Just a follow up the yohimbine was a great addition to the EC stack. I only needed to add 7.5 to 9 mcg of yohimhine to the EC stack which really gave it a nice kick. It has been a few months and I am going to run the ECY stack again really soon. I recommend starting with just the EC and adding in the yohimbine when you have adjusted to the EC stack as the addition of thee yohimhine will bring it to the next level!
