Masteron 100

Masteron 100 by Dragon Pharma

Masteron 100 (Drostanolone Propionate) by Dragon Pharma is a precision cutting steroid trusted by competitive bodybuilders, physique athletes, and fitness models. Its reputation is built on delivering dry, hard muscle definition without the smoothness or water retention caused by estrogenic compounds. Perfect for the final weeks before competition, photo shoots, or peak summer shape, it works best when body fat is already low and every detail matters.

Because it does not convert to estrogen, Masteron ensures a sharp, "granite-like" appearance that highlights muscle separation, vascularity, and density — making it a go-to for serious physique refinement.

What is Drostanolone Propionate?

Drostanolone Propionate is a synthetic anabolic–androgenic steroid derived from dihydrotestosterone (DHT). Its short propionate ester gives it a functional half-life of 2–3 days, requiring frequent administration for stable results. Initially developed for medical purposes, its exceptional cosmetic benefits quickly made it a bodybuilding favorite for hardness, definition, and preservation of muscle tissue in a calorie deficit.

As a DHT derivative, it cannot aromatize into estrogen, removing the risk of estrogen-related side effects like water retention or gynecomastia. This property is why it consistently appears in advanced cutting stacks.

Mechanism of Action Masteron 100

Masteron binds with high affinity to androgen receptors in muscle and fat cells. This activation triggers increased protein synthesis, nitrogen retention, and muscle preservation, while also supporting a leaner appearance through enhanced fat metabolism. Its DHT base ensures a potent androgenic profile that promotes hardness and detail without additional estrogen management needs.

The short propionate ester gives athletes control — dosing can be adjusted in the final days before stage or camera to achieve the perfect balance between muscle fullness and sharp definition.

How to Use

1. Dosage: 300–600 mg/week. Lower doses possible for mild refinement or stacking purposes.
2. Frequency: Inject every other day (EOD) or 3× per week for stable levels.
3. Cycle Length: 6–10 weeks, often as the final stage of a cut.
4. Preparation Tips: Works best at low body fat. Manage sodium, water, and carb intake for optimal results.
5. PCT: Begin ~2 weeks after last injection; use tamoxifen or clomiphene as appropriate to the full stack and bloodwork.
