i heard that you can increase your size by taking finasteride which also goes by the name propecia, this is used by people who are losing their hair, the theory is that dht makes your penis grow during puberty, but after puberty the dht receptors arent as sensitive as when you were going through puberty wich is the reason your penis stops growing att he end of puberty, by taking finasteride for 3 weeks or a month you prevent testosterone from converting into dht which means no dht will be flowing through your body which will make the dht receptors in the penis sensitive again as if one was going through puberty again,this guy said he took finasteride for a month and then stopped cold turkey and his penis started growing rapidly over a course of 6 weeks, he wouldnt hwo much but he said it grew alot. I'm pretty sure no one on here has done this so naturally you would be skeptical but I am going to try this one day and see how it goes.
