Manufactured by Axiolabs
Mastaplex 200 is Axiolabs' long-ester Drostanolone Enanthate, dosed at 200 mg/mL. Often referred to as "Masteron E," this DHT-derived anabolic is prized by physique athletes for its ability to enhance muscular hardness, density, and visual detail with a smoother injection schedule than propionate. The enanthate ester extends the release curve, making it easier to maintain stable levels with fewer weekly pins—perfect for longer, refinement-focused phases.
Compared to propionate, the enanthate ester provides a slower, steadier release. You still get the classic "dry" look associated with drostanolone—minimal aromatization, crisp separation, and a tighter midsection feel when body fat is already moderate-to-low—but with lower injection frequency and more forgiving scheduling. This makes Mastaplex 200 an excellent choice for 8–12+ week cuts, photoshoot preps, and recomposition blocks where consistency beats crash dieting.
Drostanolone is a DHT-derivative that binds androgen receptors without converting to estrogen. In practice, this supports:

Intermediate and advanced athletes who want the Masteron look—crisper lines, better shoulder-cap and quad separation, and a denser appearance—without EOD pinning. Mastaplex 200 is a "polisher" compound: it won't build sloppy weight but will refine what your diet and training already reveal. If you're serious about conditioning and prefer longer, controlled cuts, the long ester fits that rhythm.
With the enanthate ester, most athletes split injections 2x per week (e.g., Monday/Thursday) to keep levels smooth. Common performance ranges:
Typical cycle length is 8–12+ weeks. Because drostanolone does not aromatize, look-related swings tend to be easier to manage when the rest of the stack is sensible and sodium/sleep are dialed in.
Mastaplex 200 rewards precision. Expect the best results when:
Think of Mastaplex 200 as a refinement tool: if the diet is tight and sessions are progressive, the visual payoff is significant—clearer lines, better grain, and a tighter overall package.
Build cohesive stacks around Mastaplex 200 with complementary Axio products:
Although drostanolone is non-aromatizing, it's still androgenic. Potential issues include:
Because Masteron doesn't convert to estrogen, AI use should be guided by the rest of your stack and by lab work, not by Mastaplex 200 alone.
Late-cut phases, photoshoot or stage run-ups, and long recomposition blocks. If your body fat is already trending down, Mastaplex 200 helps lock in the visual: more pop, less puff. Its long ester also makes weekly planning simpler than propionate-based protocols.
Because it's a long ester, most users begin PCT roughly 10–14 days after the last Mastaplex 200 injection (adjust to the rest of your stack). Use bloodwork where possible to confirm readiness and fine-tune protocol details.
Each vial contains 10 mL at 200 mg/mL Drostanolone Enanthate in a sterile oil base. Store upright, protected from light and heat. The British Dragon store offers fast, discreet USA shipping with protective packaging to safeguard your order.
If you want the Masteron look with a calmer pin schedule, Mastaplex 200 is the move. It's the long-ester, consistency-first route to a harder, drier, more detailed appearance—especially when paired with a matching long-ester test base, disciplined nutrition, and structured training.
It's used to enhance muscular hardness, density, and visual detail during longer cuts or recomposition phases, especially when body fat is already moderate-to-low.
Most athletes inject twice per week (e.g., Monday/Thursday) to keep levels stable due to the long enanthate ester.
No. As a DHT derivative, drostanolone does not convert to estrogen, supporting a dry look. Any AI use should be based on the rest of the stack, not Mastaplex alone.
Neither is "better"—they fit different needs. Enanthate offers lower pin frequency and smoother scheduling; propionate offers faster onset and finer day-to-day control.
Yes. Drostanolone suppresses natural testosterone. Begin PCT ~10–14 days after the last injection (adjust to your full stack), and use labs where possible to tailor dosing.
