Are offbrand Kybella injections safe?

A well-loved local medspa offers a deoxycholic acid injectable, called Fatbella, used on various parts of the body and for half of what Kybella would cost. You can't find any info about Fatbella, other than a small paragraph on the medspa's site describing what it does. However, they openly talk about it on social media. Reviews of both the business and Fatbella are great. I feel comfortable with the medspa itself. I just don't find much about places using their own brand of fat dissolvers.
