Drostanolone propionate is usually stacked with other products, such as testosterone propionate and trenbolone acetate for cutting cycles.

More About Drostanolone Propionate (Powder).

Without question, the effects of drostanolone propionate (masteron) will be displayed in the most efficient way during a cutting cycle. However, for the effects to be truly appreciated the individual will need to be extremely lean. This is why drostanolone propionate (masteron) will most commonly be found at the end of bodybuilding contest prep cycles as the individual should already be fairly lean at this stage. The added drostanolone propionate (masteron) will help him lose that last bit of fat that often hangs on for dear life at the end of a cycle. Drostanolone propionate (masteron) will also ensure his physique appears as hard as can be.

Of course, the anti-estrogenic effect will simply enhance this overall look. For those that are not competitive bodybuilder lean, it is possible that the effects of Masteron may not be all that noticeable. The individual who is under 10% body fat should be able to notice some results and produce a harder, dryer look, but much over 10% and the effects may not be all that pronounced. As a potent androgen, Masteron can benefit the athlete looking for a boost in strength. This can be a very beneficial steroid for an athlete who is following a calorie restricted diet in an effort to maintain a specific bodyweight necessary for his pursuit. The individual could easily enjoy moderate increases in strength and a slight improvement in recovery and muscular endurance without unwanted body weight gain.

As a bulking agent, the effects of drostanolone propionate (masteron) will prove to be rather week. It is possible the hormone could provide gains in mass similar to Primobolan Depot, which won’t be that strong either, if the total dose was high enough. However, the relative gain in size will be very moderate with many anabolic steroids being far more suited for this period of steroidal supplementation. There are those who may wish to include drostanolone propionate (masteron) in a bulking plan for its anti-estrogenic and fat loss effects. The latter would ensure they kept their body fat gain minimized during off-season bulking phases, but this isn’t reason enough to use it in this phase. Body fat should be controllable without it.

As for the anti-estrogenic effects, off-season cycles are normally comprised of large amounts of aromatase activity due to high doses of testosterone. Progesterone activity is also commonly high with the addition of Nandrolone compounds and possible Trenbolone. Consider additional Anadrol or Dianabol and this estrogenic activity can become very pronounced. Unfortunately, while possessing anti-estrogenic effects, Masteron will not be strong enough to combat this level of estrogenic activity.
