What is Masteron Propionate?

Masteron Propionate (Drostanolone Propionate) is an injectable anabolic steroid originally developed to treat breast cancer in women. It became popular in bodybuilding for its ability to harden the physique and add definition without water retention. It's a go-to compound for cutting phases and pre-competition prep.

Quick Facts

How Does It Work?

Masteron Propionate binds to androgen receptors in muscle tissue, helping the body retain lean muscle while in a calorie deficit. It also acts as an aromatase inhibitor, which means it helps keep oestrogen levels in check and reduces water retention. The result is a harder, drier look without the bloat associated with other compounds.

What It's Used For

• Cutting cycles — preserving lean muscle while losing body fat
• Pre-competition hardening and definition
• Controlling oestrogen-related side effects when stacked with other compounds

What to Expect

Users typically notice a harder, more defined physique within a few weeks, especially at lower body fat levels. It won't add large amounts of mass, but the muscle you do have will look tighter and more vascular. It also has a mild strength-boosting effect that many users find useful during a cut.

Possible Side Effects

• Androgenic effects — acne, oily skin, accelerated hair loss in those prone to it
• Suppression of natural testosterone production
• Virilisation in women (deepening voice, body hair growth) at higher doses

Cycle & Dosage Notes

Masteron Propionate is typically run for 8–12 weeks, injected every other day due to its short half-life. It stacks well with Testosterone Propionate, Trenbolone Acetate, or Winstrol for a cutting cycle. PCT is required after the cycle to help restore natural hormone production.

Storage

Keep at room temperature (15–25°C), away from light and moisture. Leave in the original packaging.
