Why this site exists
Regenerative medicine has a trust problem. On one side are bold marketing claims that go well past the evidence. On the other are blanket dismissals of a field that includes real, peer-reviewed science and at least one FDA-approved cell therapy.
People trying to make sense of it deserve better than either. Vivonyx is a plain-English library of what the research shows about stem cells, PRP, exosomes, and related treatments, including the parts that are disappointing or still unknown.
What we cover
The basics: what different products are, where they come from, and how they're thought to work.
Research by condition: knees, backs, nerves, tendons, and more, using the strongest studies we can find.
Regulation, in neutral terms: what's approved, what isn't, and what that means when you're reading about a product.
Questions to ask: practical, research-based questions to bring to any healthcare provider.
What we don't do
We don't sell treatments or products on this site.
We don't run ads, sponsored posts, or affiliate links.
We don't publish testimonials, before-and-after stories, or outcome promises.
We don't diagnose or recommend treatments for individuals. That's a conversation for you and a licensed clinician.
The standard every article meets
Linked sources. Every factual claim points to a study, guideline, or official source we've opened and checked.
Strongest evidence first. Systematic reviews and large randomized trials count for more than small or uncontrolled studies.
Limits stated plainly. Sample sizes, missing control groups, short follow-up, and industry funding are called out.
Corrections welcome. If we got something wrong, email us and we'll fix it and note the change.
