FAQs for RAD–140 and LGD–4033 Stack

What is the chemical structure of LGD-4033?

LGD–4033, also known as Ligandrol, is a nonsteroidal androgen receptor (AR) modulator (SARM) with the chemical formula C19H22F3N3O. It is structurally similar to testosterone, but it does not bind to the AR as tightly. This means that it has a lower affinity for the AR and a weaker androgenic effect than testosterone.

What is the mechanism of action of LGD-4033?

LGD–4033 binds to the AR and activates it, leading to increased protein synthesis and muscle growth. It also has anti-catabolic effects, meaning that it helps to prevent muscle breakdown.

What is the chemical structure of RAD-140?

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 AR and a more substantial androgenic effect than testosterone.

What is the mechanism of action of RAD-140?

RAD–140 binds to the AR and activates it, leading to increased protein synthesis and muscle growth. It also has anti-catabolic effects, meaning that it helps to prevent muscle breakdown.

What to stack with LGD-4033?

LGD-4033 is commonly stacked with RAD-140 to enhance research outcomes.

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.
