I'm using it right now to help me recover from my motorcycle accident, wherein I tore my left tricep and my right hamstring. It's been 12 days and I'm no longer limping and I have full range of motion of my arm. Granted still can't push any significant weight yet, but I can still move some weight and hit the gym.... after only a week and a half. I was told by the doc, no lifting or training for 4-6 weeks. MC IGF is my Miracle in a Bottle. Only administering 80mcg into the tricep area, and within days I went from not being able to use my arm to having full use... now waiting for the strength to get back to normal. Thanks MC and Presser for making this amazing compound available to us at such a great price. If you have not used MC's IGF yet, you really need to pull the trigger and do yourself the favor.
