I'm starting to think a lot of it depends on the person, and how your body reacts to the benzyl alcohol. Some may be able to tolerate it without any reaction or irritation at the site, others react to it. My pain is always worse the 2nd day and continues until about day 4 or 5 depending on the site.
I browsed some other site and some people have had pain in the beginning and then after a couple of weeks it wasn't as bad. Some people also suggested using an antihistamine - the logic being it's an allergic reaction causing the pain. Several people also made the statement that test cypionate was pain free as weel as all the other injectables they have tried, but test enanthate always gave them a lot of pain. I'll keep using it for another week or two and see how it goes. If the pain continues I may switch to test cypionate.
