The most painful part of that stack isn't the ArA induced DOM's but the total cost with pure PA

You're right about the PA cost and I really don't know what makes it so expensive to manufacture. IF (and this is a biggie), you're cool with soy product, you can always source the PA from purified lecithin granules that are standardized to all the phospholipids and meter it out to get the PA you want. A good brand will give you the phospholipid breakdown.
And I hate to semi-hijack this post, but I'm interesting in hearing your thoughts about your cortisol support above - why and how you feel Reduce XT is more effective than Suppress-C? How can you tell one's effectiveness over the other? I'm not asking to be critical, but rather that I'm going to be running my first PH cycle vv soon and have both on hand for cortisol control in PCT and honestly couldn't decide which to use and at what dosage. Any experience insight you have would be appreciated.
