  • Testolone (RAD-140) powder | HQSARMS

    RAD-140 Testolone powder – 1000mg

    RAD-140, also known as testolone powder, is one of the strongest of the selective androgen receptor modulators (SARM) in terms of anabolic activity. Testolone works somewhat similar to testosterone but is more selective in the tissue it targets. Because it only binds to the androgen receptors in skeletal muscle, it does have many of the anabolic effects that are common in anabolic steroids like testosterone. The negative side effects are limited because it does not bind to the androgen receptors in organs anabolic properties

    Compared to SARMs like MK-2866 and LGD-4033, there is a limited amount of research on RAD 140. For instance, it has not been through clinical trials. The main source of information about this specific SARM comes from anecdotal evidence and user reports.

    RAD-140 results

    In this article you can find more info about the benefits and side effects of RAD 140.


    By targeting the androgen receptors in skeleton muscles, RAD-140 (Testolone) has the ability to increase muscle mass as well as strength without affecting the prostate or raising blood pressure. RAD 140 does not aromatize or convert to DHT. Therefore, it doesn’t come with the common negative side effects associated with androgenic anabolic steroids.


    When RAD-140 is used during a caloric deficit (for instance during a cutting cycle), it helps to prevent muscle wasting.


    As with all other SARMs, over time RAD-140 will improve the mineral density of your bones. You may even find that the compound prevents and aids recovery of previous bone injuries.


    Another benefit that is mentioned by a lot of users, is that they experience endurance and stamina enhancing.


    Although the side effects from RAD-140 are limited in comparison with those of anabolic steroids, they are not absent for all users. These side effects are consistent with higher testosterone levels:

    • Increased aggression.
    • Increased hair growth in women.
    • Increase in libido.

    RAD-140 and suppression

    Of all the SARMs known, RAD140 seems to cause the most amount of suppression of natural testosterone levels. When used in bodybuilding, a PCT is highly advisable in order to limit any negative side effects.

    Although testosterone levels will usually recover in a short amount of time, many users prefer to take some form of PCT after cycling on testolone, just to be on the safe side.

    Testolone dosage

    When used for the purpose of increasing muscle mass, the best dosage for RAD-140 lies between 5 and 20 mg per day. Most users go for a dosage of 10mg per day. A cycle of 8 weeks, followed by 2 or 3 weeks of PCT and 10 weeks off cycle is said to offer a lot of benefits with minimum side effects.

  • MK-2866 (Ostarine) powder | HQSarms

    MK-2866 (Ostarine) powder – 1000mg

    What is MK-2866?

    MK-2866, also known as ostarine is the most extensively researched and well-known selective androgen receptor modulators, or SARMS for short.

    Originally designed as a treatment for osteoporosis, researchers have discovered many more possible applications. It is currently under research to combat a number of different conditions.

    SARMS like ostarine (MK-2866) are specifically developed because they bind to he androgenic receptors (ARs) in more specific locations, mainly in bone and muscle tissue.

    Benefits of Ostarine

    MK-2866 is the safest and mildest SARM known. Therefore side effects seem to be pretty much non existent. The benefits of ostarine come from clinical research, as well as in the numerous anecdotal reports from users.

    Prevent muscle wasting

    First of all ostarine has the ability to prevent muscle wasting. This can have broad implications for the treatment of a whole range of illnesses that are known to cause a rapid loss of muscle tissue, but can also help in maintaining lean muscle mass during a caloric deficit.

    Improve bone health and density

    Combating the loss of muscle mass is by no means the only beneficial effect from this compound. It also has the potential to improve bone health by increasing bone mineral density. Ostarine was actually developed for the treatment of osteoporosis and other age related conditions that are known to cause a loss of bone mass. Based on the extensive research and anecdotal evidence, this compound seems to be very effective in this area.

    Improve recovery in injuries

    The most praised effect of ostarine is most likely the fact that it provides healing properties in injuries to bone and connective tissue. This means that it can improve recovery in fractures and other injuries in skeleton tissue.

