IM4U is a good and reputable IOP. I have purchased from them on a number of occasions and have been consistently pleased with their performance. However, I have had some side effects from the Darvocet I purchased, ie: headaches, ears ringing, difficulty focusing eyes, metallic taste in mouth, and a general "speedy" feeling. Although the product was blister packed and looked legit, I am sufficiently concerned about these potentially dangerous side effects to toss the rest of the product in the trash.

That being said, I have had very good results with Raj's other products.
