I had good results with both TwinLab and Evolution-X, but I was less oily with TwinLab. Also, the B-complex built into the Evolution-X makes me itch for an hour after I take it. Some people reported GNC didn't work for them. I heard B5 is fragile, so maybe some of the bottles that got heated or were outdated. Who knows? I would think getting it in a store would be better than having it shipped and put in a hot mailbox all day. I may reconsider the GNC myself next time.
Anyone else have good or bad experience with certain brands?
I take 6 grams a day and still have no breakouts.
