  • What are SARMS?

    What are SARMS?

    Selective Androgen Receptor Modulators, commonly known as SARMS are as class of research chemicals that were discovered to have anabolic effects, through the action of binding to the androgen receptor. SARMS are often seen as a replacement to pharmacological use of anabolic steroids for conditions such as hypogonadism and muscle wasting diseases.

    One of the distinct advantages SARMS have over anabolic androgen steroids is the lack of androgen activity caused by these substances, as androgen substances often cause unwanted side effects in especially in females who can experience side effects such as deepening of the voice and abnormal hair growth.

    The effects of these chemicals within the human body have prompted clinical trials into their use in many other conditions as well. For example, MK677, which is not technically a SARM, rather a growth hormone secretalogue, is being cited in the use an alternative to expensive HGH therapy.

  • The legal status of SARMS

    The legal status of SARMS in the UK

    SARMS are not known to be considered illegal substances, and in most countries are classed as investigatory chemicals. These compounds are often employed as performance enhancing drugs by both athletes and bodybuilders. They are known to improve strength, recovery and bone density.

    Currently SARMS UK are prohibited by the World Anti Doping Agency as of 2008. This was a response to an alarming amount of athletes being found to have used these substances. Ostarine and Andarine as noted as examples in the WADA prohibited list.

  • The clinical use of SARMS

    MK677 Osteoporosis

    Clinical use of SARMS

    Currently there are no SARMS that are fully approved for clinical use, however, there are many studies currently being conducted on SARMS in their use. This process involves approval from a countries specific drug administration, in the US this is the Food and Drug Administration and the UK’s Medicines and Healthcare products Regulatory agency (MHRA).

    Initial discoveries of SARMS began in the late 1990’s, and the number of potential drug candidates has expanded greatly. A number of substances have researched pre clinical trials, while others have only been experimented in laboratory or vitro testing.

  • Detection in humans

    SARMs UK Drug Detection

    SARMS and drug detection

    It can be difficult to detect SARM use because of the lack of information about their metabolites and metabolism in the body. Currently urine samples are taken for liquid-chromatography-tandem mass spectrometry and known metabolites can be found.

    Currently there is proven testing in place for Ostarine, LGD 4033, Andarine and Cardarine.

  • Are SARMS supplements?

    Are SARMS supplements?

    SARMS are not approved for sale in food supplements, and sale for this purpose is not permitted.

    There have been many companies selling supplements, often sourced from the USA that include SARMS are ingredients. The law in the UK clear, if a product is labelled as a supplement and sold as such as contains non approved substances it is illegal.

    Sale of SARMS UK as research chemicals is not illegal, however, these are strictly for laboratory use.

    Maxmusclelabs does not endorse the use of SARMS in any type of athlete use or human consumption, we have provided this information to aid studies in these compounds.


SARMs and their affect on Bone Density

Selective Androgen Receptor Modulators or SARMs are designed to bind onto androgen receptors in human tissues, thereby enabling them to bind to the androgen and trigger the respective functions. Most tissues in the human body have androgen receptors. However, these receptors may not function as well as they should, which is primarily why you may be recommended one of the approved selective androgen receptor modulators. These are synthetic drugs. These are a type of steroid but they should not be confused with anabolic steroids. The latter type of steroids has a plethora of side effects. Selective androgen receptor modulators do not have random targets.

They do not bind to any and every receptor and have no influence on hormones other than what they are meant to target. Hence, when you go take selective androgen receptor modulators or SARMS UK, you would be able to target only the androgen receptors and enable them to bind to the androgen secreted in the body. This eliminates or averts the chances of a range of physiological side effects that are usually associated with anabolic steroids.

Many patients suffering from different kinds of arthritis and low bone density, also known as bone mineral density, are being recommended SARMs UK. SARMs have been used in the treatment of osteoporosis for some time now. Although SARMs have been around for over five decades, clinical trials and conclusive researches have been few and far between. In recent years, substantial studies have been undertaken and completed. There are enough clinical trials with conclusive findings to establish the correlation of SARMs and bone mineral density or bone density.

SARMs may help treat Osteoporosis

Clinical Studies involving SARMs are positive

The human growth hormone plays a quintessential role in treatments for bone density. Other hormonal treatments or therapies such as injection of testosterone have been tried and experimented with but they have several negative side effects, especially among the old who are already at risk of prostate problems. SARMs have been found to be effective at specifically targeting the bone tissues and muscle tissues, thereby strengthening them. SARMs can do this without having any other unpleasant or adverse effect.


Many studies have been conducted with SARMs UK. Merck Research Laboratories conducted a clinical trial with Ibutamoren MK 677. More than a hundred and eighty people above the age of sixty were treated with this drug. The treatment period varies between two and nine weeks. There was a double blind group and placebo group to assess the impacts in a controlled trial. Blood and urine samples of all subjects were tested to look for signs of reduction or increase in bone density. Those who were administered the drug had more serum osteocalcin and alkaline phosphatase in their blood, thereby proving that there was a noticeable increase in bone density. Their urine samples also had fewer markers indicating loss of bone tissue that gets mixed in the blood stream and is excreted through the urine. Higher levels of such markers indicate greater loss of bone tissues. Hence, the lower levels of such markers also proved an increase in bone density.

The Chemical Structure of the SARMs UK MK677The structure of MK677 is C27H36N4O5S

MK677 and its relation to SARMS UK

There are many such studies and clinical trials that have been conducted in many parts of the world. Many researchers are furthering their exploration of the entire spectrum of use of SARMs in UK. SARMs are already recommended to help prevent loss of muscle. People suffering from muscle wasting diseases have benefited with a controlled dosage of SARMs UK. Bone density can also be increased with similar controlled dosages and courses. Of course the exact type of SARMs that can be recommended to increase bone density should not be chosen randomly. Different aspects of the medical history of a patient should be considered.


SARMs can affect bone density positively

It is widely known that bone density suffers as a person ages or grows old. Disease and general deterioration of health also affect bone density. This is not very different from loss of mass, which is healthy muscle and not just volume which could also be fat. Bone density suffers the most when someone has a musculoskeletal problem. Injury, inadequate nutrition, weak bone structure, osteoporosis, age caused deterioration and brittle bones are some of the common causes of reduced bone density. There are many variables that can cause or contribute to worsening bone density. The specific cause can be identified only after a thorough diagnosis.


While diet ensuring adequate nutrition and lifestyle changes coupled with exercise and therapy can be helpful to restore bone density, these often fail to achieve the desired results because ageing people or the elderly do not respond well to such changes. A young person may benefit more from changes to lifestyle, diet and health. Anyone with chronic medical condition, lifestyle diseases and age against them will find it difficult to treat reduced or declining bone density. This is where direct hormone injections come into the picture.

University of Virginia, Charlottesville, Virginia 22908, USA.
Over 12 months, the ghrelin mimetic MK-677 enhanced pulsatile growth hormone secretion, significantly increased fat-free mass, and was generally well tolerated. Long-term functional and, ultimately, pharmacoeconomic, studies in elderly persons are indicated.
