I’ve gotten a great deal of help with supplementation from herman_gill and silverhydra.
Picking through supplement misinformation and overhype from people trying to make a buck is difficult to do. The best source for tested information is PubMed, but it’s not an easy task to pick through these published papers.
I’ve created a static supplements page to keep track of things I’ve tried, and if I thought they worked/were worth it or not. I plan to keep this updated as I try and either keep or reject new things. I do mix powders into my morning and evening protein shakes, it’s cheaper than buying pills and easier to dose. I have a script that I use to build mixes, I plan on publishing this at some point when I find some cheap hosting for it.
