If I stop using Wigobi midway, will the effectiveness drop significantly?

I am currently considering getting Wigobi for my diet. Wigobi involves gradually increasing the dosage every four weeks until the 16th week, right?

However, if I stop midway without continuing until week 16, will the effectiveness drop significantly?

I have a feeling that going until week 16 would lead to more stable weight loss, but I’m asking because I’m wondering if it would be okay to stop if I get satisfactory results in week 8 or 12.
