Oxymetholone
Also known as: Anadrol, A-bombs, Oxy
Oxymetholone (Anadrol) is the most potent oral anabolic steroid available, originally developed to treat anemia and muscle wasting diseases. It produces the most rapid and dramatic mass gains of any oral steroid, with users commonly gaining 20-30 pounds in the first cycle. It is one of the few steroids that can directly stimulate erythropoietin production.

Mechanism of Action
A DHT-derivative with a 2-hydroxymethylene group. Despite being DHT-derived, it has significant estrogenic activity through a unique mechanism — it does not aromatize but may directly activate estrogen receptors. Dramatically increases red blood cell production. Has an anabolic rating of 320 and an androgenic rating of 45.
Dosing Research
Typical dosing ranges from 50-100 mg per day. Some advanced users go up to 150 mg per day but with significantly increased side effects. Cycle length should be limited to 4-6 weeks due to severe hepatotoxicity. Often used as a kickstart compound or for breaking through plateaus.
Side Effects & Risks
Severe hepatotoxicity — one of the most liver-toxic oral steroids. Causes dramatic water retention and bloating. Can cause gynecomastia through non-aromatase-mediated estrogenic activity (aromatase inhibitors may not fully prevent this). Significantly elevates blood pressure. Headaches and nausea are common. Can cause severe back pumps. Highly suppressive to natural testosterone.

Testosterone Enanthate
SteroidTestosterone Enanthate is one of the most widely used testosterone esters for hormone replacement therapy and performance enhancement. It features a long-acting enanthate ester that provides sustained release over approximately 1-2 weeks, making it one of the most convenient injectable testosterone formulations.
Testosterone Cypionate
SteroidTestosterone Cypionate is a long-acting testosterone ester very similar in pharmacokinetics to Testosterone Enanthate. It is the most commonly prescribed form of testosterone in the United States for hormone replacement therapy and is widely used in performance enhancement contexts.
Testosterone Propionate
SteroidTestosterone Propionate is a short-acting testosterone ester that requires more frequent injections than longer-estered variants. It provides faster onset and clearance, making it preferred for shorter cycles, contest preparation, or situations where rapid clearance is desired.
Oxandrolone
SteroidOxandrolone (Anavar) is one of the mildest and most well-studied oral anabolic steroids. Originally developed for medical use in burn patients, muscle wasting, and osteoporosis, it is valued in performance enhancement for producing lean, dry gains with minimal side effects. It is one of the few steroids prescribed to women and children in clinical settings.
