* Woman of Childbearing Potential (WOCBP) (defined as women with less than 12 months of amenorrhea).
* Unable to understand and/or perform the functional tests, as judged by the Investigator.
* Current physical/rehabilitation therapy (except for passive physical therapy)
* Substance abuse (including but not limited to alcohol, cannabis, narcotics, pain medication) as judged by the investigator.
* Smoking or vaping of products containing nicotine, tobacco or any other products, currently and in the past 1 year.
* Study participant is known positive for hepatitis B surface antigen (HBsAg), hepatitis C antibody (HCVAb) or human immunodeficiency virus-1/2 antibody (human immunovirus 1/2Ab)
* All participants will be encouraged to follow a healthy diet. Caloric restriction will not be pursued.
* Smoking of tobacco, marijuana or any other inhaled products (vaping) are prohibited during treatment and during the follow-up period
* There is no restriction on caffeine consumption
* Occasional alcohol consumption is acceptable, however the participants will be prohibited to consume alcohol 72 hours (3 days) prior medical and laboratory visits
* All participants in the trial (including placebo group) will be encouraged to increase daily physical activities. The participants can follow any preferred physical activity (walking, running, swimming, bicycle, treadmill, etc.), it can be evaluated by summed duration of a variety of activities, such as household work. The activity is measured by the sensors of the wearable activity tracker; thus, the nature of the activity is not critical.
* Activities that are conductive to falls and accidents are discouraged. Examples include horse riding, skiing, skydiving, scuba diving, mountain biking, bungee jumping, etc.
* Participant must be able to wear an activity tracker device daily, optional during sleep, and must be aware of the requirements to charge the tracker or transfer the data.
