Remember, they usually dose fentanyl in micrograms. So, always start with 1/3 or 1/4 of your regular dose until you get used to it. 6. If you use Fentanyl on a regular basis, your tolerance will go up. Keep that in mind if other batches don't seem as strong. Most likely your tolerance has gone up, not that the quality or strength of the fent has gone down. 7. Safety is number one. If you are not familiar with it. PLEASE DONT ORDER!! 8.