  • Ibutamoren (MK-677) powder | HQSarms

    MK-677 Ibutamoren powder – 1000mg

    MK-677 powder, also known as ibutamoren or nutrobal, is an orally active, long acting growth hormone secretagogue. By mimicking the action of ghrelin, it increases the secretion of several hormones like growth hormone (GH) as well as insuline-like grow factor 1 (IGF-1).  What makes it a unique compound is the fact that it is the only effective alternative to HGH therapy that is orally active.

    Unlike general HGH therapy, Ibutamoren increases growth hormone levels but it doesn’t increase other hormones like cortisol. This is a major advantage because cortisol suppresses the immune system, reduces wound healing and impairs learning and memory.

    Benefits of Ibutamoren powder

    MK-677 increases muscle mass

    Ibutamoren boosts the levels of growth hormone (GH) as well as insuline-like grow factor 1 (IGF-1). These hormones are well known for having anabolic properties, meaning that MK-677 is able to increase muscle mass and improve strength, without affecting body fat. This effect is confirmed by clinical research as is shown in this study as well as this study.

    Enhanced recovery

    The positive effects of human growth hormone go well beyond simply increasing lean muscle mass. Growth hormone is essential for total recovery. The use of MK-677 provides for enhanced recovery by helping with tissue regeneration. Not only does it help with recovery after working out, but it can also help with injuries.

    Improved sleep quality

    Research has shown that many users notice a significantly improved sleep quality, mainly by affecting the sleep stage where rapid eye movement (REM) takes place. Because REM is essential for recovery, it seems obvious why this is considered a great compound for recovery.

    MK-677 stacked with other SARMS

    Ibutomaren has been shown to be most effective when used for an extended period of time, mainly because IGF-1 levels keep increasing as this compound is used longer. Much like HGH, it is often stacked with other SARMS or androgenic anabolic steroids. When combined with Ostarine (MK-2866) the effects on recovery are improved, while a stack with Ligandrol (LGD-4033) or Testolone (RAD-140) commonly mainly increases the muscle building effects.

  • LGD-4033 (Ligandrol) powder | HQSarms

    LGD-4033 (Ligandrol) powder – 1000mg

    What is LGD 4033?

    LGD-4033, also known as ligandrol, is a drug that belongs to a group of compounds that are known as SARMS, which is short for Selective Androgen Receptor Modulators. These compounds are being researched and developed as a possible safer alternative to anabolic–androgenic steroids (AAS) . Although classical anabolic steroids have proven to be of immense value in the treatment of a large number of illnesses they come with many unwanted benefits. SARMs like ligandrol (LGD-4033) are specifically developed because they bind to he androgenic receptors (ARs) in more specific locations, mainly in bone and muscle tissue.

    Benefits of  LGD-4033 Ligandrol

    The benefits of Ligandrol are much like those of Ostarine (MK-2866) but stronger. Apart from Ostarine, it’s also the only SARM that has been through human trials. Therefore there is a fair amount of clinidal data to backup the anecdotal evidence and user reports. The most important benefits of ligandrol are:

    Increase muscle mass

    One of the key benefits of ligandrol is it’s ability to increase muscle mass and strength. When used with a caloric deficit, it helps to maintain muscle mass.

    Improve bone density

    Beside the effect that Ligandrol has on limiting muscle wasting, it also has positive effects on bone health. By increasing bone mineral density, the strength of the bones is improved. One of the main goals in the development of LGD-4033 actually was the treatment of conditions that cause bone loss.

    LGD-4033 is classified as doping

    Because of its performance-enhancing effects, ligandrol is considered doping and therefore has been banned by WADA (World Anti-Doping Agency). A number of athletes have tested positive for the use of ligandrol.

  • YK-11 SARM powder | HQSARMS

    YK-11 powder SARM 1000 mg

    This powerful SARM is available as raw powder, as well as in liquid form.

    WHAT IS YK-11?

    YK-11 is one of the newest SARMs (Selective Androgen Receptor Modulators) that is currently undergoing research. Unlike other SARMs such as MK-2866, LGD-4033, and RAD-140, it is steroidal in nature. It is argued by some that this substance doesn’t quality as a SARM and that it’s just a synthetic anabolic steroid.

