When I took them I didn’t notice any significant weight gain or loss. I had a friend who gained 30 lbs, but she was about 100lbs to start, always been one of those bone skinny girls when she was younger. Other friends, maybe 10 lbs or so, but like I said if anything I might have gained 5 lbs. I think its because the hormones affect your appetite, making you hungrier more often, but as long as you pay attention to that and keep doing what you’re doing you’ll be fine.
