SARMs RAD 140, also known as Testolone, is one of several selective androgen receptor modulators (SARMs) that was initially developed as a potential alternative to testosterone replacement therapy. It should not be confused with it’s esterified form, RAD 150, also known as TLB 150.

RAD 140 binds to the androgen receptors (AR) in a selective manner and does not produce the full range of androgenic effects as similar substances like testosterone, DHT, or anabolic steroids.

High AR Binding Affinity of RAD 140

RAD 140 demonstrated excellent affinity for the AR (Ki = 7 nM), higher even than DHT and most anabolic steroids. For reference, the the affinity for the androgen receptor (AR) for Testosterone in a recent preclinical model was 29 nM, and 10 nM for DHT.

Unlike testosterone and most other AR mediated anabolic agents, Testolone is orally bioavailable so it does not require injection for proper absorption and it is considered by many researchers to be one of the best SARMs for bulking and adding lean body mass.

Testolone is a fairly recent addition to the list of SARMs for sale; it was developed in 2010 as a possible treatment for osteoporosis and muscle gains. More recent testing performed on rats and primates as well as clinical trials have indicated that it may provide additional benefits as well. 

RAD 140 Benefits from Clinical Research

Muscle Growth:A study on young male cynomolgus monkeys investigated the anabolic effects of 28 days of RAD140 at a dosage of 0.01mg/kg, 0.1mg/kg, and 1mg/kg per day. A mean weight gain of 10% was observed in both the 0.1mg/kg/day group and the 1mg/kg/day group, indicating a quantity response curve that leveled off and provided no additional benefit with higher quantities.

There was no consistent effect on body fat mass in either group, however muscle mass increased in the 0.1 and 1mg/kg/day groups. No significant increases in liver enzymes or prostate weight were reported in either group suggesting a high level of selectivity for androgen receptors in muscle tissue.

Neuroprotection:Androgens have shown clinical significance in preventing neuronal apoptosis and improving cognitive function in Alzheimer’s Disease (AD), primarily through a nongenomic mechanism of the Androgen Receptor (AR). Rapid phosphoinositide 3-kinase/Akt signaling, activated by androgens, regulates the expression of proteins linked to apoptosis such as bax, seladin 1, survivin, XIAP, and bcl-xl.

Androgens can also maintain the integrity of neurons and thus improve cognitive function. Studies have shown that Aβ impairs synaptic structure and function of hippocampal neurons which is reversed by androgen administration resulting in improved cognitive performances in AD animal models. Although the underlying exact mechanisms are not yet fully understood, androgen’s action of inhibiting Aβ-induced apoptosis appears to play a role.

Cellular Protection:A 2014 study investigated the neuroprotective effects of RAD140 on cultured neurons and male rats that were lesioned with kianate. The experiment included two parts – one in vitro involving cell cultures and another in vivo through animal testing.

Results from the in vitro study showed that RAD140 was able to prevent cell death and restore mitochondrial membrane potential, indicating that it could offer neuroprotection much like testosterone and other androgens investigated for these effects.

The in vivo experiment tested the efficacy of RAD140 on male rats with kainate-induced seizures and showed a significant reduction in seizure activity compared to controls. Overall, this study demonstrated that RAD140 is capable of offering neuroprotection both in vitro and in vivo, suggesting it may one day have a place in treating neurological disorders.

Why is Sports Technology Labs the best liquid RAD 140 to buy online?

A recent study involving chemical analyses of 44 different products sold and marketed as SARMs 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.

Many websites offer RAD 140 for sale but Sports Technology Labs is the best place to buy Liquid RAD 140 online because of their consistent, verifiable high quality products, safer bottling and packaging, fast shipping, and great customer service. The internet seems to be full of sites offering Testolone and related substances. This may leave you wondering which of these many options you should select.

Some websites are more interested in making quick cash than in ensuring that their customers receive dependable products. That’s why you need to buy only from websites with established quality-control procedures.

When you buy Sports Technology Labs SARMs 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.

There products come in glass bottles with fixed glass droppers to prevent the leaching of unwanted plasticizers like BPA and extend shelf life, and prevent contamination between uses with external measuring tools. 

they run a transparent business, with no discreet payment methods necessary and no misrepresentation of our products, only the highest quality research chemicals available online.

Side effects of RAD 140

While RAD 140 and other SARMs do not cause androgenic side effects to the same extent as anabolic steroids like Testosterone, reports have revealed the potential for nausea, aggression, reduction in natural testosterone levels, or mild male pattern hair loss from the use of RAD 140. A single-member case report indicated drug-induced liver injury after 11 months of the use of an anti-depressant, as well as intermittent use of RAD 140 and LGD-4033.

The limitations of this study however are the fact that it includes only one test subject, 11 months of concurrent antidepressant use, the quality and quantity of SARMs used by the subject were not monitored, and additional comorbidities were not investigated.

Several case reports exist indicating the potential for selective androgen receptor modulators to contribute to liver injury but none involve a significant sample size or test controls to date. Like other SARMs, RAD 140 may trigger a negative feedback loop and a reduction in natural testosterone production and testicle size though further research is needed to determine the likelihood and severity of this occurrence.
