Pantothenic Acid (B-5) (250 caps/500 mg)
Take 10/d (5000mg) for 5 days = 50 capsules
Take 4/day (2000mg) there after for 50 days = 200 capsules
That's 55 days (nearly 2 months) for $13
Even if you bought two bottles to double dose what I outlined (which is not required IMHO) that would be nearly 2 month for $26.
