This might be a horrible idea and I need opinions on it

I'm a trans guy, and in the state I live in it's nearly impossible to get on testosterone, especially because I'm a minor. I'm really really desperate to get on it though, like I have horrible gender dysphoria and I don't know how I'm going to live life to the fullest if I don't get onto t and get top surgery. I'm thinking about going down to Walgreens and buying one of those alpha male testosterone booster type thingy, but the thing is because it's not a medicated dose I'm not sure if it'll have any severe consequences. I did a little bit of research and all the side effects would be exactly what I want (lighter/ no periods, facial hair growth, thicker body hair, breast reduction, ect.) I did see that some rare side effects was like liver damage and cardiovascular damage or something but I'm honestly willing to take the risk. Is this a stupid idea?
