M-Sten, Methylstenbolone, MSten RX

MSten is on the list of compounds to be added to the Schedule III list.  It is still a high liver toxic steroid that has good mass building effects.  You can find this on occasion at a few retailers, but it is questionable whether you can find this and the prices are through the roof.  MSten should be taken with a liver support supplement and something to protect the heart.  It can cause toxicity to people who have a pre-existng condition or drink alcohol and heart damage for people with a high sugar diet, so be careful with this one.


MSten usually has a cycle length of about 8 weeks at the longest because it is so toxic. Dose is about 20-30mg per day for advanced users. It’s a good idea to run PCT with this as well and to have on support supplements to block estrogen.  MethylStenbolone can be taken at any time of the day since it lasts a long time in the body. It should be taken only by men over 21 and the averages gains are reported as 12-15lbs, most of which will be water but does appear to be muscle mass.  At $90 a bottle a cycle of MSten isn’t cheap, but if you can find it, it makes a viable anabolic steroid for men who wish to use such things.


Assault Labs, Iron Mag Labs, and a host of other underground supplement companies are selling a hormone called methylstenbolone.  Most companies market this as “MSten, MSten RX, Super M-Sten,” you get the point.  I always find it a bit concerning when ten companies have the same name for a product, MSten for example, and none of them go after one another or file copyrights.  I’m guessing that this is because most of these companies disappear just as quick as they come up.   M-Sten usually is dosed in between 4-10mgs per capsule.

has made quite an impact on the underground community, which is why I wanted to address it.  I will shed some light on what a user can expect while using something like this including muscle gains, strength, side effects, PCT, and other comparable steroids.

M-Sten is a DHT

derivative such as the steroids primobolan and masteron.  Because of its relationship with DHT, it will be a lean and relatively dry strength builder.  I say strength and not muscle because this compound will sway more on the strength gain side vs. the weight gain side.  It is still possible to put on a few good pounds of muscle with this stuff.   The underground community has embraced it as the new Holy Grail since the popular Superdrol was banned.   In my opinion, there are better, safer options out there, but to each there own.





MSten’s side effects

will be dose dependent as with many other hormones.  It will not aromatize, so estrogen sides will be low to non-existent.  The usual DHT side effects will be present including prostate problems, having trouble urinating, hair loss, aggression, and acne.  The most concerning of all is the 17a Dimethyl attachment to the hormone which is meant to increase the bioavailability of the hormone.  As with other methylated steroids such as anadrol, winstrol, and superdrol, Msten is very liver toxic and will increase internal inflammation.  This stuff can be dangerous and even deadly depending on dosing and your current liver health.  Expect an elevated liver panel across the board and low HDL (good cholesterol) numbers.  As always, blood work is a must if you are going to risk running a harsh compound such as methylstenbolone.

Most people are dosing this stuff at 8mgs per day and some go getters are taking upwards of 30mgs per day.  Until next time my friends…..


If you want to have a better prohormone alternative to MSten, look at Pr by Liquid Labs. This contains the LEGAL prohormone 1-Andro which has been shown to give up to 11lbs of mass gain in a 4 week cycle.  It is milder on the liver and cardiovascular system than MSten, but it is recommended that support supplements should be taken. Pr should be run at 2-300mg per day in divided doses.
