Nice info ITT. Don't have much experience with supps. Tried creatine quite some time back, and I would say there was may be 5-10% improvement in the lifts, so this probably works.
The only supp I am taking now is Body Fortress whey protein. I get it from Walmart, damn cheap and I use it mostly as a mid-afternoon snack and a post-workout shake. Good way to ingest some protein while at work in the middle of a hectic day.
I am trying to lean out a bit, so a couple of month down the line I might try some fat burners out there, but as of now I dont really have much idea whether they work, or which ones are good.
