Mast P 100 is an injectable steroid which contains the hormone Drostanolone Propionate. The preparation comes in vial of 10ml and contains 100 mg of Drostanolone Propionate per ML.
Drostanolone Propionate is most commonly used by bodybuilders who are in the “cutting” phase of their training and dieting. While only mildly anabolic, Mast P 100 extremely androgenic and because of this, brings about a very pronounced amount of hardness and definition to the muscles. On top of this, Mast P 100 is also 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. These effects are also noted by bodybuilders who choose to use the oral preparation of Masteron, Proviron.
Bodybuilders looking to incorporate Mast P 100 into a cycle might stack it with other steroids such as Trenbolone, Testosterone Propionate, and oral compounds such as Stanozolol or Halotestin to bring about an even more pronounced amount of definition and hardness leading up to a contest.
Common androgenic side effects are possible with Mast P 100, such as oily skin and increased libido. Due to its extremely androgenic properties, Mast P 100 is not a favorite among women bodybuilders, although most serious competitors still choose to use it due to its effectiveness as a pre-contest drug. Males typically use a dosage of Mast P 100 ranging from 300-600mgs per week while women typically prefer a dosage range of 100-300mg per week. Mast P 100 is often injected once every 2-3 days to help maintain consistent blood levels.
