Sheen says he now see's HIV as a way to help others. "I feel like I'm carrying the torch for a lot of folks out there that are suffering from the same thing," the 51-year-old explained.
He mentioned a new drug he is helping the Food and Drug Administration study.
"I am so grateful, for eight months now, I've been enrolled in an FDA study ... for a medication for a drug called PRO-140." he added.
The drug, he states, is "very close to being approved."
"It's not this hideous cocktail that, that, that leads to so many side effects and, and just, just so much disdain, you know, emotionally and physically. It's one shot a week, and there's no side effects," Sheen said.
Sheen announced he was HIV positive in November of 2015 four years after he was diagnosed.
