Testosterone Propionate
Also known as: Test P, Test Prop
Testosterone 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.

| Molecular Formula | C22H32O3 |
| Class | Steroid |
| Category | Classic Steroids |
Mechanism of Action
The propionate ester is rapidly cleaved after injection, releasing free testosterone with a half-life of approximately 2-3 days. Testosterone then binds androgen receptors to exert its anabolic and androgenic effects on target tissues.
Dosing Research
Typically dosed at 50-100 mg every other day or 100 mg every day for performance enhancement. Due to its short half-life, injections every other day or daily are recommended to maintain stable blood levels. TRT use is less common due to injection frequency requirements.
Side Effects & Risks
Same side effects as other testosterone esters but injection site pain and irritation are more common with propionate. Estrogenic and androgenic side effects are present but may be easier to manage due to faster clearance. Water retention tends to be less pronounced than with longer esters.

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.
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.
