Ok. Your receptors are probably woken up by now. I'll bet the first couple times in each area produced some serious pip and heated swelling. Right? Now, you'll probably not experience much pip as long as you are using areas you have injected before. If you're continually getting pip a few weeks in, it's probably high BA. Or your body doesn't like something in the mix/oil or contaminant. But if your pip goes away in week 2 - 4, that usually us an indication your receptors in that muscle group "recognize" the juice. If you wanna test this theory, pick a spot you haven't pinned yet (chest, lats, traps,) and really enjoy the pip! Happy pinning!
