Drostanolone propionateis an ester of drostanolone. Drostanolone is indicated in post menopausal women with recurrent breast cancer, in combined hormone therapy.Drostanolone causes retention of nitrogen, potassium, and phosphorus; increases protein anabolism; and decreases amino acid catabolism.
The antitumor activity of drostanolone appears related to reduction or competitive inhibition of prolactin receptors or estrogen receptors or production.
Masterone 100 USP injection provides drostanolone propionate, a potent androgenic steroid that has similar characterises of dihydrotestosterone. Drostanolone is incapable of aromization and therefore doesn’t convert into oestrogen. Both drostanolone’ anabolic and androgenic activity is far greater than methyl testosterone. The esterification of the 17-beta-hydroxyl group increases the duration of the action of drostanolone. Drostanolone esters in oil injected intramuscularly are absorbed slowly from the lipid phase, thus Masterone 100 can be administered at intervals of every 3-4 days.
Masterone 100 contains drostanolone propionate in a 10ml solution for injection (100mg drostanolone propionate / ml).
Masterone 100 is a yellowish oily solution for intramuscular injection.
