Note: give yourself considerable time between each of these steps. Rub on arm, wait fifteen minutes. Rub on cheek, 30 minutes. Rub on lips, wait an hour. Put a bit on your tongue, and spit - wait two hours. Eat the teensiest bit, and wait 8 hours. If you still haven’t had a bad reaction, then maybe eat a berry or two, and wait another 8 hours.
If you rush the process, you might die.
Same. I still report to reddit when I need to check something technical. For example, was looking at doing some work on my HVAC and wondering if some new pipe fittings were any good. Googled the product name plus Reddit to get the professional discussions from the HVAC experts.
