Adipogen-C treatment - Is it safe to inject glucose into the breast for a non-surgical breast enhancement?

I’ve come across a treatment referred to as adipogen-c treatment for non-surgical breast enhancement. It’s supposed to stimulate more fat cells in the targeted area over a course of treatment. Is this safe? I’ve only come across one clinic in London doing this procedure but not sure if it’s more common in other countries & it’s just new in the U.K. I’m not interested in surgical breast augmentation/fat transfer enhancement. This is more for people looking for a little boost nothing extreme.
