A recent study involving chemical analyses of 44 different products sold and marketed as Selective Androgen Receptor Modulators on the internet revealed that quality control in this industry varies greatly from one company to the next.
Only 52% of the products tested contained the product advertised, 59% contained amounts that differed from the label, a shocking 39% contained other unapproved drugs, 25% contained substances not listed on the label, and 9% contained no active substance at all.

Selective Androgen Receptor Modulators are investigational compounds still awaiting FDA approval and are not dietary supplements.
At Sports Technology Labs we are chemical suppliers, not medical doctors, and our expertise is sourcing and quality control. Sports Technology Labs does not encourage or condone consumer use of SARMs products, they are for research purposes only.
Anecdotal reports and guides may not match those used in carefully designed medical research protocols and may pose a serious risk of adverse effects in users. Individual variables, comorbidities, and polypharmacy can also contribute significantly to the risk of health problems.
Selective Androgen Receptor Modulators should only be used under the supervision and direction of a medical doctor or designated research authority.
We strongly discourage the use of SARMs for performance enhancement in sports and bodybuilding, and warn against “bro science” and peer consensus when making decisions about health.
RAD-140 is a selective androgen receptor modulator (SARM) that binds to androgen receptors in muscle tissue and promotes muscle growth and strength.
RU-58841 is a non-steroidal antiandrogen (NSAA) that blocks the conversion of testosterone to dihydrotestosterone (DHT).
DHT is a more potent form of testosterone that is responsible for male pattern hair loss. By blocking DHT, RU-58841 can help to prevent or slow hair loss.
RAD 140, also known as tiramesine, is a selective androgen receptor modulator (SARM) with the chemical formula C19H24N2O2.
It is structurally similar to testosterone, but it has a higher affinity for the androgen receptor (AR) and a stronger androgenic effect than testosterone.
RAD 140 binds to the AR and activates it, leading to increased protein synthesis and muscle growth in animals. It also has anti-catabolic effects, meaning that it helps to prevent muscle breakdown.
RU-58841 binds to the melanocortin-4 receptor (MC4R) and inhibits its activity in animals. The MC4R is involved in regulating appetite and energy expenditure. By inhibiting the MC4R, RU-58841 can help to reduce appetite and increase energy expenditure.
