Certain herbals tend to work best when not taken daily. BOOST is designed to be "cycled" -- that is, taken for a few days, then not taken for a few days. Or just taken as needed.
We use a high potency horny goat weed, standardized to 20% icariin. Other horny goat weed products are often standardized to 10% or less (or not standardized at all), and some are standardized to icariins (plural) rather than icariin (singular), meaning they are including other related compounds in the standardization, instead of standardizing for pure icariin. The horny goat weed in BOOST is among the most potent you can buy!
We also include true catuaba, in the form men most often want (Erythroxylum catuaba). Check the labels carefully, and you'll find that other catuaba products often use some other related herb instead.
Whether you take it by itself or with our NewVigor daily product, we are confident you'll be happy with BOOST and we stand behind it with a full money back guarantee if you're not completely satisfied.
