Mastepex E200 from Sixpex is an injectable steroid—Drostanolone Enanthate, 200mg per milliliter, packed in a 10ml multi-dose vial.

What It Is
This stuff’s basically a long-acting form of DHT, with a seven-carbon enanthate chain that keeps it releasing steadily. Chemically, it’s Drostanolone Enanthate (C23H36O3). It doesn’t convert to estrogen, and it packs a high androgenic to anabolic punch (62:25 compared to testosterone). The carrier oil is usually grapeseed or MCT, and the half-life is about a week—sometimes a little longer. Doctors first used it for breast cancer, but these days, you mostly see it in bodybuilding circles.

Why People Use It
In medicine, it’s an add-on for treating breast cancer after menopause, thanks to its anti-estrogen effect. For bodybuilders, it’s all about cutting—guys use it to get that rock-hard, dry look, preserve muscle when calories get low, and really bring out definition before a show. It’s usually teamed up with things like Testosterone, Trenbolone, or Winstrol for that extra vascular, grainy finish.

What Makes It Stand Out
Drostanolone Enanthate delivers dense, hard muscle without bloating or gyno. It lowers estrogen and SHBG, which means more free testosterone when you stack it with other gear. You get more strength, more aggression in the gym, and you keep burning fat. If you’re prepping for a contest and want that 3D look—striations popping—this is a go-to. It’s also easier on the liver compared to most oral steroids. Further insights, including composition and usage context, are provided on buylegitgear.is.

Downsides and Side Effects
You’ve got the classic androgenic stuff: acne, hair loss if you’re prone to it, maybe your prostate acts up. Joints can feel a bit dry, and your good cholesterol (HDL) tends to drop. On the serious side, it can shut down your natural testosterone, strain your heart (blood pressure and LDL go up), and mess with your mood. For women, virilization is a real risk. If you don’t run testosterone with it, expect your libido to tank.

Dosing and How To Use It
For men, 400–800mg per week is the norm—split that into two shots, glutes or quads, using a 23–25 gauge, 1.5-inch needle. Run it for 8–12 weeks. It actually works with TRT at 200mg weekly. You don’t need an aromatase inhibitor since it doesn’t convert to estrogen. After your last injection, start PCT about 10–14 days later: Clomid (50/50/25/25) and Nolvadex (40/40/20/20). Always check your lipids and prostate markers with bloodwork.
