Drostanolone Propionate (Drostanon P) 100 mg

Drostanon P (Drostanolone Propionate) 100 mg is Utinon's short-ester drostanolone injectable, supplied as a 10 ml vial at 100 mg/ml. The propionate ester releases over two to three days, giving fast onset and fast clearance. Each vial is sealed in a printed carton with a scratch-off authenticity code.

What Drostanon P 100MG Is

Drostanolone propionate is drostanolone attached to a three-carbon propionate ester. The short chain is hydrolysed quickly, so free drostanolone peaks within days and clears shortly after the last injection. A 10 ml vial at 100 mg/ml contains 1,000 mg of drostanolone propionate. The compound is a reduced androgen and does not aromatise.

The History of Masteron P

The propionate was the original Masteron presentation, introduced in the 1960s for breast-cancer palliation. Its short release made it suitable for closely monitored clinical use, and it later became the standard drostanolone ester in pre-contest research, where a fast exit matters. The enanthate version followed as a longer-acting alternative for the same compound.

How It Works

Esterases cleave the propionate ester within two to three days, releasing free drostanolone. The hormone binds the androgen receptor and supports protein synthesis without converting to oestradiol, so water retention is minimal. Hepatic metabolism dominates clearance. Because the ester is short, the curve has a sharper peak and trough than enanthate, which allows rapid adjustment but requires more frequent administration.

What the Research Shows

• Propionate was the original clinical ester of drostanolone.
• Peak levels occur within a few days of injection.
• Short esters allow rapid washout before a defined endpoint.
• Non-aromatising androgens are studied for their effect on density rather than mass.

Research Context

The propionate is the flexible end of the drostanolone pair. Research comparing the two esters shows that the parent hormone is identical and only the release rate changes. That makes the pair useful for studying how exposure duration affects tissue response. In practice the short ester is chosen when a protocol needs to stop quickly; the enanthate is chosen when fewer injections matter more.

Strength, Pack and Authentication

Each millilitre contains 100 mg/ml of drostanolone propionate, giving 1,000 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.
