The increases in weight, appetite, and hemoglobin and serum albumin levels, all highly desirable feature that go along with increased vigor, strength and sense of well-being, were side effects which opened up a promising new area of application.

These labors resulted in several new compounds that have met with varying success in their clinical application.12 Androgenicity, salt retention and occasional jaundice due to cholangitis, still limit the clinical usefulness of some of these products.The new anabolic steroid, stanozolol t ( Fig.
