Not to flame any one but, don't f*cking put it in the freezer. Thats just stupid. Just put a tiny bit of it on your index finger and dab it on your tongue. If it feels really numb and give you kinda a tingling sensation then your alright.
I have heard many bad things about loeffler sus. I tried the taste test and it did NOT numb. I have heard that it may just be test ent?? Does Enath numb?
the only thing that makes your mouth numb is the benzyl alcohol, not the test. So if your tounge doesnt go numb then theres probably no benzyl alchol in it, and we all know you need BA to suspend the test in the oil.
Loffler sust. is cheap ( a plus) it is rumored to be underdosed. But have never seen tests on it. I have used it and it was ok. If someone were to counterfit something I doubt it would be a loffler product.
