What sets this preparation apart
Propionate is the older Masteron presentation and the one most of the literature refers to, which is why a search for Masteron with no ester stated usually means this. It carries a single finished product assay, measured slightly above label at 109.22 mg/ml, and that is stated plainly rather than presented as equivalent to the enanthate's four reports.
Why this one
Propionate gives a 2 to 3 day release against the enanthate's four and a half. It is the older and more traditional Masteron presentation, and the one that appears in most of the literature, which is why searches for Masteron without a stated ester often mean this one.
What it costs
£34 for the vial. At 1000 mg of drostanolone in total that is £3.40 per 100 mg, which is the figure that compares against the other preparations.

Common questions
Why does the propionate have fewer lab reports than the enanthate?
It has one finished product assay against the enanthate's four reports across two laboratories. That is a real difference and worth knowing: both are tested, but the enanthate is tested more thoroughly.
What is the half-life difference between the Masteron esters?
Propionate releases over roughly 2 to 3 days and enanthate over roughly 4.5 days. The drostanolone delivered is identical; only the release curve differs.
How much drostanolone is in a vial?
A 10 ml vial at 100 mg/ml contains 1000 mg of drostanolone in total.
Has Masteron Propionate been independently tested?
Yes, 1 time. Analiza Bialek measured 109.22 mg/ml against a 100 mg/ml label.
How much does Masteron Propionate cost per 100 mg?
£34 for the vial, which holds 1000 mg, so £3.40 per 100 mg of drostanolone.
