I have recently been looking into butt enhancements but since I am on the slimmer side I don't want to do a bbl but I also don't want to spend $15k on filler that won't last. I have found a clinic in the UK that offers progesterone injections for permanent results. I know progesterone is a hormone and it is injected into butt when it comes to pregnancy so it sounds safe. I just want to make sure this is the right thing for me ? It is a big thing in the United Kingdom. Has anyone tried ?
