FAQs on our MK-677, Ostarine, and RAD-140 stack

What is MK-677, and how does it work?

MK-677, also known as ibutamoren, is a non-steroidal selective androgen receptor modulator (SARM) that works by stimulating the release of growth hormone (GH) from the pituitary gland. GH is a naturally occurring hormone that plays a key role in muscle growth, fat loss, and bone mineralization. By increasing GH levels, MK-677 can help to promote these effects.

What is Ostarine, and how does it work?

Ostarine is a selective androgen receptor modulator (SARM) that works by binding to androgen receptors in muscle tissue. This binding activates androgen signaling, which promotes muscle growth and strength. Ostarine is also known for its ability to preserve muscle mass during periods of caloric restriction.

What is RAD-140, and how does it work?

RAD-140, also known as tiramesine, is a selective androgen receptor modulator (SARM) that is structurally similar to testosterone. RAD-140 binds to androgen receptors in muscle tissue and promotes muscle growth and strength. It is also known for its ability to increase endurance.

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 significantly 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. It is critical when performing research with SARMs to only purchase the highest quality, verified by third-party analysis.

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.
