Masteron 200

Drostanolone Enanthate — Masteron 200 by Dragon Pharma

Masteron 200 is Dragon Pharma's long-ester formulation of injectable Drostanolone Enanthate at 200mg/ml — the same active compound as Masteron 100 bound to an Enanthate ester for twice-weekly dosing. Each 10ml vial in Dragon Pharma's MCT oil carrier delivers the identical dual mechanism of Drostanolone — intrinsic aromatase inhibition plus SHBG binding — on a long-ester schedule matched to Testosterone Enanthate or Cypionate cycles.

What Is Masteron 200 — Enanthate Ester Drostanolone

Masteron 200 contains the same Drostanolone molecule as Masteron 100 — same dual mechanism of androgen receptor activity combined with intrinsic aromatase inhibition and SHBG binding. The only difference is the ester: Enanthate instead of Propionate, extending the half-life from ~2-3 days to ~7-8 days. For a full explanation of how Drostanolone works — including why it functions as an internal AI and why it requires low body fat to reveal its aesthetic effects — see the Masteron 100 product page.

The Practical Case for Enanthate Over Propionate

The choice between Masteron 100 and Masteron 200 comes down entirely to injection frequency preference and the ester of the testosterone base being used:

• Masteron 200 (Enanthate) pairs naturally with Testosterone Enanthate or Cypionate — all compounds on a twice-weekly schedule, same injection days, same clearance timeline for PCT
• Masteron 100 (Propionate) pairs with Testosterone Propionate — every-other-day injections, faster onset, faster clearance
• Running Masteron 200 alongside a long-ester testosterone base eliminates the injection frequency mismatch that would occur with Masteron 100 alongside Enanthate — no need for separate EOD Masteron injections when the testosterone is only dosed twice weekly

Effects and Benefits

• Pronounced muscle hardness and density — same as Masteron 100, now on a twice-weekly injection schedule
• Intrinsic aromatase inhibition reducing estrogen from testosterone and other aromatising compounds
• SHBG binding increasing free testosterone availability from the cycle's testosterone component
• No aromatisation — no water retention or estrogenic side effects from Drostanolone itself
• Twice-weekly injection convenience matched to long-ester testosterone bases

Dosage and Administration

At 200mg/ml, a 1ml injection twice weekly delivers 400mg/week — a full working dose in a small injection volume. The higher concentration (200mg/ml vs 100mg/ml for Masteron Propionate) reflects the Enanthate ester's additional molecular weight and allows higher weekly doses with minimal injection volume.
