Bleh.
I'm *supposed* to take a teaspoon of MSM with juice and protein powder, vit C, biotin, and vitB5 in the morning with breakfast and in the evening with dinner. That's about every 12 hours. (I eat lunch in my office away from the supplements.)
I personally get faster growth from MSM than from biotin, and I don't have to mail order the MSM like I did the Freeda biotin. When the biotin runs out, I won't reorder.
