Upon its release in 1958, Dr. Ziegler recommended an original dosage of 5–15 mg per day. Another androgenic side effect we see with Dianabol is oily skin, or acne vulgaris. Research also confirms this, with 51.9% of men experiencing muscle loss or muscle tone when taking finasteride (24). DHT is a significantly more powerful androgen than testosterone, with it binding 3-5x more effectively to androgen receptors. DHT is responsible for the development of body hair, prostate, penis size (during puberty), and libido. This happens via the 5-AR (5-alpha-reductase) enzyme, which is responsible for converting testosterone into DHT.
