Testosterone Cypionate
Also known as: Test C, Test Cyp, Depo-Testosterone
Testosterone 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.

Beginner| CAS Number | 58-20-8 |
| Molecular Formula | C27H40O3 |
| Class | Steroid |
| Category | Classic Steroids |
Mechanism of Action
Functions identically to other testosterone esters. The cypionate ester is hydrolyzed in vivo to release free testosterone, which binds androgen receptors and promotes anabolic processes including increased protein synthesis, nitrogen retention, and red blood cell production.
Dosing Research
TRT dosing typically 100-200 mg per week via intramuscular or subcutaneous injection. Performance dosing ranges from 250-500 mg per week for most users. Injection frequency is typically once or twice weekly due to its long half-life of approximately 8 days.
Side Effects & Risks
Side effect profile is essentially identical to Testosterone Enanthate. Includes estrogenic effects (gynecomastia, water retention), androgenic effects (acne, male pattern baldness), HPTA suppression, and potential negative impacts on lipid profiles and hematocrit levels.

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 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.
Nandrolone Decanoate
SteroidNandrolone 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.
