Nandrolone phenylpropionate (NPP) or nandrolone fenpropionate, sold under the brand name Durabolin among others, is an androgen and anabolic steroid (AAS) drug primarily used in the treatment of breast cancer and osteoporosis in women. It is given by intramuscular injection once a week.
NPP is converted to nandrolone in the body, which is the active form of the drug. It has a long elimination half-life in the body when administered by intramuscular injection. The duration of action is about a week and is applied every few days to once a week. The elimination half-life and duration of action of NPP is much shorter than that of nandrolone decanoate.
Boldenate 250 or boldenone undecenoate is an androgen and anabolic steroid (AAS) drug used in veterinary medicine, particularly in horses. It is given by intramuscular injection.
Boldenone undecylenate is a prodrug of boldenone. When administered by intramuscular injection, a depot is formed where boldenone undecylenate is slowly released into the body and subsequently converted to boldenone. The drug has a biological half-life of 14 days when administered by intramuscular injection.
Trenbolone hexahydrobenzylcarbonate or trenbolone cyclohexylmethylcarbonate is a synthetic injectable anabolic-androgenic steroid (AAS) of the nandrolone group and an androgen ester – specifically the C17β hexahydrobenzylcarbonate (cyclohexylmethylcarbonate) ester of trenbolone.
Trenbolone hexahydrobenzylcarbonate has an activated elimination half-life of about 14 days, of about 14 days.
Trenbolone enanthate is a synthetic and injected anabolic-androgenic steroid and a derivative of nandrolone that was never marketed. It is the C17β enanthate ester and a long-acting trenbolone prodrug.
This ester gives trenbolone an active elimination half-life of approximately 8 days.
Stanozolol 50mgStanozolol 50mg is an androgen and anabolic steroid (AAS) drug derived from dihydrotestosterone (DHT). It is used in the treatment of hereditary angioedema.
It has been reported to have a biological half-life of 24 hours when given by intramuscular injection as an aqueous suspension.
Testosteron Enanthate, esas olarak erkeklerde düşük testosteron düzeylerinin tedavisinde kullanılan androjen ve anabolik steroid bir ilaçtır. Ayrıca transseksüel erkekler için hormon tedavisinde de kullanılır.
Testosterone enanthate has an elimination half-life of 4.5 days and a mean residence time of 8.5 days when used as a depot intramuscular injection. It requires frequent administration approximately once a week, and with it large fluctuations in testosterone levels occur, the levels initially rise and become above physiological.
Testosterone cypionate is an androgen and anabolic steroid drug primarily used for the treatment of low testosterone levels in men. It is also used in hormone therapy for transgender men.
Depo intramüsküler enjeksiyon yoluyla testosteron cypionate’in farmakokinetiğinin, eliminasyon yarı ömrü ve etki süresi de dahil olmak üzere, testosteron enantatınkiyle son derece karşılaştırılabilir ve dolayısıyla esasen aynı olduğu söylenir. Testosteron cypionate’in yarı ömrü en uzun olanlardan biridir ve yaklaşık 8 gündür. Testosteron cypionate, diğer testosteron analoglarına kıyasla kas içi uygulamadan sonra daha düşük bir klirens oranı sunar.
Testosteron Sustanon, bir androjen ve anabolik steroid ilacı ve karışık testosteron ester preparatlarının bir bileşeni olarak kullanılan bir testosteron esteridir.
Different testosterone esters provide different elimination half-lives in the body. Esterification of testosterone produces a sustained but non-linear release of the hormone testosterone from the injection depot into the circulation.
