The length of time steroids stay in your system depends on the specific type of steroid, the method of administration (oral or injectable), dosage, frequency of use, and individual factors such as metabolism. Detection windows for common anabolic steroids:

• Oral steroids generally have shorter detection times, often from a few weeks up to about 2 months.
• Injectable steroids tend to stay in the system much longer, from several months up to over a year in some cases.

Here are some examples of detection times for popular anabolic steroids:

Steroid| Half-Life| Detection Window
---|---|---
Anadrol (Oxymetholone)| 8-9 hours| Up to 2 months
Anavar (Oxandrolone)| 9 hours| Up to 3 weeks
Dianabol (Methandrostenolone)| 4.5-6 hours| Up to 6 weeks
Deca-Durabolin (Nandrolone Decanoate)| 6 days| Up to 18 months
Trenbolone Acetate| 3 days| Up to 5 months
Winstrol (Stanozolol)| 9 hours (oral), 24 hours (injectable)| Up to 2 months
Primobolan (Methenolone)| 4-5 days| Up to 5 weeks
Testosterone Enanthate| 8 days (injectable)| Up to 3 months

These detection windows reflect how long steroids or their metabolites can be found in urine or blood tests

. Testing methods and detection times:

• Urine tests are the most common and can detect steroids up to about 28 days depending on the steroid type and dosage.
• Blood tests detect steroids for up to 14 days.
• Hair and fingernail tests can detect steroid use over much longer periods, from several months up to a year or more, as steroids incorporate into keratin structures

Factors influencing how long steroids stay in your system:

• Type and chemical structure of the steroid
• Route of administration (oral vs. injectable)
• Dosage and frequency of use
• Individual metabolism, age, body fat, hydration
• Sensitivity of the testing method used

In summary, anabolic steroids can remain detectable from a few weeks to over a year depending on the specific steroid and usage pattern. Injectable steroids generally stay in the system much longer than oral steroids. Advanced testing methods like hair or fingernail analysis can extend detection windows significantly beyond urine or blood tests
