Oxycodone is a potent opioid pain medication that should only be used under the supervision of healthcare professionals. The absence of a prescription raises red flags as it is necessary for ensuring proper dosage and patient safety. Additionally, buying medications online can be risky due to the proliferation of counterfeit drugs and unreliable sellers. The availability of payment via PayPal might give a false sense of security, but it is important to note that legitimate pharmacies require an authenticated prescription before dispensing controlled substances like Oxycodone.
