Masteron 100 by Dragon Pharma
What Is Masteron 100?
Masteron 100 is Dragon Pharma drostanolone propionate at 100 mg per mL - the classic Masteron, the finishing compound of bodybuilding. 1,000 mg per 10 mL vial.
Masteron is the definition of a dry compound: it does not aromatize, it sharpens muscle hardness and density, and it gives the stage-ready look in the last weeks before a show or a summer cut. The propionate ester is short, so it clears fast - which is exactly what you want when the goal is a crisp finish, not slow bulk.
Masteron 100 Dosage
Propionate is a short ester - injections every other day keep blood levels stable.
| Level | Weekly Dose | Per Injection (EOD) |
|---|---|---|
| Finishing | 300-400 mg | 0.75-1.0 mL |
| Classic Common | 400-500 mg | 1.0-1.25 mL |
Cycle Length
One 10 mL vial at 400 mg weekly lasts about 2.5 weeks - prep phases usually run 6-8 weeks, so plan 2-3 vials.

Masteron 100 Side Effects
Masteron is one of the mildest injectables on the estrogen side - its sides are the androgenic ones.
- Hair and skin - androgenic effects in prone individuals: shedding, acne, oilier skin.
- Estrogen - Masteron does not aromatize; some users report it even has an anti-estrogen feel at high doses.
- Cholesterol - watch lipids on longer runs.
- Suppression - still a steroid; PCT after the cycle.

What is Masteron?
Masteron 100 is Dragon Pharma drostanolone propionate at 100 mg per mL - the classic Masteron, the dry finishing compound of bodybuilding. 1,000 mg per 10 mL vial.
What does Masteron do?
It sharpens muscle hardness, density and definition without water - the stage-ready look in the final weeks of prep. It does not aromatize, so the finish stays dry.
Does Masteron lower estrogen?
Masteron does not aromatize, so it adds no estrogen of its own. At higher doses it is often described as having an anti-estrogen feel - one reason it is favored in the dry weeks of prep.
Does Masteron build muscle?
It is not a mass compound - the gains it supports are quality and density on an already lean base. Its role is conditioning and hardness, usually in the last 6-8 weeks before a show or summer.
How much Masteron 100 should I take?
At 100 mg/mL, the classic range is 300-500 mg weekly - 0.75-1.25 mL every other day. The propionate ester is short, so EOD injections keep levels stable.
How long does Masteron stay in your system?
Propionate is a short ester - it clears quickly compared with enanthate or decanoate versions. That fast clearance is exactly why it suits the final weeks of prep and a clean stop before competition.
What are Masteron side effects?
Mild on estrogen, demanding on the androgenic side: hair shedding and acne in prone individuals, and lipid shifts on longer runs. Suppression is real - PCT still applies.
