Mast 250 is an injectable mildly anabolic but very androgenic steroid which contains the hormone Drostanolone Propionate often called Masteron. Because of its characteristics, it helps athletes’ bodies to obtain defined muscles.
Masteron, is noted as being an effective estrogen blocker, and also binds to SHBG, making it possible for other steroids being used to bind more easily to their respective receptors, thus making their presence in the body much more effective.
Mast 250 is often used in treatment of certain forms of breast cancer. It is called unique because it is not clinically used for weight gain.
In many cases athletes use Masteron as a preparation to combat estrogenic/progesteronic side effects, that’s mean that including Masteron in cycle, there is no need to use other ancillary drugs like such Arimidex or Letrozole. Masteron is not much toxic on liver too.
Between bodybuilders it is called Drostanolone Propionate, and is very popular steroid among competitive bodybuilders. Drostanolone Proprionate is a derivative of dihydrotestosterone, and that’s mean, it will not aromatize into estrogen. This make bodybuilders to consider it very useful and beneficial because aromatization causes excess water retention which may give the muscles a smooth appearance. Another thing that athletes take into consideration is as we said earlier it is strong androgenic, that can cause seemed results in density and hardness of muscle.
Mast 250 is often used by bodybuilders preparing for a drug-tested show. The substance drostanolone propionate is fast acting and quickly broken down. The athlete can therefore use Masteron up to about ten days before a drug test. For better results bodybuilders also use Masteron in combination with Tamoxifen, Stanozolole or Halotestin.
The middle dosage for men of Masteron is 100 mg injected every other day. It is best to inject Masteron every 2-3 days because it has a short duration of effect. Women typically prefer a dosage range of 100-300mgs per week.
There are cases when Masteron showed stronger androgen than everybody knows. In this cases it caused increased aggression.
Some possible side effects that can appear are following: oily skin. acne, accelerated hair loss and increased libido.
