Why is Sports Technology Labs the best place to buy SARMs online?

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.

Abuse Warning

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.

FAQs RAD-140 and MK-677 Stack

Regular exercise, particularly resistance training, can stimulate GH release. Sleep deprivation, on the other hand, can suppress GH levels. Maintaining a healthy diet and lifestyle can also help to optimize GH production.

MK-677 binds to the ghrelin receptor in the hypothalamus, which is a region of the brain that controls GH release. By binding to this receptor, MK-677 mimics the effects of ghrelin, a hormone that stimulates GH release. This leads to increased GH levels, which can promote muscle growth, fat loss, and bone mineralization.

Research on MK-677 is still in its early stages, and more long-term studies are needed to fully understand its safety and efficacy. Additionally, MK-677 is not currently approved for any medical use,  as it classified as a research chemical.
