I have a friend that uses a lot of IP products. The probelm with the pain for the injectibles is a thing of the past (except for some really strong, really painful crap that he sells and warns you it is painful to inject). My friend added about 40 pounds in a year using just IP injectibles so they must be effective. Serous strenght gains as well.
The prices are good. Shipping is secure but rather odd. If you want a fancy bottle, go somewhere else.
