Drostanolone Enanthate (Drostanon E) 200 mg

Drostanon E (Drostanolone Enanthate) 200 mg is Utinon's long-ester drostanolone injectable, supplied as a 10 ml vial at 200 mg/ml. Drostanolone is a dihydrotestosterone derivative that does not aromatise, and the enanthate ester stretches release over one to two weeks. Each vial is sealed in a printed carton with a scratch-off authenticity code.

What Drostanon E 200MG Is

Drostanolone is a reduced androgen structurally related to dihydrotestosterone, with a methyl group at carbon two that slows metabolic breakdown. Because it is already reduced, it cannot be converted to oestradiol by aromatase. The enanthate ester adds a long lipophilic chain that prolongs release from the intramuscular depot. A 10 ml vial at 200 mg/ml holds 2,000 mg of drostanolone enanthate.

The History of Masteron E

Drostanolone was developed in the late 1950s and marketed in the 1960s as Masteril and Drolban, initially for breast-cancer palliation. It later became known in physique research as Masteron, shorthand for the dry, dense look associated with non-aromatising androgens. The propionate ester was the classic presentation; enanthate arrived later to reduce injection frequency while keeping the same pharmacological profile.

How It Works

After injection, esterases hydrolyse the enanthate ester gradually, releasing free drostanolone over roughly one to two weeks. Drostanolone binds the androgen receptor with high affinity and, because it does not aromatise, it does not raise oestradiol or cause oestrogen-driven water retention. It is metabolised in the liver and excreted mainly in urine. The long ester smooths the curve and reduces peak-to-trough variation compared with the propionate.

What the Research Shows

• Drostanolone was investigated in the 1960s and 1970s as endocrine therapy for advanced breast cancer.
• Its non-aromatising profile has made it a reference compound in androgen receptor binding studies.
• Enanthate esters produce markedly longer release than propionate esters.
• Contemporary interest centres on lean tissue and conditioning rather than mass.

Research Context

Drostanolone's clinical research was concentrated in breast cancer, where objective responses were documented in a subset of patients. Analytical work has characterised its urinary metabolites, and detection methods are well established. The long enanthate ester extends the detection window relative to propionate, which is relevant in anti-doping research. Its main research value today is as a non-aromatising comparator.

Strength, Pack and Authentication

Each millilitre contains 200 mg/ml of drostanolone enanthate, giving 2,000 mg / 10 ml in the 10 ml vial. The vial is sealed with a flip-off cap and boxed in a printed carton that states the compound, strength and volume. A scratch-off security code inside the box links the pack to Utinon's manufacturing records.
