SP Labs Masteron (Masteron) is an injectable steroid containing the propionate form of the active ingredient drostanolone. Drostanolone is a derivative (derivative substance) of dihydrotestosterone, 2a-methyl-dihydrotestosterone. Due to the elimination of the double bond between the 4th and 5th positions, drostanolone turned out to be practically unaffected by the action of aromatase, and hence the conversion to estradiol. Moreover, studies show that drostanolone has a sufficiently pronounced antiestrogenic activity. There is nothing strange in this, if we remember that the drug is a derivative of dihydrotestosterone, and DHT directly weakens the activity of estrogens in tissues (estrogens attach to the corresponding receptors, but do not activate them).
SP Masteron is a moderate androgen with pronounced anabolic properties. SP Masteron has a high androgenic activity and not a strong anabolic effect. It also does not aromatize in the body, or in other words, it does not transform into estrogen.
SP Masteron gained its popularity due to the absence of such consequences of the use of the drug as water retention in the body by drugs such as methandrostenolone, oxymetholone, methyltestosterone. Drostanolone is also characterized by a moderate diuretic effect. Based on the above characteristics of the drug, we can conclude that athletes taking Masteron, as a result, get beautiful relief muscles.
SP Masteron is of particular interest to athletes whose main goal is to increase the hardness and density of muscles during the competition. Take the drug immediately before the competition. As a result of using SP Masteron, athletes get the most expressive appearance of muscles. This effect is obtained not only due to the fact that Drostanolone does not retain water, increases the hardness and density of muscles, but also due to the fact that the anabolic also has a fat burning effect. In practice, SP Masteron reduces the amount of adipose tissue in the body by 5-7%.
Drostanolone has a positive effect on the increase in strength indicators, while the total mass is maintained, and excess body fat is reduced. All these qualities of SP Masteron are of particular interest to powerlifters. It is allowed to use the drug during the diet in order to preserve muscle mass and suppress catabolism.
