"It's not your testosterone" my urologist said, leaning forward.
"What you're experiencing is vascular decline. It happens to most men after 40."
He drew three quick circles on his notepad.
"First, your nitric oxide drops—your blood vessels can't expand like they used to."
"Second, blood doesn't stay trapped in the tissue. You get hard, but can't stay hard."
"Third, your arteries lose flexibility. That's why you're at 70% hard instead of 100%."
"So this isn't just aging?" I asked.
"Exactly. It's circulation breakdown. And there's a natural compound that fixes it—without Viagra dependency."
