1) Nope, not yet. I'm only 11 weeks in though, so it might happen later on.
2) It started dropping after the first 5 days, and it's still dropping.
3) I gained A TON of weight. Some of it is muscle, but mainly fat. So far i've gained 20 pounds. It really sucks, i've never had an issue with my weight before. I noticed a 10 pound weight gain about a month in. So i started eating REALLY healthy, and cutting out all deserts. Unfortunately, haha that hasn't helped at all. I gained another 10 pounds. It's totally testosterone related. I think i'm going through the awkward chubby stage that happens to a lot of boys when they first hit puberty.
