Steris Laboratories Mastabolin 100mg Injection (Drostanolone Propionate)

Mastabolin 100mg by Steris Laboratories contains Drostanolone Propionate, a fast-acting injectable anabolic androgenic steroid widely used during cutting cycles to achieve a hard, dry, and well-defined physique. It is especially popular among bodybuilders and athletes preparing for competitions due to its strong anti-estrogenic and muscle-hardening properties.

Drostanolone Propionate does not convert to estrogen, making it ideal for users looking to reduce water retention while maintaining lean muscle mass and vascularity.

• Enhances muscle definition and vascular appearance

• Helps reduce water retention

• Provides mild anti-estrogenic effects

• Supports fat loss during cutting phases

• Improves strength and muscle preservation

• Short ester allows quick results and control

Common Uses

• Cutting and contest-prep cycles

• Lean muscle maintenance during calorie deficit

• Stack support to reduce estrogenic side effects

Possible Side Effects

While generally considered milder than many anabolic steroids, side effects may occur, especially with improper use:

• Suppression of natural testosterone production

• Androgenic effects (acne, oily skin, hair thinning)

• Increased cholesterol imbalance (LDL/HDL)

• Injection site pain or irritation

• Mood changes or aggression in sensitive users

Note: Side effects vary based on dosage, duration, and individual response. Proper cycle planning and post-cycle support are important.
