Methapex 20 from Sixpex packs 20mg of Methandienone (Dianabol) into each tablet and usually comes in bottles of 100. 

This stuff is a C17-alpha alkylated steroid, tweaked from testosterone. It’s got a double bond at carbons 1 and 2, which tones down its androgenic punch, and a methyl group at carbon 17 so your body can actually use it when you take it by mouth. Sixpex made Methapex 20 for fast, noticeable gains—think serious muscle and strength, fast. You’ll feel it kick in quick, with a half-life of only 3 to 6 hours.

People use it during bulking cycles, mainly to pack on size and strength fast. It ramps up protein synthesis, helps your body hold onto nitrogen, and boosts glycogenolysis. Most folks stack it with injectable gear like Testosterone to get even better results in the off-season.

If you do it right—with enough food—expect to see 20 to 30 pounds of weight gain in just 4 to 6 weeks. You’ll get big jumps in strength, recover quicker, and hold more water in your muscles, so you look fuller. Because it converts moderately to estrogen, beginners who want fast changes usually love it.

Take Methapex 20 with food to keep your stomach happy. Since it doesn’t last long in your system, split your daily dose into two or three servings. Always run some liver support like TUDCA, and grab an aromatase inhibitor like Letropex to keep estrogen in check.

Here’s how people usually dose it:
Beginners: 20–30mg a day
Intermediates: 30–50mg a day
Advanced: 50mg or more a day

Don’t push it past 4 to 6 weeks. After your cycle, do post-cycle therapy—Clomid or Nolva works—and take at least six weeks off before you even think about another round.

Side effects? 
Yeah, there are some. Estrogen-related problems like gynecomastia, water retention, high blood pressure—so you’ll want an AI. On the androgenic side: acne, hair loss, maybe some mood swings. It’s tough on your liver, so keep an eye on your bloodwork. It can strain your heart and will suppress your natural testosterone, too. Not for women or anyone with liver or pre-existing health issues.
