Testolone (RAD140) is a selective androgen receptor modulator (SARM) that is still under development by Radius Health Inc. RAD140 is one of the newest SARMS, and its objective is to give a blast of testosterone without the negative side effects associated to steroid use. Hence the reason it is an alternative to testosterone replacement therapy. Specifically, it has been shown to interact with hormonal receptors in the tissues in the same way as a large doses of testosterone do. Furthermore, it also exhibited a greater anabolic effect than testosterone, and a more reinforced effect as well.
There are several groups of individuals who can benefit from Testolone (RAD140) use:
- Those who have low testosterone because of health issues, or prior abuse of anabolic steroids.
- Bodybuilders who want to bridge between steroid cycles. Imagine being able to use testosterone in between your existing anabolic steroid cycles without worrying about suppression and damaging your HPTA. This will allow you to keep more strength and muscle off cycle then you ever have before.
- Those who want to use a performance enhancing drug, but are concerned with the possible side effects. In such situation, one could cycle RAD140 instead of anabolic steroids and not worry about shutdown or the negative health effects caused by steroids.
- Those sensitive to gynecomastia. RAD140 is like using testosterone, but without the risk of estrogenic side effects because it does not aromatize into estrogen. Therefore, if a testosterone base is needed during a cycle, RAD140 can be used without fear of getting bitch tits or bloating.
Due to the fact that Testolone (RAD140) is so new and is still in Phase 1 of trials, studies on this SARM are few. However, so far it has been shown to increase endurance, stamina, and speed during an athlete’s training. Obviously, it is capable of increasing strength and muscle volume in a much shorter time, especially in those who are deficient in the male hormone testosterone. Moreover, RAD140 has anti-catabolic properties, so it will be a great help at preventing muscle wasting problems.
Up to the date, RAD140 did not show any side effects in studies. This means that there is no need to be concerned about estrogen, progesterone, or prolactin related side effects. Additionally, suppression has been shown to be minimal compared to testosterone. However, keep in mind that this is a very new drug, and it is wise to keep an eye on user results over the next year or two.
RAD140 can be dosed at 20-30 milligrams (mg) per day, and thanks to a relatively long half life, you can get away with only once a day dosing schedule. Regarding the possible cycle duration's, RAD140’s length of use can vary from 6 to 12 weeks.
