Mastabol 100 is an injectable drostanolone product with the short propionate ester, and the label on your vial reads “Di-Propionate”, which is a labeling error for propionate. Drostanolone is a synthetic androgen derived from dihydrotestosterone (DHT). It was first developed as a medicine to treat breast cancer in women, but those products were discontinued long ago. In strength-training literature, drostanolone is known as a finishing compound. It’s valued for a hard, dense look rather than size, since it doesn’t cause water retention. The propionate version is the faster of the two common forms. It starts working soon after injection and leaves the body sooner than the enanthate version in Mastabol Depot 200.
Mastabol 100 is drostanolone with a propionate ester attached, in an oil base. The propionate ester is short, so drostanolone is released into the bloodstream quickly and clears within a few days. Once the ester comes off, what’s left is active drostanolone. Drostanolone is a DHT derivative and isn’t 17-alpha-alkylated, so it avoids the liver stress seen with many orals. It doesn’t convert into estrogen. Each mL contains 100 mg, and the vial holds 10 mL.
It is an injectable drostanolone propionate product from British Dragon Pharmaceuticals, supplied as a 10 mL vial at 100 mg per mL.
They contain the same active ingredient, drostanolone. Masteron is the best-known name for it, and Mastabol is the British Dragon brand.
