Anabolic Steroids (AAS) are conventionally divided by their impact on the athlete's body. This page presents the most powerful steroids that have a huge anabolic effect on the body, i.e., when used correctly, in combination with a muscle mass-gaining diet, they can provide significant increases in muscle mass and strength.
Before deciding to use this category of anabolic steroids, you must clearly understand that these steroids are not intended for beginners, except in some cases and at low doses.
Moreover, the stronger the steroid, the higher the risk of side effects during its use. Additionally, you should understand that the use of the most potent AAS, and steroids in general, is not recommended if you do not have several years of natural training experience or if you have not previously used safer steroidal substances.
Ranking of the Most Powerful Steroids
This list ranks the most powerful steroids in ascending order, from the "weakest" to the most potent in their effect.
Oxymetholone (Anadrol)
Oxymetholone is considered the most powerful oral steroid among AAS used to enhance athletic performance. When using Anadrol, weight increases very rapidly, but athletes using this steroid note that most of the weight gained is due to fluid retention. Therefore, this steroid is often combined with Stanozolol, which allows for gaining quality muscle with minimal fluid retention in the tissues. It is highly toxic to the liver and significantly suppresses the production of natural testosterone. This steroid is not recommended for beginners. The duration of use should not exceed 6 weeks and should not be used more than a few times a year. Oxymetholone is often used as a mass-gaining booster with a smooth transition to other AAS. Generally, the maximum muscle gain effect is achieved within the first three weeks of use, then stabilizes.
Testosterone Preparations
Testosterone is considered the benchmark steroid. All other active ingredients in steroid drugs were synthesized from testosterone and its derivatives. Synthetic testosterone is the precursor to all steroids. The strength of testosterone and its esters (cypionate, enanthate, testosterone mixes) on the human body is directly proportional to the dosage used. The rule for testosterone is: the higher the dosage, the stronger the anabolic and androgenic effects on the body. "Long" testosterone esters are the basic (main) component of advanced cycles for both muscle mass gain and cutting for advanced athletes. The only drug on this list that can be used by beginners.
In my opinion, testosterone in the form of enanthate, cypionate, or propionate, depending on the athlete's age and goals, is the best choice for the first steroid cycle. Dosages range from 250-350 mg per week for beginners to 2-3 grams per week for professional athletes. To summarize: the strength of testosterone depends on the dosage. The higher the dosage, the better the result. However, in this case, the risk of "catching" side effects grows proportionally with the dosage increase. Due to high aromatization on the cycle, the use of anti-estrogens and hCG may be required on long cycles.
Trenbolone Preparations
Trenbolone and its esters and "mixes" are the most potent injectable anabolic steroids available today. Trenbolone's anabolic activity exceeds the anabolic and androgenic activity of testosterone fivefold. In addition to its ability to significantly promote muscle mass and strength gain, the drug does not aromatize, i.e., estrogen-dependent side effects do not occur. Also, the drug has unparalleled ability to bind to androgen receptors in both muscle and fat cells, effectively promoting fat loss. Trenbolone strongly suppresses the endocrine glands and natural testosterone production, so it is not recommended to use trenbolone without hCG. Trenbolone is recommended to be used in combined cycles along with testosterone in a ratio of 1 part trenbolone to 2 parts testosterone, which can be aimed at gaining quality muscle mass or cutting.
Halotestin (Fluoxymesterone)
Standing apart in the top of the most potent androgenic anabolic steroids is Halotestin. "Halo" is considered the strongest oral steroid. However, as we remember, the strength of the effect is directly proportional to the frequency of side effects. The steroid has an anabolic activity 19 times higher than testosterone and an androgenic activity 8.5 times higher than testosterone. However, in practice, in the human body, the anabolic properties of the steroid are close to zero, and all positive (as well as negative) effects are achieved due to its androgenic activity.
Therefore, athletes rarely use Halotestin in their practice. It is considered a highly specialized drug, best used directly two weeks before competitions. The steroid extremely affects androgen receptors, which in turn increases sports aggression, the desire to dominate, as well as strength, power endurance, and performance. It burns fat, which can be a good help in achieving muscle definition before performances. It is not recommended to use it for more than 4 weeks due to its high liver toxicity and extremely high risk of developing androgen-dependent side effects.
