Each spray has a different purpose, Anti-Aging for cell renewal and heart health, Multi-Vitamin for core nutrition and immunity, Vitality for energy, stamina and libido and S.L.I.M. for healthy weight management. I've personally tried each one and I have to say they are very easy to use, simple to carry around and taste great, in fact the weight loss one is really delicious! You do have to hold the bottles upright as you spray, or they can dribble a bit, but once you know this you make sure you get it right. The herbs above also give you a lot of general health benefits, as well as attacking the main causes of low libido. Today, you don't have to buy all these herbs separately. Tongkat Ali is another great herb proven to increase levels of testosterone. The Method and Madness range includes four new Irish whiskeys. Each whiskey has its own twist; a single pot still Irish whiskey finished in French chestnut, a single grain Irish whiskey finished in virgin Spanish oak, a single malt Irish whiskey enhanced by French limousin oak and a 31-year-old single cask, single grain limited edition bottled at cask strength.
