The higher androgenic index a steroid has, the more effective is for beta oxidation-lipolysis of the subcutaneous tissue, leading to muscle hardness.
On the other hand, there is a higher reduction rate to dihydrotestosterone, leading to andogenic side effects such as benign prostatic hyperplasia, male pattern baldness-androgenic alopecia, acne, oily skin, body/facial hair growth, aggressive behavior, as well as erythrocytosis.
Anabolic steroids having a lower androgenic index than testosterone have the ability to cause a positive nitrogen balance-tissue anabolism and act against catabolism.
Furthermore, the androgenic side effects (acne, hirsutism, neuropsychiatric disorders, prostate enlargement, male-pattern baldness, suppression of the hypothalamic pituitary testicular axis, neuropsychiatric disorders) will be less, but always are dose and time dependent.
