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

If you are trying to figure out where to buy SARMs stacks, there appears to be no shortage of options out there. Sports Technology Labs is the best place to buy SARMs online because of their consistent, verifiable high quality products, safe bottling and packaging, fast shipping, and great customer service.

When you buy SARMs from Sports Technology Labs you are choosing the highest quality ingredients. Minimum 98% pure compounds tested and certified by accredited American third party labs, suspended in USP grade (the highest grade) PEG400, bottled in America.

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 human health

FAQs MK-677 Cardarine SR-9009 Stack

  • MK-677, also known as ibutamoren, is a non-steroidal selective androgen receptor modulator (SARM) with the chemical formula C24H31NO5.
  • Cardarine, also known as GW501516, is a peroxisome proliferator-activated receptor (PPAR) agonist with the chemical formula C12H10F6N2O.
  • SR-9009, also known as stenabolic, is a rev-erbα agonist with the chemical formula C19H18F2N2O2.
  • MK-677 binds to the growth hormone secretagogue (GHS) receptor and stimulates the release of growth hormone (GH) from the pituitary gland. GH promotes muscle growth, fat burning, and bone mineralization.
  • Cardarine binds to the PPARα and PPARδ receptors and activates them. PPARα and PPARδ are involved in the regulation of gene expression, including genes involved in fat metabolism.
  • SR-9009 binds to the rev-erbα receptor and inhibits its activity. Rev-erbα is a transcription factor that regulates the expression of genes involved in metabolism. Inhibiting rev-erbα can increase metabolism and muscle growth.

No, there are currently no ongoing clinical trials investigating the effects of stacking MK-677, Cardarine, and SR-9009. This is because these compounds are not approved for human use and there is limited safety data available. More research is needed to determine the safety and efficacy of these products and this stack was created based on customer feedback on frequently purchased products together.
