This is an injectable steroid that has higher androgenic activity in the body, and a lower anabolic response. This steroid is otherwise well known in the weightlifting community as Masteron. Mastebolin by Alpha Pharma comes in a 10ml vial with 100mg/ml of drostanolone propionate. This steroid is great for athletes that would like to add lean muscle and mass.

Effects: Some of the beneficial effects that Masteron offers are:

  • Burns fat at a rate 5-7% faster than the body normally would
  • Lean muscle and mass gains
  • Most muscle mass gains will be retained after the cycle ends
  • It inhibits catabolic processes
  • Increased energy and strength levels

Directions For Use: The recommended dosage to be injected is 400-500mg per week which needs to be split throughout the week into 3 doses. The cycle length recommended for drostanolone propionate is 5-6 weeks maximum. This is not recommended for females to take as it can lead to virilizing effects (the development of masculine traits in the user).

This steroid can be combined with other drugs to make the cycle more effective. If the athlete’s goal is to gain pure mass and muscle a good combination is gonadotropin and testosterone. If a drying cycle is preferred Winstrol and oxandrolone are a good choice for a combination. To know which dosages will work best it is advised that a sports physician is consulted.

Side Effect: Side effects will only usually occur if the recommended dosage and dosage length are exceeded. Some of the effects that users have noted in the past are due to aromatization which can lead to fluid retention, swelling and gynecomastia. To avoid these effects an aromatase inhibitor can be used during the cycle or after during the PCT if these symptoms are prevalent. Other side effects that have been noticed by users are aggression, balding, acne, and reduced prostate activity.
