Is it safe to take steroids before Brazilian butt lift?

Do you mean anabolic or corticosteroids (cortisone)? Either way, be sure and share your usage and reason for taking them with your board certified PS.  You need to balance the risks with the benefits.

Dear Skhunter74,
Every plastic surgeon has his own preoperative protocol which he recommends to his patients. I would suggest you to discuss this with your plastic surgeon.

Corticosteroids affect your immune system and your ability to fight infection. I will not perform a BBL on a patient who is actively taking steroids. If you are put on a dose pack or short term treatment, make sure you share this with your PS. You need to have them all of the way out of your system before surgery.
