Most would tell you to frontload 3-4 times a day, 1 serving is normally 5g. Make sure you drink a lot of water for the first 5 days. After the frontload of 5 days, its back to 1 serving. This isn't true for all brands, but that has been my experience with most Crea Monos. Personally, I'd stay away from any Creatine Monohydrate because of the excessive bloating compared to "specialized" creatines like CEE, Creatine Magnesium Melate (in Green Mag), or mixed formulations, something like Size On. A cycle is probably 6-8 weeks, many people strongly believe in "cycling" creatines, or basically switching to other kinds to get the reaction of it just being introduced.
