I don't know where you live, but in the US, Percocet is a controlled substance, and purchasing it without a prescription can lead to big trouble. See a doctor. This is not a medication that anyone should be purchasing online. Apart from the fact that it is highly addictive, the online sellers who make it available are not likely to be trustworthy, and you could be purchasing expired medication, or medication that has been tampered with, or totally fake medication.
It is illegal to purchase controlled substances from online sellers. You need to be seen by the doctor and obtain a legitimate prescription.
It is also dangerous to do order controlled substances online.
