It's not "excruciatingly" painful but there is a noticeable bite to it. It will catch you off guard the first time, just keep injecting slowly and the PIP will subside pretty quickly as it enters your system. Load your syringe, and then wrap it in a heating pad or run it under warm water. Then put the heating pad on the injection site after you're done, or take a hot shower. I fucking love base/suspension/no ester.. I have tried nandrolone no ester and test no ester. Stacked with 300mg caffeine before the gym is god mode.
