UK SARMS in Sport


SARMS UK & Swimming

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.

Are SARMS banned or illegal in UK or internationally?

Are SARMS UK banned

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 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.

US/UK SARMS clinical use

Currently there are no SARMS that are fully approved for clinical use, however, there are many studies currently being conducted 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.

How are SARMS detected in athletes?

SARMS UK 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 food supplements in the UK?

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 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.
