Joy Kong, MD, explains rare skin and systemic reactions to testosterone and peptides in stem cell treatments, occurring in about 1 per 200-300 patients. Most cases involve histamine sensitivity. Screening and preventive H1 and H2 blockers before treatment can reduce reactions.

About 1 in every 200–300 patients (speaker said “in every maybe 2, 300 patients”).

Pre-treatment with H1 and H2 blockers before giving the cells.

Chapters

Some people react to testosterone, some people react to other peptides, and these are supposed to be natural elements. So there could be a lot of these reactions that we don't really understand why, but people who have a tendency for sensitivity. So these patients who have a tendency to overreact, they could break out with a rash. And I've seen that in every maybe 2, 300 patients. So it's still very rare, but it can happen. That's why I screen patients for history of these histamine over activity. And then if I do, then I'll give them an H1 H2 blocker before the patient gets the cells so that we can dampen that overreaction.
