Drostanolone Propionate ( Masteron) 200 mg/mL – 10 mL

Biochem Drostanolone Propionate 200 mg/mL – 10 mL

Biochem Drostanolone Propionate 200 mg/mL – 10 mL, also associated with the historical brand name Masteron, is an injectable anabolic-androgenic steroid containing drostanolone propionate, an ester of drostanolone.

Drostanolone is a synthetic derivative of dihydrotestosterone (DHT) with androgenic and anabolic properties. Drostanolone propionate was historically investigated and used in certain medical settings, particularly as a hormonal treatment for selected cases of advanced breast cancer in women.

Its propionate ester provides a relatively short release profile compared with longer-acting anabolic steroid esters, allowing drostanolone to enter the bloodstream following intramuscular injection.

This formulation is described as an oil-based injectable solution. The specific carrier oil for the Biochem product has not been confirmed.

1. Influences Protein Synthesis

Drostanolone has anabolic-androgenic properties associated with androgen receptor activation and the regulation of protein metabolism in androgen-responsive tissues.

2. Influences Muscle Tissue Metabolism

Drostanolone interacts with androgen receptors in skeletal muscle and may influence protein turnover and lean tissue metabolism. These pharmacological effects do not establish a proven therapeutic benefit for muscle development in healthy individuals.

3. Influences Nitrogen Balance

As an anabolic-androgenic steroid, drostanolone may affect nitrogen metabolism, a physiological process associated with protein maintenance and tissue function.

4. Exhibits Androgenic Activity

Drostanolone is derived from dihydrotestosterone and produces androgen receptor-mediated effects in various tissues. Its androgenic properties distinguish it from compounds with primarily estrogenic activity.

5. Has Historical Antineoplastic Applications

Drostanolone propionate was historically used in selected cases of advanced breast cancer. Its medical history reflects earlier hormonal treatment approaches rather than a currently established first-line therapy.

6. Provides a Relatively Short Release Profile

The propionate ester allows drostanolone to be released over a shorter period than many longer-chain anabolic steroid esters, producing a comparatively shorter duration of activity.

7. Does Not Directly Aromatize Into Estrogen

Drostanolone is a DHT-derived compound and is not converted into estrogen through aromatase. This characteristic does not eliminate the possibility of endocrine or other adverse effects.

Clinical outcomes vary between individuals, and nonmedical performance-related benefits have not been established through approved clinical indications.

Drostanolone propionate is an esterified form of drostanolone designed for intramuscular administration with a relatively short release profile.

Step 1 – Absorption Following Injection

Following intramuscular injection, drostanolone propionate is released from the oil-based depot and absorbed into the bloodstream.

Step 2 – Drostanolone Activation

Enzymatic hydrolysis separates the propionate ester from the drostanolone molecule, releasing biologically active drostanolone.

Step 3 – Androgen Receptor Interaction

Active drostanolone binds to androgen receptors in tissues including skeletal muscle, bone, and reproductive organs.

Step 4 – Androgenic and Anabolic Activity

Drostanolone influences androgen receptor-mediated processes associated with protein metabolism, cellular signaling, and tissue function.

Step 5 – Hormonal Metabolism

Drostanolone undergoes metabolic transformation and elimination through pathways associated with synthetic androgenic compounds. Because it is a DHT derivative, it does not undergo aromatization into estrogen.

Drostanolone propionate has a relatively short release profile compared with longer-acting steroid esters. Reliable human elimination half-life data are limited, and pharmacokinetic characteristics may vary according to formulation and individual factors.

Carrier oils serve as pharmaceutical vehicles in injectable anabolic steroid formulations.

Their functions include:

• Dissolving and carrying drostanolone propionate.
• Supporting absorption following intramuscular injection.
• Providing an oil-based depot for gradual drug release.
• Acting as a vehicle for the active ingredient.
• Supporting the release characteristics of the injectable formulation.

Carrier oils do not independently produce anabolic effects or stimulate muscle growth.
