I’m getting my BBL done in a week. Is it okay to take Apetamin to gain as much weight as I can?

Congratulations on your upcoming BBL, MAL95!I personally would not recommend taking the weight-gain supplement before your surgery for a variety of reasons.  First, while gaining weight has the potential benefit of increasing the available fat for transfer during a BBL and the potential for enhanced buttock/hip results, you are not guaranteed that the weight gain will go to areas that are useful and usable.  Additionally, after surgery, if you try to lose weight to improve any facial fullness, overall thickening of the skin due to the increased fat of the subcutaneous tissues throughout your whole body, or any abdominal fullness due to internal fatty deposits, the fat transferred in the BBL will shrink as well.More concerning is the potential effect of certain supplements on bleeding or one's chemical response to anesthesia.  Even though a supplement may be "natural," it does not mean that it doesn't have multiple, sometime unintended effects on the body and the body chemistry.I would definitely defer to your surgeon and his/her experience and preference.  I also would strongly recommend that you inform your surgeon of any and all supplements that you have taken over the last couple of months, and certainly in the week(s) prior to your surgery.Good luck with your surgery, and I hope you achieve the results you were hoping for and have a speedy, uneventful recovery!  Dr. Ghafoori 

This is best to ask your PS since your surgery is so close. My advice is if you gain weight before surgery make sure you keep it on forever after the surgery to keep the results otherwise it will just shrink away.
