I've pinned DHB from 3 different labs. The pip was manageable. Some shots were smooth, some hurt.. no rhyme or reason. If you are worried about pip, don't take more than 1ml of DHB at once, and mix it with Test.
What got me with DHB wasn't really the pip, but it gave me a tightness through my VG up into my lower back. Felt like a head tweaked something, and assumed that was it. At the time I was taking 2ml DHB with 1ml of Test 2x per week, rotating glutes. When I stopped pinning the DHB, the lower back tightness went away. I've put a lot of gear in my glutes over the years, and nothing has caused this besides the DHB.
Whether you find your "pip free" DHB or not, I can say your muscles won't like it. It will be all about how it effects you and how much you can handle.
