RAD-140 is an experimental selective androgen receptor modulator that has an anabolic to androgenic ratio of 90:1- meaning it has almost the same anabolic effects of pure testosterone with 1/100th of the androgenic side effects (testosterone has a rating of 100:100).  This is a positive as most of the negative side effects of testosterone, including effects on liver, kidney and prostate, come from its androgenic effects while making it the most potent anabolic SARM discovered to date!


All our SARM's are laboratory tested and we publish the certificates of analysis to ensure our product quality. We have strict standards for the specifications of our products and they are not released to the public without meeting these specs. The Certificates of Analysis are available on the bottom of each SARM page for the lot of available of that product.


These SARMs are in a PEG (Polyethylene Glycol Solution) please inquire about any allergies.





Typical Dose Used

10mg (1.0mL) per day

It is recommended to add the SARMs into juice or a shake directly with dropper when administering doses.



Available in 30mL or 60mL amounts

Typical cycle lasts 8 weeks



16 Hours


Due to the potency of RAD-140 we do recommend using a Post cycle therapy due to very mild testosterone suppression. You can get ours here which is a tri-phase PCT that includes: Natural Testosterone Boosting Complex, Anti-Estrogen Complex, and a Liver detox blend.

Experimental Benefits

RAD-140 has shown experimental benefits associated with increases in testosterone. This includes


  • Increase in Fat-Free Mass
  • Easily beats other compounds such as LGD-4033 and MK-2866 when it comes to Building Mass & Strength.
  • Enhanced Muscle, Bone & Ligament Recovery
  • Increased Libido


RAD-140 has also shown  no effects on liver, kidneys, prostate, nor aromatase conversion (conversion of testosterone into estrogen). RAD-140 has been reported to cause potentially cause testosterone production suppression we recommend following with a post-cycle therapy once experimental doses have been administered. See here

What Are SARM's

Selective-Androgen-Receptor-Modulators are just that, they selectively bind androgen receptors. The idea behind these compounds are great; create a compound that binds androgen receptors on only muscle tissue and nowhere else. One of the biggest problems with androgens are the negative side effects from the androgen binding receptors in different places on the body such as your prostate or liver which can cause overgrowth or even increase the chance of cancer. So, SARMs are attempting to negate that by being compounds that only bind androgen receptors on muscle tissue (that's the Selective part)- you get growth in your muscle but not in other organs.


These are experimental compounds which have not been deemed approved for consumption, but they are avaialble for research purpose. Take a look at the science listed to get an idea!

SARM's Specifications

*SR9009 has a short half-life of about 2.5 hours so we recommend splitting your doses into 2 doses taken evenly spaced out in the morning and evening. SARMs should be mixed with a beverage or shake for administering 

The Science

Selective Androgen Receptor Modulator RAD140 Is Neuroprotective in Cultured Neurons and Kainate-Lesioned Male Rats

"RAD140 was shown to exhibit peripheral tissue-specific androgen action that largely spared prostate, neural efficacy as demonstrated by activation of androgenic gene regulation effects, and neuroprotection of hippocampal neurons against cell death caused by systemic administration of the excitotoxin kainate. These novel findings demonstrate initial preclinical efficacy of a SARM in neuroprotective actions relevant to Alzheimer's disease and related neurodegenerative diseases."

Androgens Increase Survival of Adult-Born Neurons in the Dentate Gyrus by an Androgen Receptor-Dependent Mechanism in Male Rats

"Together these studies provide complementary evidence that androgens regulate adult neurogenesis in the hippocampus via the AR but at a site other than the dentate gyrus. Understanding where in the brain androgens act to increase the survival of new neurons in the adult brain may have implications for neurodegenerative disorders."

Selective Androgen Receptor Modulator RAD140 Inhibits the Growth of Androgen/Estrogen Receptor–Positive Breast Cancer Models with a Distinct Mechanism of Action

"RAD140 is a potent AR agonist in breast cancer cells with a distinct mechanism of action, including the AR-mediated repression of ESR1. It inhibits the growth of multiple AR/ER+ breast cancer PDX models as a single agent, and in combination with palbociclib. The preclinical data presented here support further clinical investigation of RAD140 in AR/ER+ breast cancer patients."
