A steroid hormone related to the hormone testosterone. It increases protein synthesis within cells, which results in the buildup of cellular tissue (anabolism), especially in muscles. It also has androgenic and virilizing properties.

| 1-testosterone | An anabolic steroid that differs from testosterone by having a 1,2-double bond instead of a 4,5-double bond in its A ring. A potent androgen with anabolic properties, it was legally sold as a prohormone in the U.S.A. until 2005, when it was reclassified as a Schedule III drug. | Delta(1)-dihydrotestosterone |
| boldenone | An 3-oxo-Delta(1),Delta(4)-steroid substituted by an oxo group at position 3 and a beta-hydroxy group at position 17. It is an anabolic androgenic steroid that has been developed for veterinary use. | boldenone |
| dromostanolone | | metholone |
| fluoxymesterone | | fluoxymesterone |
| metribolone | A synthetic non-aromatisable androgen and anabolic steroid. It binds strongly to the androgen receptor and has therefore also been used as an affinity label for this receptor in the prostate and in prostatic tumors. | 17beta-hydroxy-17-methylestra-4,9,11-trien-3-one |
| nandrolone | A 3-oxo Delta(4)-steroid that is estr-4-en-3-one substituted by a beta-hydroxy group at position 17. | nandrolone |
| oxandrolone | | oxandrolone |
| stanozolol | An organic heteropentacyclic compound resulting from the formal condensation of the 3-keto-aldehyde moiety of oxymetholone with hydrazine. Like oxymetholone, it is a synthetic anabolic steroid. It has both anabolic and androgenic properties, and has been used to treat hereditary angioedema and various vascular disorders. It has also been widely abused by professional athletes. | stanozolol |
