IFBB professional bodybuilders are literally walking experimental drug laboratories. As with all experimental protocols, time is required to determine the results.

Every drug has side effects, and as a weathered and very wise, old West Texas physician once told me, "Boy, there’s no free lunch in pharmacology."
