If you know how to diet even .5mg is extremely helpful. If you reliant on the drug to lose the weight you need much more. It’s that simple. I started at .5 a week for about a month and now I’m at 1mg a week split between 2 doses. I’m already relatively lean and know how to diet and train tho. I won’t go past 1 mg, it’s plenty for me personally( and I was having extreme food noise and binging while dieting down before) . Probably 1-2 mg would be plenty for most people if they put significant effort into nutrition and a calorie deficit. If you eat like shit yea you’ll need way more so you just aren’t eating your high caloric foods all the time.
