When you're dealing with high-purity research compounds, precision is everything
They consist of two main components: the nucleus pulposus (a gel-like center) and the annulus fibrosus (the tough outer layer)
Using the same spot over and over can lead to the buildup of scar tissue (lipohypertrophy), which can impair absorption and make injections more difficult and painful
