(OTCQB: ong>ETSTong>) ("ong>ETSTong>" or "theCompany"), a unique biotechnology company focused on nutraceuticals, bioceuticals and dietarysupplements, announces positive progress on its High Grade CBD (Cannabidiol) Rich Hemp Oil invitro studies on various human primary cells with DV Biologics, a leading biological company. In order toassure the public that ong>ETSTong> provides the best High Grade CBD (Cannabidiol) Rich Hemp Oil, we continueto focus on providing the public with sound scientific research and keeping the public informed on theprogression of studies being done on our Hemp CBD products. DV Biologics, which is independentlytesting our ong>ETSTong> High Grade Hemp CBD Oil in vitro on various human primary cells, has informed us ofthe progression of studies being done. The goals of these studies are to test if ong>ETSTong> High Grade CBD RichHemp Oil serves as a neuroprotectant which may help with neurodegenerative disorders."Testing compounds in vitro on human cells is difficult. We recently tested various concentrations ofong>ETSTong> High Grade CBD Hemp Oil on various cells to see which concentrations are toxic to cells and notedthat the cells grow similarly in concentrations from 1-10 micromolar. This is exciting news as it showsthat this product, ong>ETSTong> High Grade CBD Hemp Oil, may be used in varying concentrations withouttoxicity to different cell types. We are now ready to test whether ong>ETSTong> High Grade CBD Hemp Oil canstop or deter free radical formation that occurs in vitro with brain cells. In order to do so, we will usevarying concentrations of ong>ETSTong> Hemp CBD Oil and induce oxidative stress on brain cells. We will thentest the cells to see if the ong>ETSTong> Hemp CBD Oil reduces oxidative stress and free radical formationcompared to a control cell type that has no ong>ETSTong> High Grade CBD Hemp Oil. We look forward toreporting the full study in the near future," stated Dr. Rafael Gonzalez, Vice President of Research &Development of DV Biologics."We want the public to know that our goal is to provide the best High Grade CBD (Cannabidiol) RichHemp products proven by sound scientific studies. This is why we obtained the services of anindependent entity in DV Biologics. We are eager to hear the results from these studies as we believeour Hemp CBD Oil may be promising for helping those that suffer with neurodegenerative disorders.ong>Scienceong> is what will progress the future of ong>ETSTong> High Grade CBD (Cannabidiol) Rich Hemp products,"stated Matthew Cohen, CEO of ong>ETSTong>.The use of human primary cells provides alternatives to using animal cells and performing animal studieswhich may not translate well into the human condition. It also allows for the specific targeted studiessuch as those described herein which will focus on reducing free radical formation and oxidative stressin the brain. Following these studies, in vivo studies will be needed to determine the ultimate effects ofong>ETSTong> CBD rich hemp oil serving as a neuroprotectant.ong>ETSTong> has the world's leading raw full spectrum, CO 2 extracted, all natural, organic and scientificallyformulated "High Grade CBD Rich Hemp Oil." ong>ETSTong> is focused on the science, research and studies of itsHigh Grade CBD Rich Hemp Oil as a nutraceutical and dietary supplement. ong>ETSTong> has 2 provisional patentsand inventions with its CBD Rich Hemp Oil (CANNABIDIOL COMPOSITIONS INCLUDING MIXTURES ANDUSES THEREOF Patent Serial No. 62102538 and CANNABIDIOL COMPOSITIONS AN DUSES THEREOFPatent Serial No. 62061577). Additionally, ong>ETSTong> has a total of ten (10) new claims for its CBD Hemp Oil.
