Not quite clear on what you're asking brotha.
How often you WHAT should be?
Here is a brief summary of half lives and duration.....
Anabolic steroid half-lives vary depending on the compound and whether it is an oral or injectable preparation. The half-life is the time it takes for half of the drug to be eliminated from the bloodstream.
Injectable anabolic steroids
The half-life of injectable anabolic steroids is primarily determined by the ester attached to the testosterone molecule. The longer the ester chain, the longer the compound's half-life.
Steroid (Injectable) Common Half-LifeEsters
Boldenone Undecylenate (Equipoise)14 daysUndecylenate
Drostanolone Propionate (Masteron)3 daysPropionate
Methenolone Enanthate (Primobolan)10 daysEnanthate
Nandrolone Decanoate (Deca-Durabolin)6 daysDecanoate
Nandrolone Phenylpropionate (NPP)4 daysPhenylpropionate
Sustanon 250~15 days (combination)Propionate, phenylpropionate, isocaproate, and decanoate esters
Testosterone Cypionate8 days or ~12 daysCypionate
Testosterone Enanthate4.5–10 daysEnanthate
Testosterone Propionate0.8–4 daysPropionate
Testosterone Undecanoate (Aveed)~20–34 daysUndecanoate
Testosterone Suspension<1 dayNone (no ester)
Trenbolone Acetate3 daysAcetate
Trenbolone Enanthate10 daysEnanthate
Trenbolone Hexahydrobenzylcarbonate (Parabolan)10 daysHexahydrobenzylcarbonate
Winstrol (Stanozolol)24 hoursAqueous suspension
Oral anabolic steroids
Oral steroids have a much shorter half-life than most injectable versions, and they are also 17-alpha-alkylated to survive "first-pass metabolism" in the liver. This can cause liver toxicity.
Steroid (Oral) Common Half-Life
Anadrol (Oxymetholone)8–9 hours
Anavar (Oxandrolone)9–10 hours
Dianabol (Methandrostenolone)4.5–6 hours
Halotestin (Fluoxymesterone)8 hours
Proviron (Mesterolone)12 hours
Winstrol (Stanozolol)9 hours
Important considerations
Individual Variation: Factors like genetics, metabolism, body composition, and other health conditions can affect a drug's half-life in the body.
Detection Windows: The half-life is not the same as the detection window for a drug test. Steroid metabolites can be detected for weeks or months longer than the drug is active in the body. For example, Nandrolone Decanoate has a half-life of about 6 days, but can be detected for up to 18 months.
Medical Guidance: The use of anabolic steroids should only be done under the supervision of a medical professional for legitimate purposes, such as treating hormonal deficiencies.
