This product is not the Turkesterone you typically see. Barlowe's product is standardized to 10% Turkesterone by HPLC! Other vendors advertise 10%, but that is usually 10% by UV, which generally translates to approximately 5% HPLC. So this product is twice the strength. Plus, the bio-availability of Barlowe's Turkesterone is greatly increased by the fact that it is complexed with two percent (12mg per capsule) of 95% Piperine (Black Pepper Extract). Piperine is known for it's ability to increase absorption of hard-to-absorb herbal products. This yields a highly effective, bio-available product without having to ingest a lot of sugar like you have to do in a lot of the other Turkesterone products on the market. Just pop open a capsule of this product and taste it! You will immediately see that this is the real deal!
