Herbstrong Sports Recovery products are full of the highest quality CBD in the market. Herbstrong labeling and marketing on the internet says "hemp extract" instead of the verbiage "CBD" because of marketing restrictions. Our product IS in fact, sourced from the FULL hemp plant. It is NOT hemp seed oil. The definition of our product is hemp extract which contains the broad spectrum (THC extracted) of cannabinoids and terpenes. The mg on the bottle is the CBD in the entire bottle, the serving size is listed on the back. For example, our 1000mg bottle is 4mg per drop - 1000mg in the 15ml bottle.
