Will the scanner read me correctly if I use anabolic steroids?

Steroid based medications, will influence the results due to the role of those substances in the body

BIA provides an analysis of the human body at the time the scan is performed, reflecting the body composition of the individual at that time.  As with any form of body composition analysis, including all forms of BIA, Bod Pod and DEXA, medications, including steroid based medications, will influence the results due to the role of those substances in the body, particularly with respect to intracellular and extracellular water and nitrogen retention within lean muscle tissue.  As previously mentioned, steroid medications and other medications that alter hydration status such as creatine, beta 3 agonists, peptides etc. will influence the result where it relates to Lean Body Mass, in particular, Total Body Water.

It is important to always scan under the same conditions each time with the same variables to ensure consistency and repeatability of results.