    YK11 closely resembles the structure of DHT (Dihydrotestosterone) and just like DHT, it is a partial agonist of the androgen receptor. Besides being a SARM, it is also a myostatin inhibitor. Myostatin also referred to as growth and differentiation factor-8 is a protein secreted in muscle tissues. It limits muscle cell growth.



    YK-11 is known for its ability to increase muscle mass. Apart from binding to the androgen receptors in muscle and bone tissue (like other SARMS) it also inhibits myostatin. Because myostatin limits muscle cell growth, inhibition increases muscle growth.

    Research results show that YK 11 simply aims to increase follistatin levels. Follistatin is another naturally occurring protein in the human body which helps keep myostatin in check.

    When follistatin is raised, myostatin level is lowered. YK11 binds itself to the androgen receptors inducing muscles that create more follistatin which reduces the levels of myostatin, a protein that limits the growth of skeletal muscle. The result is a whole lot of increased muscle mass.


    YK-11 does not only increase muscle mass but is also known for effectively boosting strength.


    Another benefit of YK-11 is that it helps to build stronger bones. This is important because stronger bones means a decreased chance of injuries.


    There is not a lot of info regarding the side effects of this SARM, simply because it is still early in its research phase. Our main source of information about the side effects of YK-11 is what is reported by users.


    The number one side effect is suppression of the natural testosterone production, which is at you would expect from a steroidal SARM. Most users end their cycle with a PCT.

  • S 23 Powder | HQSARMS

    S-23 powder – 1000mg

    At HQ Sarms you can buy high quality S-23 in powder form.

    What is S-23?

    S-23 is one of the newest SARMs (Selective Androgen Receptor Modulators) that is currently undergoing research. As it is still in the early stages of clinical research, most of what is known about this compound comes from anecdotal evidence. Based on user reports S-23 is most likely the most potent SARM that is currently known.

    Benefits of S-23

    Increase muscle mass

    The increasing popularity of S-23 comes from it’s ability to increase muscle mass in a highly effective way. Users claim that the muscle building effects from S-23 can be compared to those of anabolic steroids while the unwanted side effects are way less.

    Improve bone density

    SARMs like S23 offer unique bone health benefits thanks to their dual action: activating bone-building cells and increasing muscle strength. Based on the available research, it is able to improve bone density.

  • Stenabolic (SR-9009) powder | HQSARMS

    SR-9009 (Stenabolic) powder – 1000mg

    SR9009 is probably better known as stenabolic and it’s basically a synthetic drug that was developed for the purpose of studying the circadian rhythm. Research done on mice shows that Stenabolic can help lose weight, decrease cholesterol, inflammation, and anxiety.

    Although no official studies have been done on humans, there are a lot of user reports that show that this compound has very promising effects.

    What is SR-9009

    Stenabolic (SR-9009) is not a SARM like MK-2866 or LGD-4033 but actually a REV-ERB agonist. REV-ERBs are proteins that are responsible for balancing the body’s internal clock.

    Possible benefits of stenabolic (SR-9009)

    SR-9009 is sometimes called “exercise in a bottle” because it has effects that resemble the effect exercise has on our body.

    Increases endurance

    In one study that was conducted with mice, SR9009 was shown to significantly increase endurance within just 30 days of intake. Evidence shows that the mice were able to run longer distances for an extended period of time.

    Users mention an increase in endurance as one of the main benefits of stenabolic.

    Reduces blood cholesterol

    A study involving mice showed that Stenabolic can reduce total cholesterol and triglyceride levels in the blood when taken for a period of 7 to 10 days. Another study involving a group of genetically modified mice indicated that the SARM can lower triglycerides and bad cholesterol. This without affecting the good cholesterol.

    Decreases inflammation

    In one study, rats showed decreased lung inflammation after taking SR9009 thanks to a decreased production of TNF-alpha. The SARM also decreased inflammatory nerve cell molecules in these rats.
