Masteron Propionate 100 mg (Drostanolone) – Xeno US

The Ultimate Aesthetic Finisher & Anti-Estrogenic Agent

Masteron Propionate, also known by its active ingredient Drostanolone Propionate, is a highly effective anabolic/androgenic steroid derived from DHT (Dihydrotestosterone).¹ Originally developed to combat certain forms of breast cancer, it is widely utilized by bodybuilders as a potent ancillary drug in both bulking and cutting cycles.

Masteron is prized for its unique anti-estrogenic action in the body, which plays a role similar to Proviron by acting against estrogenic side effects like water retention. It is commonly used immediately prior to a competition to achieve the look of hard and brutal muscle density.

Key Benefits & Aesthetic Effects

• Maximum Muscle Hardness: The primary benefit of Masteron is its ability to create extremely hard and dense musculature, ideal for competition-level conditioning.

• Powerful Anti-Estrogenic Action: Masteron exhibits anti-estrogenic action in the body, helping to prevent estrogenic side effects such as water retention without needing a separate Aromatase Inhibitor (AI) in many cases.

• Low Liver Toxicity: The compound’s toxicity to the liver is very low, meaning you do not need to take any liver protection like Carsil or Milk Thistle.

• High-Quality Gains: Can be effectively used as a bulking factor to gain high quality muscle mass without water retention, particularly when combined with other select steroids.

• Optimal Results at Low Body Fat: To optimize Masteron’s effects, your body fat percentage must be at the lowest possible level for maximum visual impact.

Technical Specifications

Usage and Dosage

Owing to the short Propionate ester, injections must be highly frequent to maintain stable hormone levels.

• Injection Frequency: Injection should be made every other day (EOD).

• Weekly Dosage: The weekly dosage must be 300–500 mg per week (equivalent to 75–125 mg for every other day).

• Cycle Duration: Masteron can be used throughout 6–12 weeks, with 8 weeks being the most common duration.

Stacking Recommendations

• Cutting/Pre-Contest: Best combined with partners like Primobolan and Winstrol.

• Quality Mass/No Bloat: Commonly used with Nandrolone Decanoate (Deca) and Equipoise to ensure quality gains without water retention.

• Extreme Mass Gain: For more muscle gaining, combine with Dianabol and Testosterone for extreme muscle mass with very low levels of estrogenic side effects and water retention.

Side Effects Masteron

Masteron has a relatively small number of side effects, but users must be aware of its high androgenic rating:

• Androgenic Effects: Oily skin, acne, body/facial hair growth, and aggression.

• Accelerated Hair Loss: The most common drawback is accelerated hair loss (Male Pattern Baldness) due to its DHT derivation.

Note on Hair Loss: To attempt to avoid hair loss, you can take Proscar (Finasteride).
