Nandrolone Decanoate
Also known as: Deca, Deca-Durabolin, Nand Deca
Nandrolone Decanoate is one of the most popular anabolic steroids in history, widely studied for both therapeutic and performance enhancement applications. It is known for promoting significant lean mass gains, improving collagen synthesis, and providing joint relief. It has legitimate medical uses in treating anemia and wasting conditions.

Mechanism of Action
Nandrolone binds to androgen receptors with high affinity and is converted to dihydronandrolone (a weaker androgen) by 5-alpha reductase, making it less androgenic than testosterone in tissues like the scalp and prostate. It also stimulates collagen synthesis and increases bone mineral density. It aromatizes at roughly 20% the rate of testosterone.
Dosing Research
Performance enhancement dosing ranges from 200-600 mg per week, injected once or twice weekly. Therapeutic dosing for anemia and wasting is typically 50-200 mg every 2-4 weeks. Cycles are typically 12-16 weeks due to the long-acting decanoate ester. Always run alongside a testosterone base.
Side Effects & Risks
Progesterone-related side effects including potential gynecomastia and libido issues ('Deca dick'). Cardiovascular strain through negative lipid changes. Suppresses natural testosterone production heavily and for extended periods. Joint relief is a notable positive side effect. Lower androgenic side effects compared to 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.
