Is it supposed to burn?

Hi guys i just got some test cypinate. it is of tokoyo brand and i was wondering if it is supposed to burn when u shoot it in . thanks

Everyone I’ve heard of that used this stuff says it causes intense pain and flu symptoms that don’t go away quickly. Don’t be surprised if your ass gets really red and bloated either. This stuff is not high quality people. It’s made in freakin Mexico for ANIMALS.
