Anyone want to burn their stinging Amopure? Hear me out…

Trifluoroacetic acid (TFA) can be difficult to remove completely during the purification process, potentially leading to trace amounts remaining in the final product.
Injections containing TFA can cause significant pain and discomfort, similar to a strong burning or stinging sensation.

It takes specialized lab equipment to test for the presence of TFA.

However, there is an unhealthy way to potentially test for TFA yourself:
Carefully burn a very small amount of the powder in a well-ventilated space. TFA can have a distinct, pungent odor, similar to vinegar but sharper and more acidic. TFA fumes are toxic, so if you can smell it then you shouldn’t keep smelling it…

Why would you do this if it's toxic

"Geez this amopure burns... maybe i should smoke it instead "

Just complain to the sales rep and see if they offer a refund or a replacement

Why would you inject it in your body if it’s toxic? We just need one person to see if it’s true.

High presence of TFA will make the solution acidic and based on some that tested pH, it's not the case and I doubt they are adding any kind of pH buffer to their Tirz.

The most likely cause, I think, is the filler used.
