Mastodex Propionate 100 Sciroxx is perhaps one of the more exotic androgenic / anabolic steroids that may be used by an athlete. Originally it was developed and used as an anti-estrogen for the treatment of breast cancer. It was largely used in combination with the SERM (Selective Estrogen Receptor Modulator) Tamoxifen (Nolvadex) for the treatment of breast cancer, and did give a significant decrease in estrogen levels in women undergoing such treatment. It is not much used these days for such purposes, for varying reasons, however for many athletes including competitive bodybuilders in particular, Mastodex Propionate 100 remains a rather unsung favourite of anabolic steroid medicines.

The fact that Drostanolone Propionate was being used as an anti-estrogen goes to suggest quite a lot about some properties Mastodex Propionate 100 possesses. Drostanolone Propionate is a derivative of DHT (dihydrotestosterone) and does not convert to estrogen through means of aromatisation. It is thought that the anti-estrogenic properties of Mastodex Propionate 100 may be in part to do with either an inhibition in some way of the aromatase enzyme or an interaction with estrogen itself in a way which blocks receptor binding of the estrogen. Either way, this would put Drostanolone Propionate as a useful tool for the anabolic steroid user who uses compounds that convert to estrogen (which most anabolic steroid users do, considering testosterone is the main basis of most cycles).

Sciroxx Mastodex Propionate 100 Dosage

Mastodex Propionate 100 is no longer presents on the market for some years now. It’s a new product. Dosis as anabolic substance in bodybuilding:

  • Bodybuilders generally take 250-350 mg of Mastodex Propionate 100 a week, through two or three weekly injections of 100 mg. Because of its power the androgen Drostanolone Propionate should be used with special care by women, in order to avoid an excessive virilization ( no more than a single weekly injection 25-50 mg).

Mastodex Propionate 100 Side Effects

Mastodex Propionate 100 will not cause bodybuilders problems related to gynecomastia and water retention (except for exaggerated doses). Liver toxicity should also not be a problem if sticking to correct dosage. Drostanolone Propionate side effect comes from the basic androgenic properties of dihydroTestosterone, including oily skin, acne, body and facial hair growth, aggression and problems related to pattern male baldness.
