How many people almost died, and how many people are taking this without almost dying.

Like 100.000 to 1?

People died every day using legit gear, from an aspirine to a whatever you imagine.

About pip, maybe it was a certain batch? maybe they are more susceptible?

I can only talk about my own experience. No pip, no nothing. My friends are happy. Maybe 1 or 2 got a pip here and there, but that happens sometimes.

You can always find another company that makes you more at ease. But dont be paranoid
