The anabolic:androgenic ratio of a steroid is a comparison of its anabolic (tissue-building) effects to its androgenic (masculinizing) effects.
Anabolic effects refer to the promotion of muscle growth, bone density, and red blood cell production, among other things, while androgenic effects are associated with the development and maintenance of male characteristics such as facial hair growth, deepening of the voice, and libido.
The ratio is typically expressed as two numbers separated by a colon (e.g., 100:100), where the first number represents the anabolic potency relative to testosterone, and the second number represents the androgenic potency relative to testosterone. For example, a steroid with a ratio of 500:500 would have equal anabolic and androgenic effects compared to testosterone.
| Steroid | Anabolic:Androgenic Ratio |
|---|---|
| Testosterone | 100:100 |
| Trenbolone | 500:500 |
| Nandrolone | 125:37 |
| Oxandrolone | 322:24 |
| Methandrostenolone | 90-210:40-60 |
| Stanozolol | 320:30 |
| Oxymetholone | 320:45 |
| Boldenone | 100:50 |
| Methenolone | 88:44 |
Please note that these ratios are approximate and can vary based on factors such as dosage, individual response, and other contextual factors. Additionally, the use of anabolic steroids should only be done under the supervision of a qualified medical professional.
