Lack of knowledge

I’m debating getting on Reta as I’ve seemed to have stalled in my weight loss. I’ve worked out for over a year and went from 367 to 330lbs but after a few months I’m stuck. I keep getting stronger in terms of weightlifting but the fat hasn’t gone down. I’ve done some research and I know some information. Was hoping some more knowledgeable and friendly people could answer some questions I have? Things like reconstitution and dosage.
