Mastelad 100 mg/ml (Drostanolone Propionate) 10ml vial

Drostanolone Propionate (Masteron) has a high androgenic effect and a moderate anabolic effect. Drostanolone propionate does not aromatize in the body (i.e. it does not transform into estrogen), rather it is a mild aromatase inhibitor. It has a biological action similar to dihydrotestosterone, since it is a derivative of this hormone.

In medicine, Drostanolone propionate is used as a treatment for breast cancer in women, however, due to the high probability of virilization, it is currently rarely used. Drostonolone is not susceptible to the action of aromatase, meaning there is no way to convert it into estradiol.

It has a good affinity for androgen receptors not only in the muscles, but also in the prostate and scalp, hence the possible side effects: baldness, enlarged prostate, growth of hair on the body. Being a derivative of DHT, it inhibits the activity of estradiol in tissues, therefore it has indirect anti-estrogenic activity.

Among the psychological effects of this drug we note the “motivational boost” for training, which is highly appreciated by athletes who follow slimming diets, when they lack the strength and psychological decline due to the lack of carbohydrates.

Drostanolone propionate is popular in bodybuilding, as it does not cause fluid retention and has a slight diuretic effect, which improves muscle definition. It can be useful for athletes who want to increase the hardness and density of muscles, it is mainly used before competition. It allows you to obtain a sculpted athletic shape, thanks also to the fat burning effect of the drug. Practice shows that the Drostanolon cycle can reduce fat mass by 5-10% compared to the initial state.

Drostanolone propionate has a low anabolic index (compared to testosterone), which is why it burns fat so well, at the same time increases the risk of androgenic side effects: aggression, acne, baldness, prostatic hypertrophy and virilization in women.

DOSAGE:

The optimal effect of the drug is achieved using a dosage of approximately 300-500 mg per week. People on hormone replacement therapy can use it to reduce SHBG, since in terms of side effects it increases the amount of free testosterone in the blood. The drug is much easier to tolerate than stanozolol or other DHT derivatives used to reduce SHBG. For these purposes, using 75 to 200 mg of the drug per week, it is believed that drostanolone propionate is detected worse during doping control than other steroids. However, detection methods are constantly being improved, so keep this in mind.

FOREIGN PROFILE:

*- approximate drug concentrations at various dosages

It has a short-acting ether. Injections are usually performed every other day. This is one of the main disadvantages of using propionate.

It is believed that short forms of steroids are more suitable for cutting purposes, however these differences only become visible in pre-competition preparation with a low percentage of subcutaneous fat.

Peak activity of propionate occurs on the day of injection and gradually declines within 24-36 hours after injection.
