to your profile you are over 18 so you are not underage. Unless you lied about your age you have gone through puberty and once that has happened age does not matter to much as nature has done it's work.
So as I doubt you will read this others can learn from it. I personally have about 20 months prescribed packs of hormones. Would I give or sell them to anyone? No I would not because they were prescribed to me by my doctor. You and others need to understand they are not sweets/candy. The the reason I have so many spare packs is because I have blood tests every 3 months and my dosage changes depending on levels in my blood. Twice my Oestrogen levels have been dangerously high and I mean dangerously , more than 4 times higher than a genetic female. Without those blood tests I would have been unaware of those levels and they would have kept rising and could have caused DVT or stroke or even killed me. Do it the proper way and safest way and see a professional.
