Ok, first I have taken Ostarine. It is classified as a performance enhancing drug. It was developed as a drug to prevent muscle wasting in cancer patients. Weight lifters use it to preserve muscle on a cut (diet to cut down on fat). It is not an anabolic steroid. It does not really add to strength. It does increase glycogen storage in muscle greater than creatine which makes them feel harder while using it.
Three Clemson players have been suspended for using it. Dabo Swinney is playing off as innocent that it could have been from protein, hair products, drinks, creams.

That is complete bullsh1t. You can only get Ostarine from research chemical labs. You know exactly what you are buying. It comes either in powder you suspend yourself or suspended in liquid to be dosed with an oral syringe.
You don't get it strolling into GNC and buying a tub of protein powder. Or going in to Walmart or Ulta for hair care products. You have to know research chemical labs that sell it to buy it.
