How much does it usually cost to get weight loss injections?

I have a body type that makes it difficult to lose weight. It really just isn't coming off. I think I need to get weight loss injections with the help of Maypure. I want to set a rough budget before I go for a consultation soon. How much should I expect to pay for a prescription for these injections? I'm also curious if there is a significant price difference between paying for a weekly package and getting them done individually. I suppose getting them once would cost more, right? Of course, it varies depending on the dosage, but sharing the approximate average cost would be a huge help in making a decision. Since it's my first time, I have absolutely no idea.
